How many nodes can be involved in the same PAN?

Hi there, How many nodes can be involved in the same PAN? i can't find the data, anyone can tell me?

Well, there is little experience with Flutter systems, of course. We are all waiting...

In general - it depends on the quality of the system, the size of the network, position, topology, and amount of traffic, and the type of networking.

I do know of industrial systems who are getting 3000 of nodes working using 900Mhz radios. But they are using commercial software, tiered networking, and extensive tuning. They have multiple gateways that provide IPv6 connectivity from a central server to individual nodes.

Then there is the open-source OS that uses IPv6 and 6LoWPAN called Contiki

Of course - there is also the ZigBee technology which is not TCP/IP based.
They all have different characteristics.

Thanks grymoire. What's the Flutter's mesh protocol? anyone knows? is it possible port Contiki os for Flutter?

I'm not sure how it meshes. I do know Taylor would like to get Contiki on it.

Yup, Contiki is on the bucket list. It seems very mature and should be an ideal match for commercial customers looking to use Flutter's awesome hardware with something proven.

Our protocol is all willy nilly. Right now it does star topology and we will add star of stars next. Then some kind of meshing would be the real goal, naturally. We do expect to get there because we have so many talented people in the community who want to help.

But Flutter's hardware is capable of whatever might be needed to get thousands of units working in one network. I have lots of ideas here too, but will wait until I can develop it with the community.
