@petter

thanks again.

q4) I wanted to brodcast an exising service that is available in periperal role , not a new one is it possible? q5) I also didnt see any example of Observer role , can you direct me to that example.

@petter , i am not sure how to add the custom service through this function. how do i connect my service with sd_ble_gap_adv_data_set() ?

What is the problem?

@petter,

your code for the non broadcasting works fine. but am having trouble to add existing custom service to the non connectable advertising. could you provide me a sudo code for this ?

@Petter , hi thanks for the reply.

Q1) if i understand correctly once my periperal role is connected to a central device , i can call sd_ble_gap_adv_start() to do non-connectable advertising ? , can you show me sudo code for this as there is no example for this ?

Q2) the other thing is while am in non-connectable advertising mode how can i adversise we my service ?

Q3) to read this non connectable service , which role does the other ble device has to be observer or central or both are possible ?

I'm actually not aware of any example, but there are several questions about this on DevZone.

It should be simply to set the advertising data with sd_ble_gap_adv_data_set() (through ble_advdata_set()) and call sd_ble_gap_adv_start(). See this MSC.

Please be aware that you per spec only can do non-connectable advertising while in a connection.

Putting in an UUID (service) shouldn't be too hard. I'm not sure what RSSI you would be putting in? What received signal strength would you be putting in?

Edit1:

Q1) Yes. Something like this:

ble_gap_adv_params_t m_adv_params;

m_adv_params.type        = BLE_GAP_ADV_TYPE_ADV_NONCONN_IND;
m_adv_params.p_peer_addr = NULL;
m_adv_params.fp          = BLE_GAP_ADV_FP_ANY;
m_adv_params.interval    = NON_CONNECTABLE_ADV_INTERVAL;
m_adv_params.timeout     = APP_CFG_NON_CONN_ADV_TIMEOUT;

err_code = sd_ble_gap_adv_start(&m_adv_params);
APP_ERROR_CHECK(err_code);

Q2) You need to add your UUID to the ble_advdata_t struct that you give to ble_advdata_set(). You can have a look at how this is populated in one of our examples.

Q3) Both

Edit2:

int main(void)
{
    uint32_t err_code;
    ble_stack_init();
    
    ble_uuid_t    ble_uuid;
    ble_uuid128_t base_uuid = {{0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0, 0x93, 0xF3, 0xA3, 0xB5, 0x00, 0x00, 0x40, 0x6E}};
    
    err_code = sd_ble_uuid_vs_add(&base_uuid, &ble_uuid.type);
    APP_ERROR_CHECK(err_code);

    ble_uuid.uuid = 0x0001;
    
    ble_gap_conn_sec_mode_t sec_mode;

    BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);
              
    err_code = sd_ble_gap_device_name_set(&sec_mode, "propUUID", 8);
    APP_ERROR_CHECK(err_code);
    
    ble_advdata_t advdata;
    memset(&advdata, 0, sizeof(advdata));
    
    advdata.name_type          = BLE_ADVDATA_FULL_NAME;
    advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
    
    advdata.uuids_complete.p_uuids = &ble_uuid;
    advdata.uuids_complete.uuid_cnt = 1;

    err_code = ble_advdata_set(&advdata, NULL);
    APP_ERROR_CHECK(err_code);
                                          
    ble_gap_adv_params_t adv_params;
    memset(&adv_params, 0, sizeof(adv_params));

    adv_params.type        = BLE_GAP_ADV_TYPE_ADV_NONCONN_IND;
    adv_params.interval    = 200;
    adv_params.timeout     = 0;

    err_code = sd_ble_gap_adv_start(&adv_params);
    APP_ERROR_CHECK(err_code);
    
    // Enter main loop.
    for (;;)
    {
        power_manage();
    }
