# Lippert OneControl - Analysis Guide
## What We've Accomplished
We successfully:
1. ✅ Extracted the XAPK file
2. ✅ Decompiled the Android APK
3. ✅ Identified the Xamarin .NET assembly blob format (XABA v2.2)
4. ✅ Located 434 .NET assemblies in the payload
5. ✅ Identified key BLE service UUID
6. ✅ Mapped RV control systems
## Key Findings
### Bluetooth Protocol
- **Service UUID**: `c4570b0f-2eeb-428b-b55c-8fa225621e86`
- **Library Used**: Plugin.BLE (Xamarin Bluetooth plugin)
- **Protocol Type**: BLE GATT (Read/Write/Notify characteristics)
### RV Systems Controlled
- Awnings (extend/retract)
- Lights (on/off, possibly dimming)
- Water Pumps
- Water Tank Sensors
- Slide-outs
- Heating Systems
### Command Types
From code analysis, the system uses:
- `RelayBasicSwitch` - Simple on/off relays
- `RelayBasicLatching` - Latching relays
- `RelayMomentary` - Momentary/pulse relays
- Message-based protocol with device IDs
### Key Assemblies to Analyze
The protocol implementation is in these DLLs:
1. **OneControl.Direct.IdsCanAccessoryBle.dll** - BLE protocol for IDS CAN accessories
2. **OneControl.Direct.MyRvLinkBle.dll** - MyRV Link BLE protocol
3. **OneControl.dll** - Core OneControl library with device definitions
4. **Plugin.BLE.dll** - BLE communication library
5. **IDS.Portable.CAN.dll** - CAN bus protocol (if using CAN gateway)
## Next Steps - Manual Analysis with ILSpy
Since the Xamarin assemblies are in a complex format, here's how to analyze them manually:
### Option 1: Use Android Studio APK Analyzer
```bash
# Install Android Studio, then:
# File > Profile or Debug APK
# Select: extracted/com.lci1.lippertconnect.apk
# Navigate to lib/armeabi-v7a/libassemblies.armeabi-v7a.blob.so
# Android Studio can sometimes extract these automatically
```
### Option 2: Use Online .NET Decompiler
1. Go to: https://www.decompiler.com/
2. Upload `arch_apk/lib/armeabi-v7a/libassemblies.armeabi-v7a.blob.so`
3. Let it extract and decompile the assemblies
4. Download the decompiled source code
### Option 3: Use `pyaxmlparser` and manual extraction
```bash
pip3 install --user pyaxmlparser
# Then write a custom Python script to parse XABA format
```
### Option 4: Recommended - BLE Sniffing When You Get Access
When you have access to your camper in April, this is the FASTEST way:
1. **Using nRF Connect App** (Easiest):
- Install nRF Connect on your phone
- Scan for your OneControl device
- Connect and explore services/characteristics
- Try writing values and observe what happens
- Document the commands
2. **Using Android HCI Snoop** (Most detailed):
```bash
# On your Android phone:
# Settings > Developer Options > Enable Bluetooth HCI Snoop Log
# Use the Lippert Connect app to control your RV
# Control each system (lights, awnings, pumps, etc.)
# Pull the log:
adb pull /data/misc/bluetooth/logs/btsnoop_hci.log
# Analyze with Wireshark:
wireshark btsnoop_hci.log
# Filter by: bluetooth.uuid == 0xc4570b0f
```
## What to Look For in ILSpy/Decompiled Code
When you get the assemblies decompiled, search for:
### 1. Characteristic UUIDs
```csharp
// Look for GUID/UUID definitions
public static Guid ServiceUuid = new Guid("c4570b0f-2eeb-428b-b55c-8fa225621e86");
public static Guid CharacteristicUuid = new Guid(...);
```
### 2. Command Building
```csharp
// Look for methods like:
byte[] BuildCommand(DeviceType type, CommandType cmd, params)
byte[] BuildRelayCommand(int deviceId, bool state)
```
### 3. Device IDs/Addressing
```csharp
// How devices are identified:
enum DeviceType { Light = 0x01, Awning = 0x02, ... }
class Device {
int Id;
DeviceType Type;
}
```
### 4. Message Format
```csharp
// Packet structure:
[StartByte][Length][Command][DeviceID][Data...][Checksum]
```
## Protocol Reverse Engineering Worksheet
When analyzing, fill this out:
### Message Structure
```
Byte 0: [?] # Start byte or length?
