German Amateur Radio Station


The firmware turns the LoRa module into a working device.

I have chosen the firmware from DL9SAU. This firmware is easy to install (flash) and the configuration is done via a WEB interface.

The flashing of the modules is relatively simple.

Required is the ESPHomeFlasher Windows 10 + 11

For other operating systems you can find the ESPHomeFlasher here

ESPHomeFlasher Releases

and the corresponding firmware file

Here you can find the latest tracker firmware ( for T-Beam board)

Here you can find the latest gateway firmware (For LORA32-Board)


 Under normal circumstances you take a LoRa32 module for the iGate, because here the position is fixed and no GPS is needed.
But for the tracker GPS is needed, so here the T-Beam module, which has an additional GPS chip.
But you can also use a T-Beam as iGate, the firmware can do both, tracker and iGate.
It is only important to choose the right firmware for the board!

Attention: The above downloadable files are based on the work of Thomas, DL9SAU and were modified by Karl-Heinz, DD7EN.

The output of the GPS data with Putty or in the console from ESPHomeFlasher is experimental and can be reverted if necessary.

Flashing is very simple. Connect the module via USB cable to the computer.

After calling the ESPHomeflasher.

Important, there must be an internet connection!

After programming the HomeFlasher shows the received GPS data in the console window. After the first programming it takes up to 45 min. until the first GPS fix is received so please be patient ;o)

After flashing, a wifi network with the SSID: N0CALL AP and the password: xxxxxxxxxx
will be made available. Under the IP no.: you will find the WEB configuration.

Here changes to the callsign, symbol etc. are to be carried out.

Mouseover help texts guide you through the configuration.
