Ok have tested using nRF Connect on the PC and it operates as expected and the DEVICE_NAME updates correctly. So as you say it looks like an issue with caching on the phone or the application.

I guess if the cached info is held in the phone and cannot be invalidated by the application then it will be hard for you to fix. I am talking about IOS here not Android as I haven't yet tested android due to lack of a device.

Hi Dml,

We need to verify if the advertising device name is actually not changed or it's just the phone didn't update the advertising packet.

Please try to turn off and on Bluetooth, on the phone, remove any bond information with the original device.

Also you can use nRF Connect on PC to verify the actual advertising packet.
