OpenThread, Useful? Pratical?

While reading another post I noticed this gem:


Thread® is an IPv6-based networking protocol designed for low-power Internet of Things devices in an IEEE 802.15.4-2006 wireless mesh network, commonly called a Wireless Personal Area Network (WPAN). Thread is independent of other 802.15 mesh networking protocols, such a ZigBee, Z-Wave, and Bluetooth LE.

I’ve been noticing posts that touch on a number of ideas, often in long threads that have wandered beyond the original topic (scope creep). So I figured I’d occasionally dig something out and start a focused discussion to see how useful, and how practical something may be as well as see what kind of general interest t has.

So, OpenThread. Could it be the One Mesh (The one ring to rule them all ref) that could allow some form of interoperability (especially as an option) of different projects?

One thing that helps is that the rest of meshtastic tries to be pretty agnostic on what the actual transport is at the bottom.

I initially looked at qmesh and reticulum and they both looked really cool but also still pretty ‘alpha’. I also looked a lot at but its implementation was super power inefficient and not really designed with off-the-shelf radios in mind.

So for our current transport: I initially used the mesh router that was part of RadioHead. Then I added flood routing and substantially lowered battery consumption (by letting the main CPU stay in light sleep). Later - for more support for more radios, I changed the phy layer to be based on RadioLib rather than RadioHead.

If someone wants to do the evaluation and effort to port our transport to use qmesh/reticulum or openthread I think that would be great. My personal queue of tasks (nearterm: more devices, multi channel support, mqtt, global messaging gateway and store in forward messaging) are more in areas that are ‘above’ the transport layer.

For the current (and nearterm - next six months?) usecases I suspect the current transport is adequate, but eventually we will want something better.
