Broken NUS after iOS 10 upgrade

[Tim]

After upgrading to iOS 10, I have been unable to successfully interact with my device using the NUS. I used to use the NUS to communication with the device and retrieve stats. For example, I would send a "T" message to the device and it would respond with some information on the temperature of a couple of thermistors.

Now when I try to send a "T" this is all I see:

Before it used to also show the message that was sent. Now it doesn't show that a message was sent. The following image is taken from two months ago. This is the behavior that I can no longer reproduce but would like to see.

Also, I have noticed the appearance of Optional("...") in interactions since the upgrade. For example, in the first image it first says 'Connecting to: Nordic_UART ...' but then it later says 'Connected to : Optional("Nordic_UART")'. Why has this appeared?

I recreated your problem. Looks like an issue with nRF toolbox as it works with the old nRF UART app I use for testing sometimes. I have registered this in our internal bug tracking system. The iOS devs will look at it in their next sprint planning. For now I suggest you use a different app for testing.

Note: please notify us when creating duplicate cases in both devzone and mypage. Or avoid creating duplicates all togheter... Thanks!

I apologize for my negligence in specifying that I had already created a devzone question when I submitted the mypage issue; I will do so in the future. Thank you for all the quick responses!
