How to use watchdog with blocking MQTT calls in Zephyr?

[pawankumar0099]

I am using Zephyr MQTT client, and functions like mqtt_input, mqtt_live and mqtt_publish are blocking.
I want to enable the watchdog, but I am not sure where to call watchdog feed because the MQTT loop may block for a few seconds.

My questions:

1. How should I feed the watchdog when MQTT API blocks?

2. Should I create a separate thread only to feed the watchdog?

3. Is there a recommended pattern for using watchdog with MQTT in Zephyr?

I think you can use the subsys task_wdt
