nRF51822 ( S110 )- how can I change the device name?

[Kyu]

Hi, I am trying to change the beacon data.

I changed Beacon UUID already, but I can not find where can I change device name.

I guess I need to change the gap_adv_data. However I can not find that part.

Would you help me to change the device name?

Thanks. Shin

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?

And I insert that

advdata.name_type =BLE_ADVDATA_SHORT_NAME;
