I got a T-deck for my PDA project and decided to get one with LoRa because, why not. Then I got a Heltec Lora32 v3 and Cardputer for Xmas last year.  

I'm been busy trying to start my game studio so haven't had much time to work on it but the 2 years I'd given to starting it are finally up. 

This year I'm getting a few of Circuit Digest's LiteWing drone to experiment with autonomous repositioning to improve the new work coverage and data ferrying.

I found out just how slow LoRa is and how small the MTU is.  I know the numbers, but I don't realize the practical significance of them

We attached a finder to the remote we keep losing, it wasn't a bluebooth one but it got me interest in those Bluetooth beacons like the Airtags.

So I learned some about Bluetooth to find out if you could make your own app for them.

So looking into it, It shouldn't be that hard to make scatternet out of Bluetooth/WiFi the device would operate as WiFi AP/Bluetooth Peripheral and when a node wants to send data to it, it connects.

This means it would be point to point and not broadcast like I wanted but with the higher data rates it should be a problem.  

I'm not sure about how Ergonomic it'd be. I think on android the user just needs to accept the connection once then it will allow it to connect to the device again. but I'm not sure.  

Even it is a PITA, it would still allow you to connect to the network with an ordinary phone.

and it should be work perfectly on Linux computers and nRF52, ESP32s.

on the protocol front I was thinking of the network make a Minimum Spanning Tree to give nodes a topological coordinate but then I heard about Minimum Diameter Spanning Trees and realized that what I really wanted. 

We can use the Spanning Tree to reach any node from any node, now I'm looking into ways to find better paths between nodes

Right now, I'm thinking about each node keeping track of all the nodes that it can reach by 2 disjoined paths

I'm also considering some sort of hierarchical clustering-based routing.
