What is it?

Make your Raspberry Pi3 B, Pi 3B+, Pi4 B, Pi 5 or Pi 0 to act as a single channel LoRaWAN gateway for LoraWAN Network Server such as TheThingsNetwork, Chirpstack or Gothardp.

Select freq 868, 915 or 923 Mhz, this freq can be changed in the config file.

Remark. This product includes a 9 cm.Antenna but does not include Raspberry Pi. Antenna might look difference from the showed picture.

Why did you make it?

Multi-Channel Gateway is too expensive for learning. If you have this single channel gateway, you can learn and test your programming for LoRaWAN node.

What makes it special?

Work with new Raspberry Pi 4B. You can have the LoRaWAN Gateway up and run in less than a day with this shield. Included 9 cm. antenna without Raspberry Pi and case. Need to have basic knowledge about raspberry pi.

You should bear in mind that this single channel gateway is not full function or compliance to LoRaWAN standard. It is a prove of concept product and enable you to start learning LoRaWAN and TTN. Only ABP authentication is supported.

Installation

Source Code Click here

Read Installation Section.

After installation, change pins configuration in global_conf.json to:

"pin_nss": 6,

"pin_dio0": 7,

"pin_rst": 0

Don't forgat to enable SPI on the Raspberry Pi (Use sudo raspi-config) before installation.

You also need to install wiringpi. (sudo apt-get install wiringpi)

If you use RPI0, edit single_chan_pkt_fwd.cpp and change eth0 to wlan0.

RPI3 B or PI3+ strncpy(ifr.ifr_name, "eth0", IFNAMSIZ-1); // can we rely on eth0? RPI0 strncpy(ifr.ifr_name, "wlan0", IFNAMSIZ-1); // can we rely on eth0?

After installation. Edit config file /home/pi/single_chan_pkt_fwd/global_conf.json

Frequency can be changed in this .json file.

If you want to start the program manually, run program as root. sudo ./single_chan_pkt_fwd Tip! In some cases such as a newer Raspbian on PI4, no need to have sudo just use ./single_chan_pkt_fwd

The installation script change RPI config to automatically start single_chan_pkt_fwd when RPI is rebooted. Manually run only for testing purpose.

Does this Single Channel gateway work with The Things Stack V3.

Yes, it works with TTS (TTN V.3) but it is not fully compatible. Only ABP and uplink. We encourage you using with Chirpstack or Gothardp Network Server. For TTS, change server address to "eu1.cloud.thethings.network".

Work with Raspberry Pi3, Pi4 and Pi5

Troubleshooting

Sometimes the gateway works, sometimes it does not. First, unselect Enforce duty cycle in Gateway general settings. Second, select reset frame counter in your ABP device settings
