e46

BMW I-Bus / K-Bus firmware for ESP32 and Arduino: control the lights, windows and locks of a BMW E46 from your phone over Wi-Fi, plus welcome lights and follow-me-home from the key fob. Schematics and wiring photos included.

BMW E46 cluster with in-game data send through CAN, K-Bus and digital outputs using SimHub as telemetry server

BMW I-Bus / K-Bus library (IBus / KBus) for Arduino, ESP32 and other microcontrollers: read, decode and send messages on classic BMWs such as the E46, E39, E38 and E53. Handles checksums, bus arbitration and transceiver sleep.
