Environment

  • IDF version (run git describe --tags to find it): v4.0-dev-779-gbeff4adc7
  • Build System: Make
  • Compiler version (run xtensa-esp32-elf-gcc --version to find it): 1.22.0-80-g6c4433a5
  • Operating System: Windows
  • Power Supply: USB

Problem Description

If the MQTT client was unable to connect and esp_mqtt_client_stop() is called, an exception is thrown.

Expected Behavior

esp_mqtt_client_stop() should be able to handle the case where the client was never connected.

Background

I am attempting to support static IP addresses. I accidentally misconfigured the DNS server and as a result the ESP32 was unable to resolve the domain name for the MQTT server.

Debug Logs

E (11246) esp-tls: couldn't get hostname for :[MQTT server address]:
E (11247) esp-tls: Failed to open new connection
E (11247) TRANS_SSL: Failed to open a new connection
E (11253) MQTT_CLIENT: Error transport connect
