This is part 28.2 of the LoRa/LoRaWAN tutorial.
In this video series different topics will be explained which will help you to understand LoRa/LoRaWAN.
It is recommended to watch each video sequentially as I may refer to certain LoRa/LoRaWAN topics explained earlier.
In this short tutorial I will show you how to enable debug logging in the Semtech LoRa gateway and Semtech UDP packet forwarder.
In this tutorial the following Semtech LoRa gateway and Semtech UDP packet forwarder are used:
Semtech LoRa Gateway (V5.0.1)
https://github.com/Lora-net/lora_gateway
/opt/ttn-gateway/lora_gateway *
Semtech UDP Packet Forwarder (V4.0.1)
https://github.com/Lora-net/packet_fo...
/opt/ttn-gateway/packet_forwarder *
*) For example in the RAK831 Pilot Gateway
Stop the ttn-gateway service:
sudo service ttn-gateway stop
The LoRa library contains a file (RAK831 Pilot Gateway):
/opt/ttn-gateway/lora_gateway/libloragw/library.cfg
where you can enable the debug logging for several modules.
To enable debug logging, change the value from 0 to 1.
DEBUG_AUX= 0
DEBUG_SPI= 0
DEBUG_REG= 0
DEBUG_HAL= 0
DEBUG_LBT= 1
DEBUG_GPS= 0
DEBUG_AUX
HAL auxiliary functions.
DEBUG_SPI
Functions to address the LoRa concentrator registers through an SPI interface.
DEBUG_REG
Functions used to handle FPGA register access for LoRa concentrator.
Functions used to handle LoRa concentrator radios.
Functions used to handle a single LoRa concentrator.
DEBUG_HAL
LoRa concentrator Hardware Abstraction Layer.
DEBUG_LBT
Functions used to handle the Listen Before Talk feature.
DEBUG_GPS
Functions to manage a Global Navigation Satellite System (GNSS) module, typically GPS, for accurate time-stamping of packets and synchronisation of gateways.
After the library.cfg file is modified enter the following commands in this order:
First, build the Semtech LoRa library:
cd /opt/ttn-gateway/lora_gatewaysudo
make clean all
Build the Semtech UDP Packet Forwarder:
cd /opt/ttn-gateway/packet_forwardersudo
make clean all
Start the ttn-gateway service:
sudo service ttn-gateway start
After you’re done with debugging don’t forget to set the values back to 0 in the library.cfg file otherwise the /var/syslog file will increase in size very fast.
