ESP-IDF MQTT example

[alexey_powers]

So Im trying to launch an example of MQTT client (mqtt/tcp example). And constantly getting an error :
MQTT_CLIENT: Error transport connect. Is there something Im doing wrong?

Code: Select all

manage to find a problem. My MQTT-server host had a firewall, so connection was rejected...
