BLE communication with Android



  • Hi all, I'm working on this project that requires a LoPy4 to exchange data to an Android device via Bluetooth. I'm using BLE Scanner on Android to connect to the LoPy4, but I'm facing many obstacles while setting it up for BLE communication.

    I tried following the tutorials on these pages but they haven't been of much help. I recently tried this code, but an error was raised (OSError: Erorr while sending BLE indication/notification).

    Is there any other easy way or sample to set up communication via BLE?

    The firmware on my LoPy4 was updated recently (1.20.2.r0).
