wifi sleeps after 30 mins and restarts itself.

[Trialblazer47]

I am testing a example code for MQTT https://github.com/tuanpmt/esp32-mqtt and it works fine for a while but after every 30mins the devices does something that is not in the code. here is the debug message.

Code: Select all

[MQTT INFO] MQTT_MSG_TYPE_PINGRESP
[MQTT INFO] Sending pingreq

[MQTT INFO] MQTT_MSG_TYPE_PINGRESP   <----------till here working fine

I am not sure if its okay to have this behavior.
