We wanted to find a new alternative to Bluetooth for info transmission
What it does
It transmits byte code between devices through frequency key mapping, and we wanted to have it work through Apple watch
How I built it
We built it by creating a sound file that would be synced to a file, and have a receiver on the other end.
Challenges I ran into
We found a race condition big in WatchOS2, so we failed to play a file from the apple watch.
Accomplishments that I'm proud of
Saving the buffer data into a file required a lot of low-level system magic
What I learned
Never develop with systems currently in beta.
What's next for Freqkey
Remake it once Apple releases their bug fix.
