GW Diag
GW Diag talks to the XTOOL GWBT dongle's Bluetooth protocol directly: read and clear codes on every module, watch live data, run actuator tests, and share the dongle with other OBD apps.
The story
- Problem
- The XTOOL GWBT dongle only works with its vendor app, so the owner can't use it with anything else or dig deeper than the app allows.
- Solution
- I reverse-engineered the dongle's protocol and built a scan tool on top of it, with UDS diagnostics per module and a local ELM327 emulator so any ELM327-compatible app can use the dongle too.
- Result
- v0.6 reads and clears codes across the PCM, ABS, cluster, body, steering, airbag and TPMS modules of a 2009 Mazda3, and runs bi-directional actuator tests.
Features
- Auto Scan of every module, with read and clear fault codes
- Live data, OBD-II generic modes and vehicle info (VIN, calibration, ECU)
- Bi-directional actuator tests (UDS 0x2F), each behind a confirm
- ELM Bridge: a local ELM327 emulator so other OBD apps can share the dongle
