microbit-dal VS Home

How are you programming these devices, and are you using the compass calibration algorithm that's built in? (the micro:bit will say "tilt to fill screen" and then require you to fill the screen by tilting the micro:bit - if that's happening then you're using the calibration). The magnetometer is very sensitive to nearby magnetic things like the batteries and other micro:bits. If you aren't connecting the battery to the device, or have the cable plugged in in a fixed position, those things could also be affecting the magnetic field. Here's some past debugging before the calibration algorithm was improved https://github.com/lancaster-university/microbit-dal/issues/288.

https://www.nanoframework.net/ not sure how it good in current state but for those who want use c# on esp32 - its reasonable way)

check out https://www.nanoframework.net/

You can do embedded with C#, you can work on microcontrollers, and you can make games in Unity.

Arduino, but runs .Net. https://en.wikipedia.org/wiki/Netduino Nano framework let's your write c# for esp32 and whatnot. https://www.nanoframework.net/

Yeah, that's my first thought. I've done some ESP32 programming and tried out nanoframework as my first attempt. Nanoframework is a cool project but I had some problems and ended up having to write everything in C.

Well, there is https://www.nanoframework.net/ though microbit isn't supported, but ESP32 is
