A bit different, as it's mainly for voice - but I made an app 'Murmur : Bluetooth Group Calls' - that lets you hold group voice calls and message via a mesh of Bluetooth LE connections. It's available on Android and iOS. https://apps.apple.com/gb/app/murmur-bluetooth-group-calls/i...

Doesn't really get any downloads, so not sure there's much demand for this - but I use it with some shokz bone conducting headphones for talking to my wife when we're cycling (also for wrangling our two small girls)

Cool technology, but what is the usecase? I can imagine traveling abroad without a sim and using it as described. But is it any better than using the cellular network (when you have access to it)?

On festival sites and other crowded events, cellular sometimes gets quite saturated and slow. This might be a good alternative.

Also, I could see it as a useful tool in emergency situations. But a lot of people would need to use it to be actually useful.

When I last had a university workshop where 20 people in a room worked on a bluetooth protocol I also noticed bluetooth is quickly saturated with many participants. Hopefully that changed in the last 15 years since...
