Yep, useful docs for sure @Gualtier Malde – I came across those already. It seems the RN implementation is the challenge I was particularly looking to solve, and seeing how I can call those methods from React Native, or design the native code correctly and then expose those methods to my React Native via RCT_EXPORT_METHOD (I'm not familiar with native iOS programming, so while I understand the docs in principle, I'm quite confused as to how to go about implementing that, and what methods I need to create & call from my React Native code base). Any guidance on the specific implementation would be helpful. I know I have to use CBCentralManagerDelegate, and specific methods like peripheral:didDiscoverServices:, but I frankly have little idea on how to use those in context, so I'm trying to figure that out.

Did you manage to figure this out? I'm having a similar issue, where I can't rely on didDiscoverPeripheral to detect a device in background and trigger a callback that I have.
