Hi,

I'm not sure that I understand your question.

There's no scanf() in the code, characters either come over the UART or they come over the connection from the app/ other device.

The data from UART is read by the function app_uart_get(&data_array[index]) in the uart_event_handle().

Best regards,

Well, you can set up the receiver so that it the receiver triggers on newlines for example. And also have the transmitter send a newline at the end of each command, for example when enter is pressed.
