Automatic reconnecting to a channel leads to not receive messages

[vlavianos]

We are facing the following issue in both Android & iOS SDK:

• We subscribe into a channel of type Timeseries through a normal mqtt subscribe.
• While being subscribed we are receiving messages OK with a certain period.
• After a couple of minutes we get disconnected and then reconnected automatically
• At that point and on, we are not receiving any messages.. although we are connected in the channel.
• If we force a resubscribe then we continue to receive messages OK.

Expected behavior: To continue to receive messages after automatic reconnect

@vlavianos : After talking with product, this is intended functionality. re-subscribing is commonly a task of the application logic, not the MQTT client itself (citing Paho, MQTT.js, etc). I've had a call with the guys in product asking if it would be possible to automatically re-subscribe, and we came up with a couple of options internally that would satisfy the need but all require changes to the SDK and/or the platform.

For now, is it feasible to maintain the subscriptions necessary and force resubscribe from your application logic?

We could do that, however a concern is the following:

• It looses connection every couple of minutes. Could you please look into this? (i.e: not disconnecting so often)

Thanks
