Basic example crashes when wrong port is set (1880 where node-red is running).
Today while testing the "FullyFeatured-ESP8266.ino" example, I made a mistake and instead of using port 1883, I set 1880 where my node-red is running. The program crashes:
Connecting to Wi-Fi...
Connected to Wi-Fi.
Connecting to MQTT...

<<<stack<<<
When I set port 1883 it works. When I also set any other not used port, it normally disconnects.
Port 1880 is the web interface of nodered not the MQTT port so that is why...
The crash should not happen, but it in normal situation it will be fine...
The crash should not happen, but it in normal situation it will be fine...
This crash happened in my application and I couldn't find what was wrong until I noticed the wrong port. Then I run the basic example to be sure that was not my code's bug. I hope this to be fixed soon.
Is it possible to decode the stack trace? I'm quite interested in how this happens. I can't reproduce.
