sudo vim ./libLoRagw/inc/LoRagw_i2c.h
Change #define I2C_DEVICE "/dev/i2c-1" to #define I2C_DEVICE "/dev/i2c-3".
4. Compile the code:
sudo make
5. Modify the configuration code:
sudo vim ./tools/reset_lgw.sh
Update the pin configurations:
SX1302_RESET_PIN=580 # SX1302 reset
SX1302_POWER_EN_PIN=578 # SX1302 power enable
SX1261_RESET_PIN=579 # SX1261 reset (LBT / Spectral Scan)
6. Copy the reset_lgw.sh script
cp ~/sx1302_hal/tools/reset_lgw.sh ~/sx1302_hal/packet_forwarder/
7. replace the default SPI port of the LoraWAN® Module in the global_conf.json.sx1250.US915 config file:
sed -i 's/spidev0.0/spidev0.1/g' global_conf.json.sx1250.US915
8. Start LoraWAN® Module
cd ~/sx1302_hal/packet_forwarder
sudo ./lora_pkt_fwd -c global_conf.json.sx1250.US915
These steps will configure LoRa® SPI and run the packet forwarder with the specified configuration file.
3.7.2 LoRa
®
USB
For LoRa
®
USB, the previous commands remain the same as for LoRa
®
SPI. However, the final command needs to be
changed to:
#pull up the SX1302_RST pin first
echo 1 > /sys/class/gpio/gpio580/value
./LoRa_pkt_fwd -c global_conf.json.sx1250.EU868.USB
This command specifies the configuration file to be used for LoRa
®
USB.
3.8 4G Cellular over Mini-PCIe
To interact with a 4G module using AT commands via minicom, follow these steps:
1. Open minicom with the appropriate serial port and baud rate:
sudo minicom -D /dev/ttyUSB2 -b 115200
This command opens minicom with the specified serial port (/dev/ttyUSB2) at a baud rate of 115200.
2. Once minicom is open, you can start sending AT commands to the 4G module. For example:
AT
This command checks if the module is responsive. You should receive an "OK" response if the module is working properly.
