APP UART COMMUNICATION ERROR

[cobo]

Hello,

I am trying to fix the UART communication error(APP_ERROR_HANDLER(p_event->data.error_communication);). I am sending a command(0x87,0x14,0x11,0x33,0x44) continuously(100ms) from mobile app to nRF51822. From nrf51822 I have to send this command to other microcontroller in 30ms interval.

It works good for +-30 sec, but then it crashes. I cannot use flow control. It seems its a common error on the forum. I tried all I could've found but it is still not working.

I have modified ble_app_uart example. SDK: nRF5_SDK_12.3.0_d7731ad Softdevice: 130 Baudrate=115200

I managed to solve my problem by commenting out:

in main:

                   case APP_UART_COMMUNICATION_ERROR:

                 // APP_ERROR_HANDLER(p_event->data.error_communication);

and in app_uart_fifo.c:

                               // app_uart_event.evt_type  =  APP_UART_COMMUNICATION_ERROR;

                                // app_uart_event.data.error_communication = p_event-
                                >data.error.error_mask;

Thanks for updating your question with a solution.

Is it possible to get anymore clarity on this problem please. I have experienced the same issue as the original poster and his solution gets me functional but I'm wondering what the consequences of this are?

This fix will ignore communication error on UART. I will assume that there can be some loss of data.

Instead of using APP_ERROR_HANDLER() upon APP_UART_COMMUNICATION_ERROR, you can handle the error on your own.
