Hello,

for my school project in high school, I am making true wireless earphones, but pretty struggling with their pairing.
I am lost in two factors, such as how does they both simultaneously connect to your phone, laptot etc.
and what's the best solution for the start of pair cycle (like when opening the charge case, button on earpad etc.)

Can someone give me hope on this?
Thanks a lot for your time!

I mean, I am doing myself a whole new PCB. Without any modules etc. Just from scratch.
