It\nuses [The Things Network Community Edition](https://www.thethingsindustries.com/docs/getting-started/ttn/)\n(LoRaWAN) for bi-directional data connectivity.\n\n## Features\n\n- Free to use with good coverage in nearly all major cities [around the world](https://www.thethingsnetwork.org/map).\n  * Note: as of December 2021, the software is configured to work in Europe.\n    This may be improved in the future.\n- Send text messages up to 100 characters in length.\n- Receive text messages up to 50 characters in length.\n- Display and transmit GPS location.\n- Display and transmit environment (temperature, humidity, pressure) readings.\n- Fox-hunt nearby 2.4GHz WiFi and Bluetooth LE transmitters.\n\n## Supported hardware\n\nAs of December 2021, the software exclusively targets the TTGO T-Beam board\nrevision v1.1. In addition, the software is configured to work with European\ncities by using the `EU868` frequency plan. These may change in the future.\n\n\"TTGO T-Beam\" is an IoT development board manufactured by Chinese company\n[\"LILYGO\"](https://twitter.com/lilygo9). The board features:\n\n- An ESP32 microcontroller with built-in 2.4GHz WiFi and Bluetooth LE\n  transceivers.\n- A LoRa transceiver.\n- A GPS receiver and its ceramic antenna.\n- A battery holder for 3.7V 18650 cell.\n- A 0.96 inch OLED.\n  * The display is often sold as an add-on.\n- A BME280 environment (temperature, humidity, and pressure) sensor.\n  * The software will continue to function even without this sensor.\n  * Be aware that some Chinese merchants deceive buyers by shipping them BMP280\n    sensors. The software does not support BMP280.\n\n\u003cimg src=\"https://github.com/HouzuoGuo/hzgl-lora-communicator/raw/master/media/system-monitor.png\" /\u003e\n\n## Get started\n\nFollow wiki article [Get started](https://github.com/HouzuoGuo/hzgl-lora-communicator/wiki/Get-started)\nto create a new device on The Things Network console, and write the firmware\nonto your TTGO T-Beam.\n\nThen check out wiki article [Usage](https://github.com/HouzuoGuo/hzgl-lora-communicator/wiki/Usage).\n\n## Copyright\n\nCopyright (C) 2021-2022 Google Inc.
