WLED: ESP8266 Exception 28 (Adafruit Feather Huzzah)

What a great project! I’m coming over from the McLighting V2 project, trying to find something I can use standalone without relying on a WiFi signal (for our tent lights when camping), and discovered WLED00…

I’m running into an issue though. I’m using RGBW WS2812b LED strips. When flashing the OTA Updater sketch first, then uploading the pre-built 0.5 BIN, the units work beautifully, except for the coloring on the strips. The 0.5 image does not seem to support RGBW, or at least I can’t find a way to specify the LED strip in the documentation or the sketch…

When I build the sketch myself, I leave everything as default except the SSID/PW for my home wireless (for my test units here), and enabling the serial debug.

I receive a constant Exception 28 reboot within half a second of the unit connecting to my wireless here at home.

Dat Mobile UI… ლ(▀̿̿益▀̿̿ヽ)ლ

The unit boots without the boot loop or crash, and I am now able to successfully install and configure it. Very excited to see where this project goes. I have SmartThings in the house, and would love to integrate these into the theater accent lighting… Having the lights change sequence/color as the movie experience in the theater progresses through trivia, trailers, etc will add a touch of “HOLY SH**” when people come over.

Thank you for such a prompt response and fix!

Ah HAH! I don’t think I knew what the arrows meant in relation to multiple units.

I’ll test the dev branch out once you update it and confirm it is resolved on this end before you make the 0.7.1 push. 😃
