And I insert that

advdata.name_type =BLE_ADVDATA_SHORT_NAME;

Thanks, Pål Håland !

I put this line " sd_ble_gap_device_name_set(my, (uint8_t *)DeviceName, strlen(DeviceName)); "

after ble_stack_init();

and before advertising_init();

However the device name is still unknown.

Thank you so mush

Hi Kyu, you need to call the sd_ble_gap_device_name_set after you have called the ble_stack_init and before you call the advertising_init.

Thanks John.

I edited the main function

int main(void) {

#define DeviceName "MyBeacon"

ble_gap_conn_sec_mode_t *my;

my = (ble_gap_conn_sec_mode_t *)malloc(sizeof(ble_gap_conn_sec_mode_t));

my->sm=1;
my->lv=1;

//sd_ble_gap_device_name_set(ble_gap_conn_sec_mode_t const * const p_write_perm, uint8_t const * const p_dev_name, uint16_t len));
sd_ble_gap_device_name_set(my, (uint8_t *)DeviceName, strlen(DeviceName));

// Initialize.
leds_init();
ble_stack_init();
advertising_init();

// Start execution.
advertising_start();



// Enter main loop.
for (;;)
{
    power_manage();
}

}

But the device name is still unknown.

Is there any problem in my code?

Thanks John!

But I don't understand sec_mode parameter. \n

in the main function:

#define DeviceName "JK's Beacon"

// Initialize. leds_init(); ble_stack_init(); advertising_init();

// Start execution. advertising_start();

sd_ble_gap_device_name_set(&sec_mode, (uint8_t *)DeviceName, strlen(DeviceName));

what parameter should I put down?

The device name is set in gap_params_init with the following line of code:

err_code = sd_ble_gap_device_name_set(&sec_mode, (uint8_t *)DEVICE_NAME, strlen(DEVICE_NAME));
