# 2026-04-24 — OpenClaw on Android Head Unit

## Session Start
Topher asked about running OpenClaw on an Android Auto head unit. Found a solid use case.

## Hardware Confirmed

### Head Unit — Topway TS10 (QT10 variant)
- SoC: Unisoc UIS7862, 8-core (2×A75 + 6×A55) @ 1.8GHz
- GPU: Mali-G52
- BT 5.0, 1280×720 IPS
- **RAM: 4GB | Storage: 32GB** ✅
- Firmware variant: VOVOL XC90 20230

### CAN Decoder — Simplesoft HY-SS-04 (uple soft)
- Model: HY-SS-04, P/N: K0090
- Software: V3.01.101BYPT (DC: 2023-06-27)
- Protocol: TTL UART 38400 baud 8N1
- Output: 6-byte CAN frame dumps (e.g. `46 32 02 01 01 XX` for VOL+)
- Compatible: Hyundai Sonata 8 (2011-2014), Sonata 9 (2015-2017), Kia Sportage/Sorento/Cadenza
- Header: 4-pin but only 2 populated (TX + GND likely)

### Car — 2014 Hyundai Sonata Hybrid
- HS CAN on OBD2 pins 6 (CANH) / 14 (CANL)
- CAN decoder wired in, steering wheel controls + door status working

## Connectivity Path
```
Sonata CAN → HY-SS-04 decoder (38400 UART) → TS10 head unit
TS10 BT tethering to phone → OpenClaw gateway on media server (100.91.1.57)
```

## Connectivity Options (优先级)
1. **BT tethering** — recommended; uses BT 5.0 radio, WiFi stays free for wireless CarPlay
2. **Wired USB** — most reliable, good for setup/debugging
3. **WiFi hotspot** — conflicts with wireless CarPlay; use wired or BT instead

## Key Decisions
- Head unit runs voice client only; gateway stays on media server
- BT tethering chosen to preserve wireless CarPlay capability
- CAN sniffing via UART tap (TX line only, 38400 baud) — CH340/FTDI adapters available

## Next Steps
1. Enable ADB on TS10 (Factory Settings → `adbon`)
2. Sideload OpenClaw Assistant APK
3. Configure BT tethering to phone
4. Point to gateway via Tailscale
5. Sniff UART from HY-SS-04 to map byte sequences
6. Steering wheel button → OpenClaw wake
