This example is a simple TSCH node used to test uart1 functionality of a JN516x on a node. Note: uart0 is usually configured as serial port for flashing the JN516x and for logging and debug output.

The TX output of uart1 is represented as a PUT/POST resource for a Coap client. A string entered on a Coap plug-in of a browser will be forwarded over the wireless TSCH network to the the TX output of UART1.

The RX input of uart1 is represented as an OBSERVABLE resource for a Coap client. If a string is entered on uart1 that is terminated with a Line Feed or Carriage Return, a Coap event will notify Coap clients to issue a GET event. This will make string available at the Coap client side.

The example has been verified on a DR1174 evaluation board
