Please try this build:

https://www.espruino.com/binaries/travis/wilberforcepatch11/espruino_esp32.bin

You should see v3.0.3:

>ESP32.getState();
={
  sdkVersion: "v3.0.3",
  freeHeap: 37848, BLE: false, Wifi: true, minHeap: 34612 }

You might also need to load the partition table.bin as this was changed going to v3.0x

I know there are alot of other priorities in this great effort you and JumJum are doing. I am curious what the change was with adding the Bluetooth code.

We moved from the 2.x esp-idf to the 3.0x esp-idf. This changed a lot around Makefiles and things. We have no clue to why the neopixel code that was working with 2.x is not working with the 3.0x libs.
