Looking for a way to turn car power on/off as a signal via mqtt. I can’t use a battery powered beacon as it would lose the logic for power on/off triggers.
I assume the bluetooth in the car is useless as it stops showing up on scans once paired. It also isn’t BLE.
Is there any way to turn a regular usb bluetooth dongle into a beacon?
My fallback would be to flash esp32 with beacon software and plug it into the usb jack in the car.
