IIRC all devices would update according to firmware, so I believe it’s 30 minute updates. You can change that to much faster timeframes before chirps are sent out, but that will begin to drain battery life. (Can also manually request position and request updates in app)
If you’re concerned about battery life stay away from ESP32 devices and look strictly at nRF52840 devices, from RAKwireless and soon LILYGO/Heltec as well.
I personally haven’t used them for this use case, mine are primarily being setup as solar repeaters to build a local emergency mesh network. But I’ve seen some very neat use cases for Meshtastic so I’m curious if this could work!
Good luck :)
I've found a heltec with an nrf52840 with gps and all on aliexpress ;) Im gonna watch some more videos and decide if this is the route I want to go, thanks!
Did you go with this? It's a really cool use-case.
Sorry! I didnt see your comment until now. I'll copy paste what I've written to the other user:
I've bought two nodes and attached some gps i had lying around, works pretty good for a proof of concept. It's kinda slow to update the positions tho, but the biggest drawback is that yoy need to have the app open to see anything because the oled screens are very very unreadable under the direct sun.
How’d it work out for you?

Ah bummer. I have the same problem and rapid updates would be great. Thanks for the update!
