ESP32-ScanMyTesla

CAN to BlueTooth Adapter for ScanMyTesla on ESP32

Hardware

  • Any ESP32 based board. (e.g. Wemos D1 mini ESP32), doesn't work with ESP32-C*, -S*, -H* series, only with ESP32
  • Any DC-DC Step Down to 5V, because most ESP32 boards can't handle car voltages (~16V). (e.g. DC Power Shield for WEMOS D1 mini)
  • SN65HVD230 CAN bus transceiver without termination resistor
  • Tested with Arduino ESP32 Core v3.0.4
  • Does NOT work with iOS. Apple doesn't Bluetooth Serial.
