Device is not updated after update for iOS

[CGS]

On using your DFU code in iOS-nRF-Toolbox, We were only able to reset the BLE device It same happen on use iOS-nRF-Toolbox to update firmware.

Can you elaborate? What is it that you are not getting? The idea is to capture a trace of the on air packets between the iOS device and the nRF Device?

I have checked above User Guide but not getting exact idea.

I do not quite understand what you mean when you state the following:

In nrf ToolBox source code, Why my BLE device disconnect when I select device it will connected but once BLE device reset it will be automatically BLE disconnect 

 I would recommend using the nRF Connect app over the nRF Toolbox as it will generate a log output that you can attach to this question.

I really need to see a sniffer trace to see if the nRF device is advertising correctly after being put into bootloader and if the iOS device is issuing the connection request. We do have a video that explains how the nRF Sniffer works, see https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Sniffer/Get-Started#infotabs.

You said:

So the nRF Toolbox app is connecting to the nRF device in bootloader mode but is automatically disconnected? How do you see this?
