Hi, Sigfox has recent launched in my City (Lima, Peru) with a local partner, They have a (limited) free plan, I would like to test but I don't have any board compatible with Sigfox. The local Sigfox partner promises total coberture in all city (if no, you can request and they will put a new antena xD they say).
Any option to apply to a
Pycom Fipy or
Pycom LoPy4 ?
I promise, as usual, record a video showing my results and giving credits to Seeed

Regards
