When deploying a LoRaWAN network you want to know your gateway coverage and measure the radio performance in different places. When deploying Helium network you particularly want to know how many Hotspot around can be touched for a given position. Then you want to enrich the network mappers to know and share the real network coverage.
There are some existing tools for such application but the cost is about $200. The idea of this project is to propose a simple tool you can build on your own with low cost hardware to fulfil this purpose.
The solution is based on low cost products, easy to find for about $50:
- Wio Terminal
- RFM95
- Quectel L80 / L86 GNSS
The solution also supports ready for use hardware:

If you are using a Seeed bundle, it is already setup, you don't need to do anything more

- Support firmware upgrade w/o credential loss (LoRa-E5 only)
- Reduce uplink messages when device is not moving / out of coverage
- Discovery Mode - allow to see hotspot communications on a map (external website)
- Works with TTN and Helium
- manage US915 SF10 differently (donwlink size too large by default)
- sdcard data storage
- low power management for longer autonomy

The US915 SF10 is restricting the size of uplink and downlink. Uplink is adapted but donwlink frame is currently too large. The Uplink are correctly sent but the "LOST" status is indicated when the Downlink is not received. So "LOST" is always displayed. Do not use SF10 in US915 if you want to get the uplink information. This will be fixed in a later version. Mapper and tracker features are working correclty even this.
The Seeed bundle comes with ready to use credentials. You don't need to setup your device. If you want to move your device out of the factory credential and move the device to your own console account or TTN, you can follow the documentation here. Once done, you won't be able to rollback to factory settings.
Some of the LoRa-E5 chassis have an incorrect default UART speed at 115200. To reset it to the normal value, flash the firmware Gps_Reset_To_9600bps. Then you wait for about 1 minute and then reflash the latest version. This should fix it.
