Lorawan gateway GW-01. Developers guide. Armbian.
You can build Armbian image for GW-01 from source. This gives you way to customize lorawan gateway.
To do that:
Clone Armbian OS project
$ cd build
There is image to write on microSD card.
Flashing image in microSD card
Remote access via SSH.
Look for orangepizero device on your DHCP server:
and connect to it via SSH:
User/pass to login: root/1234. Change password and add new user on first login. After that we are ready to configure spi interface and install all necessary libraries to get working lorawan gateway.
Enabling SPI on armbian on first booting
Check that spidev not exist in list of devices in filesystem
Add parameters to configuration file to enable SPI interface:
Change overlays param to:
overlays=usbhost2 usbhost3 spi-spidev spi-add-cs1
Add following at the end of file:
param_spidev_spi_bus=1
param_spidev_spi_cs=1
Exit and save file. Configure dts tree:
$ cd ~
$ dtc -I dtb -O dts -o sun8i-h3-spi-spidev.dts ./sun8i-h3-spi-spidev.dtbo
$ nano sun8i-h3-spi-spidev.dts
reg = <0x1>;
Exit and save file.
Then compile new dtbo file and replace old one with that:
$ dtc -I dts -O dtb -o sun8i-h3-spi-spidev.dtbo ./sun8i-h3-spi-spidev.dts
$ sudo rm /boot/dtb/overlay/sun8i-h3-spi-spidev.dtbo
$ sudo cp sun8i-h3-spi-spidev.dtbo /boot/dtb/overlay/
SX1301 reset script.
$ touch iC880-SPI_reset.sh
$ nano iC880-SPI_reset.sh
Installing lora_gateway
Download and modify the library
$ git clone https://github.com/Lora-net/lora_gateway.git
$ cd lora_gateway
$ nano libloragw/src/loragw_spi.native.c
Installing packet_forwarder
$ git clone https://github.com/Lora-net/packet_forwarder.git
$ cd packet_forwarder/
$ ./compile.sh
$ cp global_conf.json.PCB_E286.EU868.basic ../global_conf.json
$ nano global_conf.json
«gateway_conf»: {
«server_address»: «router.eu.thethings.network»,
«server_port_up»: 1700,
«server_port_down»: 1700,
}
$ sudo ./iC880-SPI_reset.sh
$ sudo chmod 777 /dev/spidev1.1
$ cd packet_forwarder/lora_pkt_fwd
$ ./lora_pkt_fwd
