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.

Ok, my bad I though the title of the question,"Device is not updated after update for iOS", meant that the DFU failed after updating the iOS version. 

And you did answer the question related to bonding. Again sorry. 

If the nRF Device is bonded then the nRF device should send a Service Changed indication to inform the Central( iOS device) that the GATT table has changed as the iOS device will cache the GATT table of bonded peers. So the Service Changed Characteristic must be present on the nRF device, but as the DFU is successful when using nRF Connect, it indicates that this is OK. 

I will need to look at 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.
