Hi,

I'm not sure why you would get a RX error when don't have Putty open. Did you use the default UART RX pin (P0.08) when you tried this on the Nordic DK?

Hey Vidar,
The event raised when NRF_DRV_UART_EVT_ERROR (I find out it by using breakpoints) has occurred.
It only happen when putty is NOT open.
I test it with our custom board and with nordic dk and I get the same error.

Thanks!

The APP_UART_COMMUNICATION_ERROR event is raised when one of the UART Error conditions has occured. Does this only happen when you don't have putty open? Also, are you testing with a nordic devkit or a custom board?

void uart_error_handle(app_uart_evt_t * p_event)
{
    if (p_event->evt_type == APP_UART_COMMUNICATION_ERROR)
    { // ***HERE :
        APP_ERROR_HANDLER(p_event->data.error_communication);
        // ---
    }
    else if (p_event->evt_type == APP_UART_FIFO_ERROR)
    {
        APP_ERROR_HANDLER(p_event->data.error_code);
    }
}

Thanks

Hello,

Could you please include the code where the "ERROR 4 [NRF_ERROR_NO_MEM]" message gets printed? app_uart_get() should only return NRF_ERROR_NOT_FOUND or NRF_SUCCESS as far as I can tell.
