Hello,
I am in the process of migrating my Arduino car trip computer to an ESP32 module. Since the ESP32 has Bluetooth on-board, I would like to use it to send trip computer data from the ESP32 to an Android phone.
So far, so good, the only problem is that I have never done anything involving Bluetooth or BLE.
I have looked at some examples that come with the Arduino ESP32 BLE library, but I haven't quite been able to make out just what exactly is needed in the simplest terms to get my ESP32 to transmit data via BLE.
Have any of you done anything with the ESP32 BLE? Could you point me to some sort of beginner's guide of how to program a BLE device in the Arduino IDE?
