Key quotes
· 5 pulledThese radios didn't come with GPS, which in hindsight I regret because Meshtastic can share your location if a GPS is present.
The community warned that the cheap antennas bundled with these devices are nearly useless (yet another thing I learned in hindsight).
Out of the box, the devices had outdated firmware and wouldn't communicate with current Meshtastic app.
Meshtastic is an open-source project that lets you use inexpensive LoRa radios as a long-range, low-power mesh network.
The process was straightforward: plug in the device, open the web flasher, and follow the prompts.
