To know about how to set payload in server side in COAP using contiki cooja simulator.

  • Step 1: Open a file at location:
    home/user/contiki/examples/er-rest-examples/er-example-client.c
    Payload set for client side
    coap_set_payload(request, (uint8_t *)msg, sizeof(msg) – 1);
    function set payload,

  • Payload set for sever side
    For example,
    Char * res_msg = “Pressure”
    coap_set_payload(response, res_msg, strlen(res_msg)); /* a const char str[] and sizeof(str) produces larger code size */

  • Step 3: Run the cooja simulator
