I have an app that is running on iOS 6 in my iPhone 4S, and can communicate with my BLE device. Basically the app sees advertisements, and at some point connects to the device. After the connection, and the retrieval of services and the characteristics for each service, the app attempts to write to a characteristic. On iOS 6 this works – I'm able to connect, set the notification state on a given characteristic, and then write to that characteristic and get the didUpdateValueForCharacteristic callback. On iOS 7 all of that works, except that I never get the didUpdateValueForCharacteristic callback. I'm working on getting a BLE packet trace to compare against, but that shouldn't really be necessary. The app code is the same, the BLE device is the same – the only difference is the iOS 7 device. Does this ring any bells?