Byte 1: [?] # Command type?
Byte 2: [?] # Device ID?
Byte 3-N: [?] # Data
Byte N+1: [?] # Checksum/CRC?
```
### Known Commands (to discover)
```
Light On: [??][??][??]...
Light Off: [??][??][??]...
Awning Extend: [??][??][??]...
Awning Retract: [??][??][??]...
```
### Device IDs (to discover)
```
Living Room Light: 0x??
Kitchen Light: 0x??
Awning: 0x??
Water Pump: 0x??
```
## Building the Home Assistant Integration
Once you have the protocol documented, creating the HA integration will be straightforward:
### 1. Create Python Library
```python
# lippert_onecontrol/client.py
import bleak
class OneControlClient:
SERVICE_UUID = "c4570b0f-2eeb-428b-b55c-8fa225621e86"
CHAR_WRITE_UUID = "???" # From analysis
CHAR_READ_UUID = "???" # From analysis
async def send_command(self, device_id, command):
# Build packet based on protocol
packet = self._build_packet(device_id, command)
await self.client.write_gatt_char(self.CHAR_WRITE_UUID, packet)
```

- Configuration via YAML or UI
**Implementation:**
```python
# Key libraries needed
- bleak (Python BLE library)
- homeassistant.components (HA integration)
```
## Step-by-Step Implementation
### Phase 1: Protocol Discovery (Current Phase)
- [ ] Complete .NET assembly decompilation
- [ ] Capture Bluetooth packets using HCI snoop
- [ ] Document command structure
- [ ] Identify all GATT characteristics and UUIDs
### Phase 2: Python Library Development
Create a Python library `pylippert_onecontrol`:
```python
# pylippert_onecontrol/client.py
from bleak import BleakClient
import struct
from .cobs import encode_packet # Implement COBS + CRC8
# Confirmed UUIDs from Decompiled Code
SERVICE_UUID = "00000030-0200-A58E-E411-AFE28044E62C"
CHAR_READ_UUID = "00000034-0200-A58E-E411-AFE28044E62C"
CHAR_WRITE_UUID = "00000033-0200-A58E-E411-AFE28044E62C"
class OneControlClient:
def __init__(self, address):
self.address = address
self.client = None
self._seq = 0
async def connect(self):
self.client = BleakClient(self.address)
await self.client.connect()
def _next_seq(self):
self._seq = (self._seq + 1) & 0xFFFF
return self._seq
async def send_command(self, cmd_type, table_id, payload):
# 1. Build Packet
# [Seq (2)] [CmdType (1)] [TableID (1)] [Payload...]
seq = self._next_seq()
packet = struct.pack("<HB", seq, cmd_type) + bytes([table_id]) + payload
# 2. Append CRC8 (Init=0x55)
crc = calculate_crc8(packet, init=0x55)
packet += bytes([crc])
# 3. COBS Encode
encoded = cobs_encode(packet)
# 4. Write
await self.client.write_gatt_char(CHAR_WRITE_UUID, encoded)
async def turn_on_light(self, light_id):
# ActionSwitch (0x40), Table 1, On (1)
# Payload: [State=1] [DeviceID]
await self.send_command(0x40, 1, bytes([1, light_id]))
async def turn_off_light(self, light_id):
await self.send_command(0x40, 1, bytes([0, light_id]))
```
### Phase 3: Home Assistant Integration
#### Directory Structure:
```
custom_components/lippert_onecontrol/
├── __init__.py # Integration setup
├── manifest.json # Integration metadata
├── config_flow.py # Configuration UI
├── const.py # Constants
├── light.py # Light entities
├── switch.py # Switch entities (pumps, etc.)
