ESP8266 fw: v2.2.0.0 or v2.2..1.0 connect to the same MQTT broker. send MQTTCONN , response : ready look like ESP8266 restart again? Inked微信截图_20210916164608_LI

in fw v2.1.0.0 works well. Inked微信截图_20210916211400_LI

@edieruby ESP8266 is not recommended as the preferred choice for MQTT connection over TLS, due to the relatively limited memory, and ESP32-C3 is recommended instead. You can use AT+SYSRAM? command to query the minimum available memory.

According the log you provided, it seems to be a stack overflow issue. For a test, you can try to enlarge mqtt_task stack: ./build.py menuconfig-> Component config -> ESP-MQTT Configurations -> MQTT task stack size.

[16:31:53.189] AT+SYSRAM? +SYSRAM:45512,42160 OK

the memory is not enough? my same code can run in v2.1.0.0 maybe it's a BUG? @ustccw

same to https://github.com/espressif/esp-at/issues/568

edieruby commented 3 years ago

not the same issue. This means EPS8266 in V2.1.0.0 can connect to a MQTT broker by TCP over TLS , but ESP8266 in V2.2.0.0 or V2.2.1.0 can not connect to the same MQTT broker.

[09:46:40.326] all parameters are ready [09:46:40.375] Stack canary watchpoint triggered (mqtt_task)

I had the same issue when I was trying to do HTTPS requests. This error means that task stack overflowed because default stack size is too small for SSL. You should try going to menuconfig -> 'Component config' -> 'ESP-MQTT Configurations' -> 'MQTT task size' and increase it. My issue got resolved when I increased AT task stack to 4KB.

yes, i mentioned it at https://github.com/espressif/esp-at/issues/566#issuecomment-921581129.

All in all, ESP8266-AT should not used for MQTT over TLS, otherwise, the product is always with risk. User should consider the ESP32-C3 instead of ESP8266 in this case.
