Hi,

Your code will always advertise the name in DEVICE_NAME. This is because you have already generated the advertising packet by the time you call sd_ble_gap_device_name_set() again with DEVICE_NAME_2. You need to generate the advertising data again after calling sd_ble_gap_device_name_set() for that to be reflected in the advertising data. Since you use the advertising module, you should call ble_advertising_advdata_update() (which in turn calls ble_advdata_encode()).

How to do that?? How to update the advertise data again?  ...

You can do it like this after you have called sd_ble_gap_device_name_set():

1. Stop advertising (this can be avoided, but doing so complicated things a bit in SDK 15.x)
2. Generate and configure new advertising data using ble_advdata_encode()
3. Configure the SoftDevice to use the new advertising data by calling ble_advertising_advdata_update().
4. Start advertising again.
