@Steve_Anken sounds cool, looking forward to seeing what you come up with! 
@Jason_Coon , it may be a while. Too much to do and soon to be overwhelmed. It will get done by someone. The ESP32 is just starting to get legs. The audio stuff is coming along too so it’s just a matter of time before people realize how much this board can do besides run LEDs.
I am looking into adding a MIDI extension to App Inventor. MIDI has a lot of potential for coordinating LEDs and other things besides music. It’s too bad so few seem to realize how important MIDI is to musicians and what it can do. Android Studio is nice but all this is a time suck so it only gets done between other things.
Following along intently. This will be a welcome addition to the 15m string of WS2812’s I installed around the perimeter of our outdoor deck last year. Currently when I want to change colors or patterns, I bring the microprocessor inside and plug it into my PC to load a new sketch. I was looking at a set of XBee’s to upload sketches wirelessly but the ESP32 seems far better. Thanks for leading the development efforts Jason!
ESP32 Bluetooth library about to be merged with main Arduino core and it can be used with the existing BLE code. Now to see how to do both with App Inventor.
Just pushed an update, fixed twinkles crashing with more than 255 LEDs, fixed an error setting a solid color, parallel output support, etc: https://github.com/jasoncoon/esp32-fastled-webserver/commit/8b8cbbfe8da9975b1845d45de6c8af85157c027e
@Jason_Coon I’m trying to add a dynamic colour pallette generated from accelerometer data.
I’ve added it to the list "const CRGBPalette16 palettes[] " and to "const String paletteNames[paletteCount] " in palettes.h.
It comes up on the list on the webpage, but when I select it, the patterns fail to pull the colours from it, they just get black.
If I hardcode it into a pattern, replacing “palettes[currentPaletteIndex]” with the name of the dynamic palette then it works. I must be defining something incorrectly somewhere, I’ve tried everything I can think of, but can’t find a fix…
Do you have any ideas?
Thanks
@Jason_Coon I’ve worked it out
I just had to declare CRGBPalette16 palettes[] as a variable rather than a constant. Slightly embarrassed about how long it took me to realise…
@Jeremy_Spencer sorry, I completely missed this somehow! Glad you got it working, though. Good to know!
I was able to get eps8266 working and tried getting esp32 working. Esp32 loads and leds display. What browser address do I load the page on? It connects to my home wifi but when I try 192… that was used on the 8266 code, it won’t load. I tried setting it up as an AP mode also and it wouldn’t compile. Super excited to get it working. If I can help with anything I’d love to.
@Chris_Stock Your router will always try and give individual devices a different IP address. Add these lines to web.h after “webServerStarted = true;” (line 70)
Serial.println();
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
Then the IP address will be sent to the Serial Monitor.
Gah, that should be included in the sketch, I’ll get it added, thanks!
Awesome thanks I’ll check it out.
For some reason I am getting Not found: /
Could be user error. I have the esp8266 sketch working. When I use the esp32upload tool it is taking only 4 seconds which seems too fast. The esp8266 upload tool took several minutes to upload.
Ive tried getting AP mode working also and keep getting reboot error. Is Ap mode working on esp32?
@Chris_Stock , I don’t think AP mode is working properly with SPIFFS yet.
Have you followed the SPIFFS fix instructions in the readme?
Which version of the ESP32 Arduino core are you using?
After installing all the requirements (including forked libraries) I get this reboot loop:

"Guru Meditation Error: Core 0 panic’ed (Interrupt wdt timeout on CPU0) "
Looks like a Watchdog Timer (wdt) error.
Have you got a delay running somehwere?
I’m successfully running a few variations of this, but can’t remember all of the changes…
@Jeremy_Spencer I am getting the same error right now
Fresh Esp32 install.
Guru Meditation Error: Core 0 panic’ed (Interrupt wdt timeout on CPU0)
Core 0 was running in ISR context:
EPC1 : 0x4000bff0 EPC2 : 0x00000000 EPC3 : 0x00000000 EPC4 : 0x40081709
But it seems to run fine for a little, without the Serial monitor hooked up. and just running?
