The Latest Firmware
Meshtastic Mesh Device Nano Edition G1 had been supported by the official meshtastic repository on Github from firmware version 1.2.61. Thus, the latest firmware could be downloaded from the meshtastic project’s releases page:
Firmware file: firmware-nano-g1-1.x.x.bin
The Fimware may also be updated by using Meshtastic GUI Installer. Meshtastic GUI Installer is a cross platform, easy to use GUI for installing Meshtastic firmware.

Real World Testing
The coverage of this credit card size Lora device was tested in the urban area which full of more than 150m skyscraper towers. In the experiment (TX:20dBm, Freq:915Mhz, Long/Slow), 2000m communication distance had been tested. At the distance of 1800 meters, the device was completely normal. At the distance of 2000 meters, the function of sending messages was still normal, but the device status and location information could not be updated normally.
