APP UART COMMUNICATION ERROR eror code

[aep]

both for APP_UART_FIFO_INIT and APP_UART_INIT i never receive APP_UART_DATA_READY

but at least i get APP_UART_DATA sometimes. most of the times i get APP_UART_COMMUNICATION_ERROR with uart_evt->data.error_communication being either 1 or 4 or 8 randomly.

what is the meaning of the error code there and how can i use it to determine the actual error? The data on the line looks fine in a logic analyzer.

bah of course i used the wrong file, thanks Ole.

with app_uart_fifo i just get APP_UART_COMMUNICATION_ERROR with error code 4 and no other event.

All of this is with or without flow control btw, but with flow control its a tiny bit better.
