I don't see how this differ from the bt_set_name() function and the NVS backend, please try explaining what exactly you mean by this that isn't covered by bt_set_name().

Hi,

Now I have a new problem that how to write the name that changed when code is running in the advertising packet.

In order to change name,I need a variable to save.but if I want to write into adcertising packet,I need to use the constant and BT_DATA macro.

So,how can I write a alterable name in my advertising packet?

Yes, if you want to set it in the flash (NVS backend) use CONFIG_BT_DEVICE_NAME_DYNAMIC instead of CONFIG_BT_DEVICE_NAME. That should allow you to use runtime configs of your Bluetooth device name. Sigurd explains here that you can use the NVS backend and the bt_set_name() to set the name at runtime.

Hi,

I think I get some methods from them.But I still want to know whether I can start my application without setting

CONFIG_BT_DEVICE_NAME in prj.conf but write a expected name into flash as NCS change BLE device name during runtime do?

You can try setting CONFIG_BT_DEVICE_NAME_DYNAMIC=y in prj.conf and use bt_set_name in application.