├── sensor.py # Sensor entities (tanks)
├── cover.py # Cover entities (awnings, slides)
└── climate.py # Climate entities (heating)
```
#### Integration Code Skeleton:
```python
# custom_components/lippert_onecontrol/__init__.py
async def async_setup_entry(hass, entry):
"""Set up Lippert OneControl from a config entry."""
device = OneControlDevice(entry.data["address"])
await device.connect()
hass.data[DOMAIN] = device
# Forward setup to platforms
await hass.config_entries.async_forward_entry_setups(
entry, ["light", "switch", "cover", "sensor", "climate"]
)
return True
```
### Phase 4: Device Entities
#### Example: Light Control
```python
# custom_components/lippert_onecontrol/light.py
from homeassistant.components.light import LightEntity
class OneControlLight(LightEntity):
def __init__(self, device, light_id, name):
self._device = device
self._light_id = light_id
self._name = name
self._state = False
@property
def name(self):
return self._name
@property
def is_on(self):
return self._state
async def async_turn_on(self):
await self._device.control_light(self._light_id, True)
self._state = True
async def async_turn_off(self):
await self._device.control_light(self._light_id, False)
self._state = False
```
#### Example: Awning Control (Cover)
```python
# custom_components/lippert_onecontrol/cover.py
from homeassistant.components.cover import CoverEntity, CoverDeviceClass
class OneControlAwning(CoverEntity):
_attr_device_class = CoverDeviceClass.AWNING
async def async_open_cover(self):
await self._device.control_awning(self._awning_id, "extend")
async def async_close_cover(self):
await self._device.control_awning(self._awning_id, "retract")
```
## Next Steps
### Immediate Actions Needed:
1. **Bluetooth Packet Capture**
```bash
# On Android device with app
adb shell settings put secure bluetooth_hci_log 1
# Use the Lippert Connect app to control devices
adb pull /data/misc/bluetooth/logs/btsnoop_hci.log
# Analyze with Wireshark
```
2. **Extract .NET Assemblies**
- Need to properly extract DLLs from the Xamarin blob
- Decompile with dnSpy or ILSpy
- Document complete command structure
3. **Test BLE Connection**
```python
# Quick test script
import asyncio
from bleak import BleakScanner
async def scan():
devices = await BleakScanner.discover()
for d in devices:
print(f"{d.name}: {d.address}")
if "OneControl" in str(d.name) or "Lippert" in str(d.name):
print(f"Found potential device: {d}")
asyncio.run(scan())
```
4. **Manual BLE Exploration**
- Use nRF Connect app to explore OneControl device
- List all services and characteristics
- Try writing test values to understand command format
## Alternative: Existing Solutions
Before building from scratch, check:
1. **Lippert API**: Contact Lippert for official API/SDK
2. **Existing Projects**: Search GitHub for "OneControl", "Lippert", "MyRV"
3. **RV Forums**: Check iRV2, Forest River forums for existing integration work

# Lippert OneControl - Complete Implementation Guide
## 🎉 Protocol FULLY REVERSED
All protocol details have been extracted from the decompiled source code. You can now build the Home Assistant integration **immediately** without waiting for April!
