LoRaWAN

LoRaWAN is an RF standard for IoT devices to connect to the internet.

TTN Mapping

ttnmapper.org allows to create a coverage map of the TTN LoRaWAN network. You can take a LoRaWAN node, either with integrated GPS, or pair it with a smartphone, and gather coverage data.

A node with GPS is nice, because it's more independent. An ideal candidate is the TTGO T-Beam dev board, which combines an ESP32, GPS module and a LoRa module, as well as a battery and potentially an OLED display as well.

• Basic firmware w/o OLED support
• Firmware by Hotti with OLED support
• Port of Hotti's FW to platform.io

Note that there are different versions of the T-Beam board, requiring different Pin settings.
