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)

Okay, this is neat! A true mesh networking bluetooth app- The other one that's notable, Briar is super impressive - but i think it doesn't actually have proper mesh capability due to difficulties with how devices handle things

(See: https://old.reddit.com/r/Briar/comments/gxiffy/what_exactly_...

Anyway, -Question: I take it Murmur is end to end encrypted fully? Also, just curious if this is open source?

This could become SUPER useful- having a actual mesh networking Bluetooth app , if it's open source/E2EE!

It's AES128 encrypted with a key derived from the group password.

I'll try this app because Briar never worked between any of my devices (all Androids)
