[Xastir] Garmin Tempe

[Jason KG4WSV]

When ANT (not +) came out a few years ago I looked to see if it could be a Bluetooth-like connection to a mapping GPS. No joy then.  Now I see there’s the + version of the protocol, it’s still proprietary but “open access” instead of completely closed, and there are USB dongles available, so maybe it’s worth another look. 

I did some cursory googling and the only open source stuff I saw was python (ugh). 

RTL-SDR won’t work since ANT+ is 2.4GHz and the RTL tops out at 1.7GHz. 

I’d be surprised if the device simply transmitted every so often, since that’s not very power efficient. That would be the only way to make use of a receive-only station. you’ll probably need an ANT+ transceiver to talk to it. 

Still, worth looking into. I’d drop US$30 on a USB transceiver if it let Xastir plot waypoints on a Garmin mapping gps.
