how to send mac address as characteristic value?

[rushin]

hello! i want to send mac address of my bluetooth device. i have written function

uint32_t get_address(void)
{
    uint32_t err_code;
    ble_gap_addr_t  ble_gap_addr;
    memset(&ble_gap_addr, 0, sizeof(ble_gap_addr));
    ble_gap_addr.addr_type= BLE_GAP_ADDR_TYPE_PUBLIC;
    err_code = sd_ble_gap_address_get(&ble_gap_addr);
    return(err_code);
}

but i can't store data into array. can you help me?

The return value of your function get_address() is not mac address but the error code of nRF51 SDK. The value is NRF_SUCCESS or NRF_ERROR_INVALID_ADDR.

then what should i return value?

[monpetit]

like this:

ble_gap_addr_t ble_gap_addr;

uint32_t get_address(void)
{
    return sd_ble_gap_address_get(&ble_gap_addr);
}

int main(void)
{
    ......

    while (1) {
        uint32_t err_code;
        err_code = get_address();
        APP_ERROR_CHECK(err_code);
        err_code = custom_service_update_data(m_conn_handle, ble_gap_addr.addr);
        APP_ERROR_CHECK(err_code);
        app_sched_execute();
        power_manage(); 
    } 
}
