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)?

I would love to use it to talk to my girlfriend when we go bike riding. I was shocked by the price tag for all the motorcycle helmet comms systems.

If you're looking at the premium segment then yeah, when you're going out with your several mates and need to be able to hear every one of them.

For one rider to one rider you can get a very decent set well under $100 (Lexin b4fm, FredConn, even Thokwok is well reviewed).
