Update on LoraMesh

[chadtfraser]

Hi @catalin

In one of your earlier posts on the launch of the new LoraMesh Support, you mentioned that you are targeting mid-august for an update. I am very excited about seeing a full example of a thread mesh running on pycom devices border router and all. Any idea of when the update would be ready. I am very new to mesh networking and hardware programming in general so a complete example would be very useful.

Best Regards

Everything's clear now, thanks again.

@morpheus, we will have Pygo releases (stable or development) only when Pygo will be available to users.
But for Lopy, we'll have a stable RC release pretty soon, this won't contain Mesh updates. Probably in the next Lopy dev. release I will update Mesh feature.

I hope I am clear now, so we should not mix (yet) Pygo and Lopy releases.

@catalin
So the stable release can be expected along with shipping of the pygo-pledges?

@morpheus
Thanks for reminding, I've forgotten about encryption, another team-member is working on it. Maybe we'll have it end of the year, too.
I would wait for next development release, honestly I didn't pushed Mesh modifications on the release repo, since ~August :( my bad. Now I've just updated openthread to the latest and testing some features.
Fyi, most likely, we won't add Mesh feature in the stable release, yet.

Thanks for your fast reply!
Sounds promising :) i'm planning a mesh field-test with 5-10 nodes maybe i should wait for the next release.
What about encryption? Is it already implemented? I didn't see anything about it in the last dev-release.

hi @morpheus,
The road-map is based on Pygo developement, which, of course, will be included in the Lopy/Lopy4 releases.

I could update on forum periodic updates.

For now, I am trying to minimise devices time to join a mesh, and to maximise number of devices in a mesh network. Also I've developed a protocol inside mesh, so every node is aware of all the other nodes that are in the mesh (MAC, IP, properties(GPS coords if they have pytrack), radio direct-link connections).

Next, some collision detection/avoidance mechanism will be added at Lora level.

Afterwards, Border Router functionality will be offered using all our other network interfaces (bluetooth, Wifi, cellular).

I target these 3 hot-spots to be done until 2018 end (pretty optimistically).

hi @catalin,
is there a road-map somewhere for the mesh-development?
I'm quite exited what will be possible with a Lopy and Pygo network!

hi @chadtfraser
Thanks for you interest into Lora Mesh.
Honestly, lately we were quite busy with the Pygo development, and I did not have time to prepare a release with updated Lora Mesh. As usual, all work will become open-source for our community, at some point.
For now, you could simulate a Border Router by having an UDP port open on the designated BR (like a server), and send all Mesh traffic to this BR. Next, the BR would repack data for Wifi/Cellular/BLE.
Sorry, for not respecting the targeted release date.
