Crashing during DFU

[Redguy1986]

Version 4.1.0. iPhone 5c, IOS 9.3.4
I choose DFU mode, then push button "Select Device". The app crashes down.
I choose UART mode, I have the same behavior after "Connect" button pressed.
I tried it in app from official AppStore

When I tried the app on iPhone 5s with iOS 10 it works properly.

Ok let's see, you're saying it crashes only on iOS10 ?

[Redguy1986]

No.
It crashes on iOS 9.3.4.
I've tried it on iOS 10, and the app works well.
So, it depends on iOS version

[mostafaberg]

Ok so it works ok here on iOS 9, testing on 10 to verify, but if it works here on iOS 9 ..

Can you help out by attaching your device crash logs ?

[Redguy1986]

How can I help you?
I tried to get logs in iTools program.
Look at these files:
itools_log.txt
nRF Toolbox-2016-10-07-121411.ips.txt
nRF Toolbox-2016-10-07-121438.ips.txt
Are they useful for you?

They are not symbolicated so it's a bit hard to know what happened exactly.
Can you plug it into XCode, and export the last crash report from the device manager there and send me that file ? it's ok if that's not symbolicated too as long as you are using the exact last version form the app store

[Redguy1986]

I'm sorry, I can't use Xcode. I'm an application user, not an iOS developer. Besides, I use Windows7 on my PC and I have no possibility to use apple features or programs.

[mostafaberg]

Ah ok, thought you had a development environment, ok i'll try to reproduce here and see what I can do, it doesn't reproduce that's the problem, but will experiment and try to see if I can resym your crashes so I can understand what's going on, will keep you updated.
Thanks a lot for your help!

This crash occurs on iOS 10.1 (on iOS 10 works perfectly). I was able to download sources and launch nRFTToolbox and the issue is with class NORScannerViewController line 168:

Could not cast value of type 'NSKVONotifying_CBPeripheral' (0x174300bd0) to 'nRF_Toolbox.NORScannedPeripheral' (0x100163e28).

When I updated iOS to 10 version this issue was still there.
Right now I've updated NRFToolbox to 4.1.1 version from appstore and the issue disappeared.
Thank you.

On iOS10.1 crash still exists.

Can you release this fix to the AppStore?

We will publish it tomorrow or on Wednesday, sorry for the delay, but I'm also working on new version of DFU library and need to finish it before.
