  • 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 :)




  • Ahh fair enough. I can see where you’re coming from.

    I find the added redundancy to be a beneficial addition in my scenario, particularly for emergency situations where cell service is out (due to overuse/congestion).

    These don’t need multiple points of redundancy to work but it does add peace of mind imo. Decentralization is a core principle of Meshtastic so that’s also another strong point that pushed me towards the protocol.

    But I can respect not everyone has the same requirements or interests :)




  • Very low cost of entry ($30-40), mesh capability for redundancy, and its on fairly accessible public bands although it occupies a specific part of it. Also it comes with end to end encryption.

    It’s just a far more cost effective solution compared to having a CB radio, where you’d need to be licensed to have certain features or to communicate on VHF/UHF etc. You also wouldn’t need to learn any sort of HAM based etiquette to operate these devices.

    Although if you need the extra capability, like voice comms, and want the flexibility that comes with HAM you can also incorporate these into that system.





  • You wouldn’t need internet access for these to work, although there is a public community WAN server you could join to operate under MQTT (which is their internet facing WAN function). They function off of LoRa RF on the 915mhz band in the U.S. (and other bands elsewhere) to do the bulk of the communication. BLE is also utilized for management.

    These do need more than 1 node to operate properly, but since it works off the concept of a public mesh (with options to privatize), you don’t need two of your own devices in a developed location.

    However, if no one is around or within line of sight… then you’ll have to work a little harder to get contacts/connections going.
