Bluetooth can provide contact tracing, even between strangers. Instead of requiring thousands of healthcare workers to do contact tracing manually (as is the current approach in China), the process will be cost-free. We plan to build an iOS app that respects the users' privacy and works even in the background. Quickly. Question: Is there any way to enable service discoverability between two background-running apps on iOS? Currently, it works between two foreground-running apps, and between a foreground-running and a background-running app, but not between two background-running apps. Combining this with the background significant location change API might help a little, but we're afraid it would miss a fair number of contact events. Looking forward to your feedback, Zsombor _______________________________________________ Do not post admin requests to the list. They will be ignored.

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!

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: https://github.com/zssz/BerkananSDK Spoiler: It's *not* a Bluetooth Mesh Networking implementation ( https://www.bluetooth.com/specifications/mesh-specifications/) Thank you for your attention.
