that was basically Rumble an app I developped 10 years ago: https://github.com/Marlinski/Rumble

I worked the field both academic and startup, I even made one of the first implementation of the Bundle protocol for store carry and forward (IETF transport protocol for the deep space network RFC9171).

Turns out the Mobile OS are making this kind of communication nearly impossible. To work well, it basically needs background job (automatic scan of nearby ble/wifi/radio) and automatic connection without user interaction (imagine being prompted to accept a connection every time you pass by someone), both have been basically made impossible (especially after covid).

Isn't this how some covid-specific apps work to let you know if you've come in contact with an identified carrier? https://www.gao.gov/blog/covid-19-exposure-notification-apps...

They relied only on scanning nearby id-s, without communication.
