@lukipuki Thanks for working through the bluetooth discovery! This MR is just to keep track of these changes, hopefully we can get things merged up in rust and this MR will need to be updated

@barkincavdaroglu Thanks for looking through. for some background, this is a placeholder PR until https://github.com/meshtastic/rust/pull/66 is merged, then this should be switched back to the official rust repo at head.

Can you try this new API instead https://github.com/meshtastic/rust/pull/68 ?

I'm also considering to swap out the tuple to a 2-field struct with name: Option<String> and mac_address: BDaddr. It would be great to hear your thoughts on that.

Hi all, I am no longer a maintainer of this repo. I worked on this as part of my college senior cumulative project. I understand the repo got significantly larger now and I also like that more people are contributing to it. However, I no longer have enough context about the code in this repo so all major changes should go through @ajmcquilkin
