+Subject: [PATCH] Increase keep-alive interval
+
+The MQTT server resets connection if the device doesn't send keep alive
+packets within keep-alive interval, which is configured to 5 seconds by
+default. Increase the keep-alive interval to 60 seconds to avoid connection
+reset request when the device is busy.
