BLE characteristic readValue cannot reliably read data
I am trying to read the value from a characteristic of a BLE device. The code #include <Arduino.h> #include "BLEDevice.h" //#include "BLEScan.h" static const char* TAG = "CtrlMain"; static BLEUUID heightServiceUUID("99fa0020-338a-1024-8a49-009c0215f78a"); static BLEUUID heightCharUUID("99fa0021-338a...
