Use the watch as a BLE key

[c-a-h]

It would be amazing to be able to use the watch as a BLE key - this way even if your phone dies, or you just decide to leave it at home, you can still unlock the car! I know this would have to use some undocumented APIs such as these: https://teslabtapi.lexnastin.com/docs/intro

I may try to hack at this if I get some time...

FWIW:

No [I never got this to work], it turned out that Garmin doesn't let you send more than 20 bytes at a time over BLE and they don't expose their NFC hardware with an API either. Much easier on WearOS, but I don't have one of those watches anymore. — /u/bean_khleb 66 days ago

Gadget Bridge had a recent pull request enabling communications with Garmin without use of the Garmin app. Perhaps a method could be gleaned from that work?