## Protocol Specification
### BLE UUIDs (CONFIRMED from DirectConnectionMyRvLinkBle.cs:28-34)
```
Service: 00000030-0200-A58E-E411-AFE28044E62C
Write Char: 00000033-0200-A58E-E411-AFE28044E62C
Read Char: 00000034-0200-A58E-E411-AFE28044E62C
Version: 00000031-0200-A58E-E411-AFE28044E62C
```
### Encoding (from DirectConnectionMyRvLinkBle.cs:44)
```csharp
CobsEncoder(prependStartFrame: true, useCrc: true, frameByte: 0, numDataBits: 6)
```
### Packet Structure (Unencoded)
**Before COBS encoding:**
```
[Seq (2 bytes, LE)] [CmdType (1)] [TableID (1)] [Payload...] [CRC8 (1)]
```
**Indexes (from MyRvLinkCommandActionSwitch.cs):**
- Bytes 0-1: Client Command ID (sequence)
- Byte 2: Command Type
- Byte 3: Device Table ID
- Byte 4: Device State (for ActionSwitch)
- Byte 5+: Device IDs
### Command Types (from MyRvLinkCommandType.cs)
```
GetDevices = 1
ActionSwitch = 64 (0x40) - Lights, Pumps, Fans
ActionMovement = 65 (0x41) - Awnings, Slides
ActionDimmable = 67 (0x43) - Dimmable Lights
ActionRgb = 68 (0x44) - RGB Lights
ActionHvac = 69 (0x45) - HVAC/Climate
```
## Python Implementation
### 1. COBS + CRC8 Implementation
Based on `IDS.Portable.Common.COBS/CobsEncoder.cs` and `Crc8.cs`:
```python
# cobs_protocol.py
import struct
from typing import List
class Crc8:
"""CRC8 with init value 0x55 (from Crc8.cs)"""
POLY = 0x07
def __init__(self, init: int = 0x55):
self.value = init
def update(self, byte: int):
self.value ^= byte
for _ in range(8):
if self.value & 0x80:
self.value = ((self.value << 1) ^ self.POLY) & 0xFF
else:
self.value = (self.value << 1) & 0xFF
def update_buffer(self, data: bytes):
for b in data:
self.update(b)
@staticmethod

# Update code byte
output[code_index] = count + 1
# Skip frame bytes
while i < len(data_with_crc) and data_with_crc[i] == self.frame_byte:

return bytes(output)
class CobsDecoder:
"""COBS Decoder for responses"""
def __init__(self):
self.frame_byte = 0x00

i += 1
# Add frame byte if not at end
if code < 0xFF and i < len(encoded):
output.append(self.frame_byte)
# Verify CRC
if len(output) > 0:
data = output[:-1]
received_crc = output[-1]
calculated_crc = Crc8.calculate(bytes(data))
if received_crc != calculated_crc:

await asyncio.sleep(1)
# Turn off light
await client.turn_off_light(5)
finally:
await client.disconnect()
if __name__ == "__main__":
asyncio.run(main())
```
## Testing Steps
### 1. Find Your Device
```bash
# Run scanner
python3 -c "
import asyncio
from bleak import BleakScanner
async def scan():
devices = await BleakScanner.discover(timeout=10.0)
for d in devices:
print(f'{d.name}: {d.address}')
asyncio.run(scan())
"
```
### 2. Get Device IDs
Once connected, send GetDevices command to discover all your RV devices and their IDs.
### 3. Test Commands
Try turning lights on/off to verify the protocol works!
## Next Steps
1. **Test the Python client** with your RV (in April or now if you have access)
2. **Document device IDs** for your specific RV setup
3. **Build Home Assistant integration** using the templates in `HOME_ASSISTANT_INTEGRATION.md`
4. **Create config flow** for easy setup
5. **Publish to HACS** for the RV community!

- Found initial service UUID reference
- Identified controllable RV systems
### Phase 2: Assembly Extraction
- Installed Dexamarin and dependencies
- Battled with XABA v2.2 format (not supported by standard tools)
- Used ilspycmd to decompile .NET assemblies
- **Successfully extracted ALL 431 assemblies!**
### Phase 3: Protocol Analysis
- Analyzed decompiled C# source code
- Found actual UUIDs in `DirectConnectionMyRvLinkBle.cs`
- Discovered COBS encoding in `CobsEncoder.cs`
- Mapped complete command structure from `MyRvLinkCommandType.cs`
- Built Python implementation from C# logic
---
## Key Files

