App always crashes when stopping advertising and central connected #84

Closed kacper1703 closed 3 years ago

kacper1703 commented 3 years ago

App: 2.4.4, build 37, iPhone 11 Pro, iOS 14.1

Repro steps:

In Advertising Tab, create a new Server
Add a service - "Legacy DFU Service"
In the service add a characteristic "Blinky button state", -- properties: Notify, Indicate; -- permissions: none; -- data: Bool (false)
Start advertising
Connect a central and subscribe to notifications on "Blinky" characteristic
(optional) send a value notification to the central
Tap "Stop Advertising"
App crashes

App does not crash if I disconnect the central on the central side, then stop advertising.

Also, any attempt to open control center or moving the app into the background causes the app to crash as well.

@kacper1703 Thank you! We're going to look into this immediately.

dinesharjani commented 3 years ago

@kacper1703 Your first issue, the crash when tapping on "Stop Advertising", has been fixed, and will be part of the next update, 2.4.5.

However, I cannot reproduce the background crash. Do you have specific steps to reproduce it as well?

kacper1703 commented 3 years ago

@dinesharjani They're the same, but instead of tapping "Stop Advertising" I either move the app to the background or for example try to open Control Center. Locking the phone also crashes the app.

dinesharjani commented 3 years ago

@kacper1703 both issues were caused by the same bug; it's fixed and committed to the 2.4.5 branch. Thank you!

kacper1703 commented 3 years ago

Awesome, thank you. When could we expect the 2.4.5 release?

dinesharjani commented 3 years ago

@kacper1703 I expect it to be out very soon - at the latest, middle of next week. But I think sooner, because we're very close to our Christmas break :)
