Had a rather similar idea back in 2014 when I was still in college for my networking course semester project. Made a simple app using BLE 4.0 on swift 2.1 (I think? Forgot) that’s able to do P2P or broadcasting relying on device to device message relay. Connection network topology was defined as a tree instead of a cyclic graph due to the limited number of BLE connections allowed in iOS under high density devices circumstances. Later I learned that BLE 5 started to support mesh network. I don’t know how similar it is towards what we’re trying to do here but I’d love to learn more. Unfortunately for my project I wasn’t able to refine it further. But with that said. I’d love to learn about how Berkanan SDK is structured and designed and possibly contribute to it. Nice work!

Dear Bluetooth developers,

I want to change the world for the better.

I'm the developer of Berkanan Messenger ( https://apps.apple.com/us/app/berkanan-messenger/id1289061820 ), a Bluetooth-powered mesh messaging app — featured by App Store editorial.

My goal with Berkanan Messenger and Berkanan SDK ( https://github.com/zssz/BerkananSDK ), the framework that empowers it, is to create a decentralized mesh network for the people, powered by their device's Bluetooth antenna. People could rely on this network for texting in situations, like emergencies, when there's no other connectivity available — it could literally save lives.

I kindly invite you to join this cause and to contribute to Berkanan SDK with your code, comments, ideas. Even a simple gesture, like giving it a star on GitHub, helps:

Spoiler: It's *not* a Bluetooth Mesh Networking implementation ( https://www.bluetooth.com/specifications/mesh-specifications/ ).

Thank you for your attention. Hope to see you over on GitHub!

Sincerely, Zsombor
