After a client does a successful `await char.notified()`, then before the next call to `notified()` a notification arrives, then they call `notified()` twice before the _next_ notification, the second call will return None rather than waiting. This applies the same fix as in 5a86aa5 which solved a similar problem for server-side `char.written()`. Using a deque is slightly overkill here, but it's consistent with the server side, and also makes it very easy to support having a notification queue in the future. Also makes the client characteristic properly flags/properties-aware (i.e. explicitly fail operations that aren't supported). Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
This allows a server to write a characteristic and automatically notify/indicate all subscribed clients. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
