nRF52832 Bluetooth peripheral_uart sample: use RX data and not sent to BLE

[BradEA]

I want to intercept some data in the RX (in section UART_RX_READY in uart_cb() as a command with arguments.  And I do not want this data to be sent on the the BLE.

After I get the data that I want, what should I do with the buf, so the process continues getting new data from the UART RX?

Do I just k_free(buf)?  Or something else?

[BradEA]

Also, is there a more complete description of this sample or what's involved with how this all works?

Does this always require a carriage return or linefeed character before actually sending to the BLE?

I need it to just send raw data and send when a timeout occurs (50 msec) or the buffer is full.

The sample's documentation contains all the description of its function. Let me know if there is anything in particular that is not covered there that you have questions about.

Yes, the buffer filling for a single message will end when the \n or \r character is received, as shown in the UART_RX_RDY handling.

Best regards,

I want to be able to send any number of bytes without using \n or \r characters to indicate end of the input data packet, if possible.

And I want the program to not lose data in the middle of sending data to the BLE Tx, regardless of its MTU size.

I don't understand how data input to the uart ends up at the UART_RX_READY point in the code.
