Hi,
I am using NRF51822 pca10028 UART ble example ,
I need to give provision to change the name of the device after pairing and reset the device so that it starts advertising with the name provided by the user,
Thank you

Hi Mttrinh,
I tried using pstorage ,got the data in nus_data_handler() and used sd_ble_gap_device_name_set () passed the value and gave a soft reset sd_nvic_SystemReset() .
The name change works or reflects only in NRF toolbox UART app but when i search in normal BLE Scanner the name is not updated .

normal BLE Scanner
What do you mean by that? What is, "normal"?!
Note that the OS may be "caching" the old name - so you may have to turn the BT off & on again to clear the cache ...
Hi Awneil,
I am using this https://play.google.com/store/apps/details?id=com.macdom.ble.blescanner&hl=en_IN app
You previously said that it was not updated.
Yes i am not seeing the updated name, its shows N/A but in the NRF toolbox UART app ble name is Correctly updated.
Thank you
Like awneil mentioned, you might need to turn Bluetooth off and on again to clear the cache.
HI Mttrinh,
I tried doing that and even i did a hard reset ,its not working .
Kindly guide
Have you tried with nRF Connect? Do you see the same issue?
As i said in the post it works on NRF tool app but i need the updated name to be displayed in normal Bluetooth setting.Is there any other method
Thank you,

Thank you,
Before updating the name via UART, do you get the correct name up in the Bluetooth settings on your phone?
The app get the name from the advertisement packet, while the bluetooth settings get the name using this function BluetoothDevice.getName(). This method just returns the name for this device from the cache. It seems like the issue might be that the cache doesn't get cleared.
