802_15_4 example, how to build test environment an run this example.

[Eton]

I used two development boards with 52840, Two development boards are running 'first' and 'second' in the '\examples\802_15_4\wireless_uart\secure', respectively.

Additionally, I have connected P0.06 to the Rx of the serial port tool, and P0.08 to the Tx. I'm not sure whethe my program has been successfully executed or not." 

And second program can only transmit to the first only once.

Make sure to check the following:Initialization: Ensure that both boards are properly initialized and configured for UART communication.
Buffer Handling: Verify that the receiving board is correctly handling incoming data and that its buffer is cleared or reset after the first transmission.
Serial Port Tool: Confirm that your serial port tool is set up correctly to receive data. Sometimes, settings like baud rate or data bits can affect communication.
Error Handling: Look into any error handling mechanisms in your code that might prev

Hello,

Please check out description on how to setup the boards:

As configured in the picture, it seems that communication can only be successful once.

Is the design of this example intended to be like this? I don't quite understand the communication principles of 802.15.4.

Hope to receive your assistance, thank you.

I have already read the link, but I'm not sure what the result of the example is.

Resolved.  Flow control - RTS/CTS is necessary
