Absolutely not : Lilygo T-TWR is an analog radio.

Yeah, if you use something with this sort of bitrate you might as well use one of those codecs, but I think it would be nice to have more range rather than a high bitrate.

That said, you can get pretty good quality on FRS if your radios aren’t crappy, which most of them are. The same FM parameters normally provide a clean, very readable voice with other (e.g. amateur) radios. Even the cheap chinese ones you’d expect to be worse. Maybe the handhelds made for GMRS would be better? Or MURS. And especially the latter two can easily go miles if done right. Or maybe there’s at least one FRS handheld that has actually improved over what we had 10-20 years ago, but that’s probably too much to ask.

Unfortunatly, the ESP 32 doesn’t have a FPU so it is a bit complicated. And then again, my coding skills are not up to snuff…

ESP-NOW in long range mode can do around 500m

So the microphone and speaker in it are completely non-functional?
