nRF Mesh and uart

[ps_anu]

hi..... everyone 

I want to send the data from one node  to particular node and that same data should want to print in termite using uart . so i checked the ble_uart coexist example .so how to do this task . in this case which example i should use to pass the data from one to another node .

anyone can explain me clearly how do achieve this ?

Hi,

You should be able to print the data by adding UART to the Mesh example. I suggest you have a look at this, Integrating Mesh into nRF5 SDK examples.

What do you mean by "I have entered the message in message paaramater"? The UART Coexistence example simulates a button press over UART, which will turn on/off a LED on a Light switch server. You should start with the Light switch example, the client can send a message to the server then server prints out the message via UART.

As per you said client can send a message to server then server print out the message via uart . In this case what you are Mean to message. I have understood message mean like hi hello strings right ? Exactly same thing i wanT to do ... how to Send the message from one node to another and print via uart what function i have to use To pass the string message

[Mttrinh]

The message that is sent in the example, is data and not a string. In the light switch example, a message is sent from client to server. You have to add UART to the server node if you want to print out the message.

Thanks . Which function is used to pass the data from client to server . 

[Mttrinh]

access_model_publish(...) is used to send data from client to server on the access layer. Have a look at this function on the application layer generic_onoff_client_set(...).

 here i have set my message , is it correct pls check here

static void button_event_handler(uint32_t button_number)
{
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Button %u pressed\n", button_number);

    uint32_t status = NRF_SUCCESS;
    generic_onoff_set_params_t set_params;
    model_transition_t transition_params;
    static uint8_t tid = 0;

    /* Button 1: On, Button 2: Off, Client[0]
     * Button 2: On, Button 3: Off, Client[1]
     */
 char arr[5] = "code";
 char ara[5] = "set";
 
    switch(button_number)
    {
        case 0:
        case 2:
            set_params.on_off = arr;
            break;

        case 1:
        case 3:
            set_params.on_off = Ara;
            break;
    }

    set_params.tid = tid++;
    transition_params.delay_ms = APP_CONFIG_ONOFF_DELAY_MS;
    transition_params.transition_time_ms = APP_CONFIG_ONOFF_TRANSITION_TIME_MS;
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Sending msg: ONOFF SET %d\n", set_params.on_off);


    set_params.tid = tid++;
    transition_params.delay_ms = APP_CONFIG_ONOFF_DELAY_MS;
    transition_params.transition_time_ms = APP_CONFIG_ONOFF_TRANSITION_TIME_MS;
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Sending msg: ONOFF SET %d\n", set_params.on_off);