## What You Can Do NOW
### Option 1: Test Immediately (if you have RV access)
```bash
# 1. Install dependencies
pip install bleak
# 2. Use the Python client from IMPLEMENTATION_GUIDE.md
# 3. Scan for your device
# 4. Send GetDevices command
# 5. Control your lights!
```
### Option 2: Build Home Assistant Integration
```bash
# 1. Follow HOME_ASSISTANT_INTEGRATION.md
# 2. Create custom component
# 3. Implement light, switch, cover entities
# 4. Test with your RV
# 5. Publish to HACS!
```
### Option 3: Wait Until April
- Everything is ready
- Just need physical device access
- Can test entire integration quickly
- Estimated time: 1-2 days for complete HA integration
---
## Technical Highlights
### The COBS Encoding Challenge
The most complex part was understanding the COBS encoding:
- 6-bit data packing (max 63 bytes per chunk)
- Frame byte: 0x00
- Prepended start frame
- CRC8 appended before encoding
- Custom implementation matching C# source
### Sequence Number Discovery
Found that each command needs:
- 16-bit sequence number (increments with each command)
- Little-endian encoding
- Wraps at 0xFFFF
### Device Table ID
All commands use Table ID = 1 (discovered from decompiled code)

# Lippert OneControl Bluetooth Protocol - Reverse Engineering Findings
## Overview
This document contains findings from reverse engineering the Lippert Connect app (v6.2.2) to understand the Bluetooth protocol used by OneControl RV control panels.
## App Architecture
- **Platform**: Xamarin (C#/.NET on Android)
- **BLE Library**: Plugin.BLE (Xamarin Bluetooth plugin)
- **Package**: com.lci1.lippertconnect
## Bluetooth Information (CONFIRMED)
### Service UUIDs
- **Service**: `00000030-0200-A58E-E411-AFE28044E62C`
- **Write Characteristic**: `00000033-0200-A58E-E411-AFE28044E62C`
- **Read Characteristic**: `00000034-0200-A58E-E411-AFE28044E62C`
(Note: The `c457...` UUID found earlier might be for a different device type or cached).
### Protocol Structure
The communication uses a custom packet format wrapped in **COBS (Consistent Overhead Byte Stuffing)** encoding.
**Packet Structure (Unencoded):**
```
Byte 0-1: Sequence Number (Little Endian, unsigned short)
Byte 2: Command Type (byte)
Byte 3: Device Table ID (byte, usually 1)
Byte 4-N: Payload (Command specific data)
Byte Last: CRC8 (Calculated over bytes 0..N, Init=0x55)
```
**Encoding:**
1. Construct the packet.
2. Calculate CRC8 (Init 0x55) and append it.
3. Encode the entire buffer using COBS (Start byte 0x00, 6-bit packing).
### Command Types (`MyRvLinkCommandType`)
- `0x01` (1): **GetDevices**
- `0x40` (64): **ActionSwitch** (Lights, Pumps, etc.)
- `0x41` (65): **ActionMovement** (Awnings, Slides)
- `0x43` (67): **ActionDimmable** (Dimmable Lights)
### Payload Examples
**Turn Light ON (Device ID 0x05):**
- Command: `0x40` (ActionSwitch)
- Table: `0x01`
- Payload: `[0x01 (On)] [0x05 (Device ID)]`
**Turn Light OFF (Device ID 0x05):**
- Command: `0x40` (ActionSwitch)
- Table: `0x01`
- Payload: `[0x00 (Off)] [0x05 (Device ID)]`
**Get Device List:**
- Command: `0x01` (GetDevices)
- Table: `0x01`
- Payload: `[0x00 (StartID)] [0xFF (MaxCount)]`
### Key DLL Assemblies
- `OneControl.Direct.MyRvLinkBle.dll` - Contains the BLE connection logic and UUIDs.
- `OneControl.Direct.MyRvLink.dll` - Contains the Command classes and Enums.
- `IDS.Portable.Common.dll` - Contains `CobsEncoder` and `Crc8` logic.
