Hi,
I have a custom BTLE sensor (nordic chipset [1]) that works flawlessly when first paired. However, on subsequent app launches it never sends didUpdateValueForCharacteristic.
I can switch apps to Settings and "Forget" the sensor. Then, I can use the same workflow to trigger -peripheral:didUpdateNotificationStateForCharacteristic:error and it starts sending data. If I relaunch the app, the sensor doesn't work until I "Forget" it again.
Basically, it gets to here and continues once… and after that, silence:
[peripheral setNotifyValue:YES forCharacteristic:self.receiveCharacteristic];
Any ideas on why this is happening? I’ve stubbed out all of the delegate methods and nothing is out of the ordinary.
Thanks!
Caylan
