In fact, my team have released several open source projects for RAK833 as follow:
- This is used for RAK833 + RPi:
- This is used for RAK833 + MT7628 + OpenWRT:
- This is used for RAK833 + SolidRun + Debian:
- This is used for RAK833 + SolidRun + Yocto:
I think maybe these projects can be used on RAK2247 too.
BTW, there is another project for RAK833 + RPi which is a Docker solution. It is developed by Microsoft.
Maybe, it can be used for RAK2247 + RPi too, just try it.