## Next Steps for Complete Protocol Understanding
To fully reverse engineer the protocol, we need to:
1. **Extract and Decompile .NET Assemblies**
- Use a proper Xamarin assembly extraction tool
- Decompile with dnSpy or ILSpy to see actual command structures
2. **Bluetooth Packet Capture**
- Use Android's HCI snoop log or Wireshark with Bluetooth adapter
- Capture actual packets during device control
- Analyze packet structure and command bytes
3. **Alternative Approaches**
- Check if Lippert has published any API documentation
- Look for existing open-source implementations
- Contact Lippert for developer API access
## Tools Needed for Further Analysis
### For .NET Assembly Extraction:
```bash
# Install Xamarin assembly extraction tools
# Option 1: xamarin-decompress (if available)
# Option 2: Manual extraction from blob
# Install .NET decompiler
sudo pacman -S ilspy-bin # or dnspy on Windows
```
### For Bluetooth Sniffing:
```bash
# Enable HCI snoop on Android device
adb shell settings put secure bluetooth_hci_log 1
# Pull HCI log
adb pull /data/misc/bluetooth/logs/btsnoop_hci.log
# Analyze with Wireshark
wireshark btsnoop_hci.log
```
### For Protocol Analysis:
- **Wireshark** - Packet analysis
- **nRF Connect** (Android/iOS) - BLE exploration and testing
- **Bluetooth HCI Snoop** - Packet capture
## Contact Information
- **Developer Support**: service@lci1.com
- **Phone**: +1 432-LIPPERT
- **GitHub**: https://github.com/lci-ids/app.c (referenced in code)
## Notes
- The protocol appears to be proprietary
- Commands are likely simple relay on/off with device addressing
- May use standard BLE characteristics for read/write/notify
- Protocol implementation is in C# code (not visible without proper decompilation)

# Lippert OneControl Reverse Engineering - Summary
## Mission Accomplished ✓
We successfully reverse engineered the Lippert OneControl Bluetooth protocol.
**MAJOR SUCCESS**: We extracted the assemblies, decompiled the code, and fully documented the protocol structure!
## What We Discovered
### 1. Bluetooth Protocol Details (CONFIRMED)
- **Service UUID**: `00000030-0200-A58E-E411-AFE28044E62C`
- **Write Char**: `00000033-0200-A58E-E411-AFE28044E62C`
- **Encoding**: **COBS** (Consistent Overhead Byte Stuffing) + **CRC8**
### 2. Extracted Assemblies
We successfully cracked the XABA v2.2 compression format and extracted 431 assemblies.
We decompiled the key libraries using `ilspycmd` and found the source code for:
- `OneControl.Direct.IdsCanAccessoryBle.dll` - Sensor logic
- `OneControl.Direct.MyRvLinkBle.dll` - **Main Connection Logic**
- `OneControl.Direct.MyRvLink.dll` - **Command Structures**
- `IDS.Portable.Common.dll` - **COBS & CRC8 Algorithms**
### 3. Protocol Commands
We identified the exact packet structure for controlling devices:
- `ActionSwitch` (0x40): Controls lights, pumps, etc.
- `ActionMovement` (0x41): Controls awnings, slides.
- `GetDevices` (0x01): Lists available devices.
## Challenges Encountered
### Modern Xamarin Format
The app uses XABA v2.2 format which we successfully reversed using a custom Python script.
### Solution Accomplished
- ✓ Cracked XABA v2.2 format
- ✓ Extracted all DLLs
- ✓ Decompiled DLLs to C# source code
- ✓ Analyzed C# code to find UUIDs and Command structures
## Recommended Next Steps
### Build the Integration (Now)
You have all the technical details needed to build the Python library and Home Assistant integration.
See `HOME_ASSISTANT_INTEGRATION.md` for the updated implementation plan with confirmed UUIDs and encoding logic.
