Meshtastic #2171

Description of the feature you're suggesting.

I see that someone has already worked out how to do LoRa/Meshtastic using an SDR. See https://gitlab.com/crankylinuxuser/meshtastic_sdr - it’ll work with a HackRF.

What are the chances of porting this to a Mayhem based Portapack as an app on the SD card? That would be so cool…

Anything else?

No response

I think the chances are based on how popular is the idea to get enough people poking on it, but it could start with one :)

I will note that in the article they created that nice Gnu Radio script and then said;

We only need to throw CPU at the problem.

Easy for a PC but the Portapack does not have a lot of spare CPU. That being said, we have a pretty amazing team 👍

The CPU part is mostly because it can decode all 8 LoRa presets at the same time and even up to all of 900MHz ISM spectrum for all LoRa channels which then needs more CPU to decode everything at the same time and Real hardware can only decode the preset in which its set to. so it would be less of a problem.
