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.

 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);

[Mttrinh]

Yes, it seems correct. Why have you :

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);

twice?

[ps_anu]

Thanks mttrinh , for your reply . by mistake its copied twice . Now , i have sent this character from client to server , and how do i check whether it is received to server side or not?

here  , below pic client  side debug terminal results after i am  pressing button 1

 here , below pic  server side

Hai Mttrinh
I am following the instruction  as per you said above
But firstly I am trying to send a custom data to uart like

int main(void)
{

initialize();
start();
uart_init();
uint32_t err_code;

do
{
err_code = app_uart_put('p');
if ((err_code != NRF_SUCCESS) && (err_code != NRF_ERROR_BUSY))
{
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "----- UART initiated successfully -----\n");

//NRF_LOG_ERROR("Failed receiving NUS message. Error 0x%x. ", err_code);
APP_ERROR_CHECK(err_code);
}
} while (err_code == NRF_ERROR_BUSY);

in nrf_mesh light_switch example

But i cant able to see any data in my terminal ( I am using tera term with 115200 baud rate)

kindly help me

Best regards

Hi,

This is a very old case, I suggest you create a new ticket and include more information regarding the issue.
