ESP32 panics if WebSocket doesn't exist
Nufflee opened this issue · 5 comments
My ESP32 panics when I try to connect to a WebSocket that is not running. This is not what I'd expect, I would expect it to try connecting and if it fails it just tells me that it failed and doesn't make the ESP32 panic.
Everything works as expected once I start the WebSocket.
This issue is closely related to #10 but the conclusion you've come to in this comment is that it only happens when there's not a working WiFi connection but it also happens if the WebSocket is not running.
This is the full panic message:
[E][WiFiClient.cpp:282] setOption(): fail on fd 54, errno: 22, "Invalid argument"
[E][WiFiClient.cpp:365] write(): fail on fd 54, errno: 104, "Connection reset by peer"

Rebooting...
Thank you, I will look into it and let you know what I found out.
Gil.
Can you try version 0.4.9 and tell me if its working as expected for you?
This is just a bug with WiFiClient
most probably, but I found an interesting way around it. Also this gives me some ideas about tests I should have to make sure it's not me using the library (WiFiClient) in a wrong way..
Thanks,
Gil.
This is basically the same workaround I did myself after a bit of debugging so I'm pretty sure it would work. I will take a look tomorrow and hopefully remember to report back.
Thank you for the quick response!

Cool. Notice also that I've opened an issue on the Arduino-Esp32 project espressif/arduino-esp32#3056
They say it was resolved and will be pushed in the next release.
Hopefully they will fix that soon.
Gil.
Can I mark as resolved?
