o3DIAG - A Open Source OBD-II Diagnostic Tool for Windows and Linux
Bench-only, read-only OBD-Lite MVP pairing Raspberry Pi with STM32 (NUCLEO-F446RE). MCU streams newline-terminated JSON over UART (115200) via ST-LINK VCP; Pi reads and logs now. Next: BLE/GATT bridge and a simulated two-node CAN bench. Simple, reproducible, Pi-first workflow with VS Code + PlatformIO.
🔧 Build a simple OBD-lite MVP with Raspberry Pi and STM32 for telemetry transmission over BLE, using newline-terminated JSON from simulated CAN data.
