Board: DOIT ESP32 DEVKIT V1
ELM327: Generic Bluetooth OBD-II Adapter
Library Used: ELMduino
Baud Rate: 115200
Tested On: Arduino IDE 2.3.2 (also tested on earlier versions a year ago)

ELM327 discoverable under the name: "OBDII" by the ESP

What I’ve Tried
Verified MAC address and device name (OBDII)
Re-tested ELM327 via mobile apps (works fine)
Reduced baud rate from 115200 to 38400 and vice versa
Used BluetoothSerial.connect(address) with known MAC
Tried ELM_PORT.begin("ESP32", true, 10000); with/without pin
Library and board package are up to date
