Subscriptions - delayed

[CameronTurner]

I find when using the below config, the particle device is:

• More stable (less restarts/lockups resulting in the watchdog kicking in)
• Can flash OTA (would previously not be able to complete an OTA flash)

However, the downside appears to be very delayed (or lost messages) from subscriptions.

• Some subscription messages are lost
• Some subscription messages arrive 3-4 minutes later.

Is there a way to separate out receiving any publish events from the other activities that might be 'blocking' OTA capabilities in the below?

Code

MQTT client("xxxxxxxx.iot.ap-southeast-2.amazonaws.com", 8883, 360, callback);

//The below code is run every 120 seconds
            if (client.isConnected())
             {
                 client.loop();
             }
             else
             {
                 if(awsDisconnect == 0)
                 {
                   connectToAwsMqtt("connect");
                 }
             }

check your firmware source code about the OTA(0.6.x/0.7.x/0.8.x) and network packet with WireShark.
