ESP8266 Runtime exceptions(would cause restart) with OMG when MQTT broker stopped

lkisme · September 18, 2021, 3:45pm

Hi there,

As I mentioned in this thread

ESP32 BLE gateway dying every X days - #107 by lkisme

I am facing OMG dying issue and want to resolve it, so I used the “screen” command to connect one of my ESP8266 device with OMG firmware, and found out that sometimes the OMG would throw a exception, which may be one of the root causes.

The decoded messages are the same:

Exception Cause: 28  [LoadProhibited: A load referenced a page mapped with an attribute that does not permit loads]

I managed to reproduce this issue on 2 of the devices, here are the procedures to reproduce:

Simulate “MQTT_CONNECTION_TIMEOUT”

I used a ESP-wroom-02(ESP8266 + 2M flash) chip and the code change is here :GitHub - lkisme/OpenMQTTGateway at ibox
Start a mqtt server on a computer in LAN, add a breakpoint on the line of process the “Connect” request to simulate a “mqtt connect timeout”
Let OMG use the broker we setup at step #2

here is the original exception output:

W: failed, ssl error code=2555905
W: MQTT connection...
W: failure_number_mqtt: 3
W: failed, rc=-2
W: failed, ssl error code=2555905
W: MQTT connection...
W: failure_number_mqtt: 4
W: failed, rc=-4

Simulate “MQTT_CONNECT_BAD_PROTOCOL”(MQTT_CONNECTION_TIMEOUT wouldn’t cause exception on this board)

I used a NodeMCU v3(Lolin) dev board and the code change is here : GitHub - lkisme/OpenMQTTGateway at 8266-098
Start a mqtt server on a computer in LAN, and the broker doesn’t support mqttV4 protocol.
Let OMG use the broker we setup at step #2, then wait a moment, the exception will be thrown at the third time it failed to connect to the broker.

Hi,

Thanks for taking the time to isolate and give details, this seems to be related to an out of memory error?

I’m suspecting a memory issue with ZgatewayRF or RCSwitch.
I push your code to a NodeMCU and will let it run several hours.

lkisme · September 19, 2021, 12:29am

In my case, it seems related to the bad condition of WiFi connection to connect to the mqtt broker, so I assumed it may be some problems with pubsubclient? Anyway I’m not expert on C/C++.

FYI, I used this project (GitHub - shimonxin/light-mqtt-server: A lightweight MQTT server)to simulate the mqtt connection problem, although you may need a Java/maven dev environment to run it. with controlled mqtt broker, you don’t need to wait hours.

1technophile · September 19, 2021, 3:03pm

Do you reproduce the issue with the unmodified OMG code ?
Just by using a PIO environment like this one:

[env:nodemcuv2-rf]
platform = ${com.esp8266_platform}
board = nodemcuv2
lib_deps =
  ${com-esp.lib_deps}
   ${libraries.rc-switch}
  ${libraries.esp8266_mdns}
  ; ${libraries.unifiedsensor}
  ; ${libraries.dht}
build_flags =
  ${com-esp.build_flags}
   '-DZgatewayRF="RF"'
  '-DZactuatorPWM="PWM"'
  '-DZactuatorONOFF="ONOFF"'
  '-DRF_EMITTER_GPIO=5'
  '-DRF_RECEIVER_GPIO=4'
  '-DMQTT_SERVER="ha.cn"'
  '-DGateway_Name="OpenMQTTGateway_ESP_02"'
board_build.flash_mode = dout
upload_protocol = espota
upload_port = 192.168.3.239
upload_flags =
  --auth=OTAPASSWORD
  --port=8266

And having the original v0.9.8.
Note that I have combined your configuration into one platformio environment.

lkisme · September 20, 2021, 2:21pm

Yes, the issue is reproducible, and the decoded message is the same.

Here is what I did:

Checkout a new branch from the tag 0.9.8.
Change the platform.ini like you wrote, then compile
Flash the nodemcu(Lolin) with the firmware built at #2 by using NodeMCU PyFlasher(Mac OS version).
Config wifi info & mqtt broker address(192.168.3.82) in wifimanager page.
Start the Mqtt server at my Mac(192.168.3.82), and simulate “connection timeout” and “connect failed”

Yes, I simply added the if condition around the ssl error log print sentences like your diff, with the if condition avoid the ssl error log to print, the exception disappeared.
