[ESP32 mqtt-client] Print No PING_RESP, disconnected
Posted: Fri Aug 18, 2023 2:40 am
Hi everyone
My mqtt-client will always issue a ping request but fail to receive a ping response,
resulting in repeated disconnection of the device.
Is there any solution to this problem?

My mqtt-client will always issue a ping request but fail to receive a ping response,
resulting in repeated disconnection of the device.
Is there any solution to this problem?
