Hi Sam,

Thanks for contacting us.

I'm not sure I can speak too much to the routing, but we do have a network simulator written in Python, that you can play with here, and the code is available here.

The main problem I see with MDP is that it is a Layer 3 protocol. I know we are not using the LoRaWAN Layer 2 protocol and only using the physical layer LoRa modulation scheme. Also, we are concerned about bogging down the network with too many acks and re-transmissions. Not sure if @juul or some of the SSB people might have more to say about possible routing schemes.

As for the hardware, we only have a few prototype boards that had some minor problems. Once we finish the updated design, your best bet is to probably get your own printed, as we have a number of people in Oakland and NZ waiting for boards. The KiCAD schematics are available here, though you should wait for @nanomonkey to tag another commit.

Happy holidays!

Hi I'm Sam

I was involved in the now defunct http://www.bristolwireless.net/about-us/ for about 10 years, more recently I helped start The Things network in Bristol. I was thinking about hacking together one of these: https://github.com/dmahony/Lora-Chat-Device

When I found your project :) I'm curious how you're handling routing?

Could the Mesh datagram protocol from Serval be any use to you?

Or is it too heavyweight for the LORA side?

I also read on your mailing list that you've had a few boards made up, would you consider shipping a couple to the UK?

Thanks

Sam
