BLE DISCONNECTION PROBLEM

Hi, I am using the UART over BLE example + a timer interrupt + a pwm signal. And I am facing the following problem (error launched by my phone app: )



This happens sometimes and with different apps, so somehow sometimes there is an issue during the connection. 

Can you identify this problem? 

Thanks a lot .

  • Hi Nasib

    This seems to be the infamous 133 error present in some Android phones. This rarely happens anymore, but still occurs in some Android phones. If you're using our Android BLE Library I suggest adding some retries when trying to connect to a device or if you're using another library for your Android app, add a delay when connecting to a device.

    Best regards,

    Simon
