Feature Request: GPIO Beacon trigger

[DrCoolHands]

Hello,

I've been using Direwolf as a vehicle tracker for some time now with great success.
While Smart-beaconing is great for general position use, I suggest adding an option to trigger the transmission of a beacon based on a GPIO pin. Not limited to just the TBEACON type.

Examples: Mains power loss, external sensor, manual button-press for event marking.

Thoughts?

Thank you for your continued efforts!

I was thinking about this too! One way I was thinking of solving it instead of adding to Dire Wolf would be to write a simple KISS client that takes care of listening for GPIO pins and also talking to the gpsd (or signaling a fixed position) and then constructs the APRS packet.

For instance there are a lot of Python libraries for doing GPIO, and at least one KISS client library.

It's in my "when I have time" bucket behind building my PTT circuit 😄
