RE: crashing bluetooth on device
by Ephram Cohen 25 Apr '16

To clarify: I saw the issue on a different chip than the Nordic. My issue was similar enough to the OP's (locking up the BT stack on the iDevice) to warrant a response. I have no direct experience with the Nordic chip/stack misbehaving. Indeed, the project that I did do with the nRF51 some time ago did not suffer from this malady.

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. > On Apr 25, 2016, at 12:59 PM, Rene Limberger <rl(a)favionics.com> wrote: > > 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. > > >> On Apr 25, 2016, at 12:44 PM, Alex.SneedMiller <Alex.SneedMiller(a)target.com> wrote: >> >> 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?

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. > On Apr 25, 2016, at 12:44 PM, Alex.SneedMiller <Alex.SneedMiller(a)target.com> wrote: > > 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?
