Support for US902-928 band 
Tested the setup with the below:
* TTGO T-Beam 868/915MHz (T22_v1.0, 20190612) - tracker (LY1XD-5)
* LILYGO TTGO 868/915MHz (T3_V1.6.1, 20210104) - iGate (LY1XD-4)

The band specifics are more in favour of direct line of sight, as most obstacles are impenetrable by the 915 MHz band (compared to 433 MHz).But maybe it will open up for users who don't have the EU433 available in their geographies.

LoRa APRS Tracker

The LoRa APRS Tracker will work with very cheep hardware which you can buy from amazon, ebay or aliexpress. Try it out and be part of the APRS network.

TTGO T-Beam

Supported boards

You can use one of the Lora32 boards:

  • TTGO T-Beam V0.7 (433MHz SX1278)
  • TTGO T-Beam V1 (433MHz SX1278)
  • TTGO T-Beam V1 (868/915MHz, SX1276)

These boards cost around 30 Euros, they are very cheap but perfect for an LoRa tracker/iGate.

It has been successfully tested within the US902-928 range with compatible 868/915 MHz TTGO devices. See the configuration section below.

Compiling and configuration

There is a german quick start page! Take a look ;)

There is a french quick start page! Take a look ;)

How to compile

The best success is to use PlatformIO (and it is the only platform where I can support you).

  • Go to PlatformIO download and install the IDE.
  • If installed open the IDE, go to the left side and klick on 'extensions' then search for 'PatformIO' and install.
  • When installed click 'the ant head' on the left and choose import the project on the right.
  • Just open the folder and you can compile the Firmware.

Configuration

  • You can find all nessesary settings to change for your configuration in data/tracker.json.
  • The button_tx setting enables manual triggering of the beacon using the middle button on the T-Beam.
  • To upload it to your board you have to do this via Upload File System image in PlatformIO!
  • To find the 'Upload File System image' click the PlatformIO symbol (the little alien) on the left side, choos your configuration, click on 'Platform' and search for 'Upload File System image'.

The US902-928 band

To get started with a T-Beam device working on the US902-928 band, you need to:

  • Tune the tracker frequency to the desired value from that band: 
    "lora":
{
  	"frequency_rx": 913880000,
  	"frequency_tx": 913880000,
  	...
}
  • Use the same values to configure the LoRa iGate on the file data/is-cfg.json.

The above example uses LoRa channel #6 (913.88MHz), but use it at your own risk and make sure to respect local regulations!
