Thank you, that helps. It looks like the problem is that you do not release the RX buffers after they have been processed in the NRF_LIBUARTE_ASYNC_EVT_RX_DATA event. You need to call nrf_libuarte_async_rx_free(), with with the received buffer and length, if not the library will run out of buffers to use.

E.g:

case NRF_LIBUARTE_ASYNC_EVT_RX_DATA
    strcat(uart0_array, p_evt->data.rxtx.p_data);
    // Done processing buffer, release buffer back to libUARTE
    nrf_libuarte_async_rx_free(p_libuarte, p_evt->data.rxtx.p_data, p_evt->data.rxtx.length);
    break;

Hi,

Can you post the full output from your RTT Viewer window? It is not visible in your screenshot exactly where the error occurred. It is also strange if you managed to end up in the error handler with an error code of zero (NRF_SUCCESS).

Best regards,
Jørgen
