I think I might be going to be sick …
At a technical level, the engineering work to port software over to do that would be huge.
And the PyCom or even the TTIG is about the same size if you want to go compact. And the price differential between them & a GNSE makes any attempt to port the software over economic madness.
I speak as someone who
- Knows the GNSE software
- Knows enough STM32 to sleep badly at night
- Have poked around the inside the Voldermort code base
- Values his time far more than the mess of dealing with borking devices to only know 1 frequency at 1 SF
If you were going to do anything, take the existing gateway design in KiCad that’s on the forum and make it your own - then you can get the size down & you cut out all the middle-people that charge minuscule amounts of money for the joy of Pick & Place etc etc
