Toot

Written by Alper on 2025-02-01 at 22:09

I am on the verge of buying an e-ink screen for an #esp32 board and start a vendetta against #garmin by making a foretrex of my own that will be used as an #aprs/lora and whatnot terminal besides navigation.

While #foretrex is still the least #enshittified device Garmin makes, it having bluetooth and can do crap with it drives me crazy. My radio, my gps, my pc have BT and non can talk to each other.

What do you think?

@alper so your issue is the Foretrex not talking to your radio and your PC?

@me Actually radio is secondary. I want to send this device a location wirelessly from my other devices. Just think a scenerio you use your mobile device to browse the map. And send a location from there directly to foretrex over bluetooth. Which it cannot receive even with garmins crappy software. Why the hell you put bt in this device? Just phone notification?

I think there are some military applications of it but i don't care.

@alper ah

yes, the Garmin app ecosystem is a little bit limited (at least from the perspective of a Garmin Venu Sq owner), it still seems to be centered around the Garmin Express desktop app

@me Garmin used to make the best hardware...

And most likely they knew they would suck at software so they never touched it back than!

Foretrex series still keep, most likely due to US army, have many old simple and free interfaces. I think it is the last device left in Garmin lineup that lets you can connect it via usb and it will behave as drive and let you download or upload any standart gpx file.

I want the same thing, just over bluetooth =) serial nmea is best of course...

@alper my Venu Sq appears as a drive too (albeit with .fit files)

oddly enough, it does pop up as a garmin_gps serial device, and it acts as a GPS unit for gpsbabel

@me That is great. Perhaps at the end of its life it may be a gps receiver for many projects 😂

@alper I have never understood why Garmin, TomTom and the likes do not have an interface to receive positions for objects and display them on the map. It would be extremely useful for group riding, mountaineering etc without tying you to a specific position sharing technology - simply provide an API and let users choose APRS, meshtastic, Owntracks over cellular, TETRA or whatever they want.

@mbpaz Early 2000's Garmin devices had plain serial interfaces that accepted NMEA strings. There are some examples of them used for #aprs tracking with th-d72 with cable.

I still sport a #60csx and it can be used in that fashion if I make a custom bt module for it with an off the shelf hc-05 module but foretrex is all I need and practical device.
