General rule of thumb: if you’re seeing an something that looks like an interoperability issue with iOS, please file a bug with as much information about the problem as you can provide. The Bluetooth team loves fixing issues like this and well-written bugs from our developers help immensely to see what’s happening "on the ground", so to speak.

I’m seeing the same thing on iOS 9.3 using a Ti CC2640 with Ti's BLE Stack 2.1, so i doubt this is Nordic specific.

Does that mean that the Nordic chip has an issue with its stack, or does the iOS stack have an issue where it can't handle a situation where an ACK doesn't happen?

How did you actually fix the issue? Are you able to get down to that low level when programming on an iOS device?

I am working on a iOS 9+ ble app that talks to a Nordic nRF51. I have a couple remote beta testers who have reported after n number of successful connections, the bluetooth on their device stops working and the only way to fix it is to turn on/off bluetooth on the device. I am assuming something I am doing is crashing the bluetooth daemon but have not been able to reproduce this myself.

I wanted to know if this has happened to anyone else or if there are any suggestions on how to troubleshoot a situation like this?