### Verify with RV (April)
1. Connect using the confirmed UUIDs.
2. Send `GetDevices` to map your RV's specific Device IDs.
3. Enjoy controlling your RV from Home Assistant!
- **Awnings** - Extend/Retract commands
- **Lights** - On/Off control (possibly dimming)
- **Water Pumps** - On/Off control
- **Tank Sensors** - Water level monitoring
- **Slide-outs** - Extend/Retract
- **Heating** - Temperature control
### 3. Command Architecture
The protocol uses relay-based commands:
- `RelayBasicSwitch` - Simple on/off relays
- `RelayBasicLatching` - Latching relays (toggle states)
- `RelayMomentary` - Momentary/pulse relays (like a doorbell)
### 4. App Architecture
- **Platform**: Xamarin .NET (C# code compiled to Android)
- **Assembly Format**: XABA v2.2 (434 .NET DLLs in compressed format)
- **Key DLLs**:
- `OneControl.Direct.IdsCanAccessoryBle.dll` - BLE accessory protocol
- `OneControl.Direct.MyRvLinkBle.dll` - MyRV Link BLE protocol
- `OneControl.dll` - Core device library
- `Plugin.BLE.dll` - BLE communication library
## Challenges Encountered
### Modern Xamarin Format
The app uses XABA v2.2 format which:
- Stores assemblies in a compressed blob inside an ELF shared object
- Uses LZ4 compression for individual assemblies
- Requires special extraction tools
- Current tools (Dexamarin, pyxamstore v1.0) don't fully support this format
### Solution Accomplished
- ✓ Identified `XALZ` magic header for compressed blocks
- ✓ Reversed the block structure (Header + Uncompressed Prefix + LZ4 Stream)
- ✓ Created `extract_xaba_v2_new.py` to extract all 431 assemblies
- ✓ Manually identified key DLLs by content analysis
## Recommended Next Steps
### Option 1: Decompile the Extracted DLLs (NOW)
**You now have the DLLs!**
1. Download the `extracted_assemblies_complete` folder.
2. Open `OneControl.Direct.IdsCanAccessoryBle.dll` in **ILSpy** or **dnSpy**.
3. Look for:
- `BleAccessoryManager` or similar classes
- `BuildCommand` methods
- `GattCharacteristic` GUIDs
- Protocol definition structs
### Option 2: BLE Sniffing (April)
### Option 3: Contact Lippert
They might have official documentation:
- **Email**: service@lci1.com
- **Phone**: +1 432-LIPPERT
- **Ask for**: Developer API documentation for OneControl BLE protocol

```python
# lippert_onecontrol/client.py
import bleak
class OneControlClient:
SERVICE_UUID = "c4570b0f-2eeb-428b-b55c-8fa225621e86"
# Add characteristic UUIDs from sniffing
async def control_light(self, device_id, state):
packet = build_packet(device_id, state) # From sniffing
await self.client.write_gatt_char(CHAR_UUID, packet)
```
### 2. Home Assistant Integration (2-3 days)
- Light entities for RV lights
- Switch entities for pumps
- Cover entities for awnings/slides
- Sensor entities for tank levels
- Climate entity for heating
See `HOME_ASSISTANT_INTEGRATION.md` for complete code templates.
## Success Metrics
What we achieved **without physical access**:
- ✅ Identified BLE service UUID
- ✅ Mapped all controllable RV systems
- ✅ Understood app architecture
- ✅ Located protocol implementation DLLs
- ✅ Created extraction tools and scripts
- ✅ Designed complete HA integration plan
What remains (requires camper or advanced tools):
- ⏳ Extract exact command byte structures
- ⏳ Identify GATT characteristic UUIDs
- ⏳ Document device ID mapping
## Timeline Estimate
**Path A: BLE Sniffing (April)**
- Protocol capture: 30 minutes
- Protocol documentation: 1-2 hours
- Python library: 1-2 days
- HA integration: 2-3 days
- Testing: 1-2 days
- **Total: ~1 week**
**Path B: Assembly Extraction (Now)**
- Tool updates/workarounds: 1-3 days
- Assembly analysis: 2-4 days
- Protocol documentation: 1-2 days
- (Then same as Path A for implementation)
- **Total: ~2 weeks**
## Recommendation
**Wait until April and use BLE sniffing.** It's:
- 10x faster than assembly reverse engineering
- 100% accurate (real protocol, not decompiled approximation)
- Easier to debug issues
- Provides exact byte sequences immediately
In the meantime:
- Review `HOME_ASSISTANT_INTEGRATION.md`
- Set up Home Assistant development environment
- Learn about `bleak` Python library
- Study BLE GATT protocol basics
## Quick Start for April
```bash
# 1. Install nRF Connect on phone
# 2. Enable Bluetooth HCI logging on Android
# 3. Use app, pull logs
# 4. Analyze with Wireshark
# 5. Come back to this project with the protocol documented
# 6. Build HA integration using our templates
```
You're in great shape! All the groundwork is done. When you have camper access, you'll be able to complete this quickly.
