I would like to have an application that shares files with my friends Flipper Zeros by Bluetooth without much work on my part. It would work like this:
- My friends and I share our Flipper Zero Bluetooth addresses (BD_ADDR) with each other.
- While we are apart, we put files to share in a special folder on our Flipper Zeros.
- When I meet one of my friends again, our Flipper Zeros recognize each other by BD_ADDR and exchange files.
- Our Flipper Zeros notify us when we receive new files.
I once worked with an Android app that had this feature. It was for viewing and extracting files embedded in satellite broadcasts. https://knapsackforhope.org/
