CocoaMQTT disconnects when phone screen is put to sleep and waken up again. Autoreconnect does not trigger.

Open BrentMifsud opened this issue 4 years ago • 5 comments

Steps to reproduce

  1. create CocoaMQTT instance
  2. turn on autoreconnect
  3. connect to broker
  4. start sending/receiving messages
  5. turn phone screen off.
  6. turn phone screen on.
  7. notice MQTT disconnects with error code 7 (server closed connection).
  8. notice that autoreconnect does not trigger

Current workaround

  1. in the didDisconnect delegate method, I call mqtt.connect() again.
  2. in the connection ack delegate method, I check if ack is accept, otherwise close the connection.

CocoaMQTT V3.1.1 (Release 2.0.9) IOS 16 It still happens.

I use reconnect to solve this problem after active application. NotificationCenter.default.addObserver(self, selector: #selector(reConnectAll), name: UIApplication.didBecomeActiveNotification, object: nil)

In v2.1.5 the client reconnects successfully but previously subscribed topics are not received anymore. Do I have to resubscribe?
