didWriteValueForCharacteristic not trigger short time after connection in IOS #99

After connection, didWriteValueForCharacteristic trigger correctly after calling writeByteArray() function, but after some random time, it does not trigger, but it successfully write data to peripheral.

Steps to reproduce the behavior:

  1. Connect a peripheral from an IOS device.
  2. Set Notify Value as true to read characteristic after connection
  3. Send data to write characteristic and see didWriteValueForCharacteristic trigger in PeripheralDelegate.kt file
  4. Wait a little bit, approximately 5-10 seconds and try again, peripheral can get the data but didWriteValueForCharacteristic not trigger anymore.
  5. Disconnect device and reconnect. See same behaviour, the function trigger at the beginning and then it brokes.

didWriteValueForCharacteristic must be triggered after every writeByteArray() function's call.

All Apple devices show same behaviour. (Iphone 7 (IOS 15.6.1), Iphone 8 (IOS 15.6.1), Ipad 9 (IOS 16.1.1), Mac M1 (Ventura 13.0.1))

There is no any problem with Android devices.
