[Xastir-dev] LORA and interfacing

[Steve]

I gave two of the TTGO units including a couple of Rnodes.

I’m going to try a couple of the existing firmware options out there. Some
are KISS based some are not. I like the possibility of using the wifi or
Bluetooth with the TTGO with some of the APRS programs fir the phones.

Seems for a mobile device, not have a extra board such as a PI might be
nice… we’ll see!

The TTGO can also be used for this:

The Rnode guy is also implementing a MESH system but is only in the alpha
stage. Beyond my ability.

I’ll have to get back to you on Freq, I only got my TTGO going last night
and didn’t bother to look!

There is a LORA APRS group on Facebook, grin, that is mostly from Europe
who have a lot of experience with this .
