nRF52832 "ble_peripheral->ble_app_uart" stops working

[enkavak]

Hello,

        I am trying to evaluate the "ble_app_uart" in the "nRF5_SDK" and I am using "DVK-BL652-SA-01" development board from LAIRD.

        The example works fine for a while. After some time, the application stops working. I can not even see the BLE device with my phone.

        What could be the problem ? Any idea ?

Best Regards

Hello,

So you are in a connection while this happens, is that right?

 

Can you please try to define "DEBUG" in your preprocessor defines, and set a breakpoint in the error handler in app_error.c. Exactly what line that is on depends on the SDK version. 

 

Does the DVK from Laird come with an external LFXTAL, or does it use the RC Oscillator? If it uses the RC Oscillator, what settings have you used for it?

 

Best regards,
Edvin

Hello Edvin,

      I am using the internal RC oscillator with the settings below.

nrf_clock_lf_cfg_t const clock_lf_cfg =

    {

        .source       = 0,

        .rc_ctiv      = 16,

        .rc_temp_ctiv = 2,

        .accuracy     = 1

    };

I will try to debug it.
