In the head of the file there is one config block for each radio of the concentrator. Each radio
can be turned on / off and operates on a certain base frequency. (See block “
radio_0
” and
“
radio_1
”). The following blocks define the parameters used by the virtual multi SF channels.
Each logical channel configuration consists of the radio to be used and the RF frequency. The
RF frequency is defined as difference to the base frequency defined in the corresponding radio
config block.
After checking the configuration the tool can be started via:
cd lora_gateway/util_pkt_logger
./util_ptk_logger
After starting the packet logger, please send out some data with another radio module. In this
document it is assumed that the user is familiar with the WiMOD iM88xA radio module or the
iU88xA USB-Stick and the Windows Software called “WiMOD LR Studio”
1
or “WiMOD ExpLoRa
Studio” or “WiMOD LoRaWAN EndNode Studio”.
In order to send some data start the Windows software and navigate to “Configuration” and
make sure the TX setup matches one of the configurations in the
global_conf.json
file
within the
util_pkt_logger
folder on the linux host. After setting up the radio TX
configuration, navigate to “Radio Services” / “Data Link Service” and start sending some test
messages.
In order to inspect the RX data from the iC880A device stop the
util_pkt_logger
by
pressing
Ctrl+C
and open the CSV file in the current folder.
The following screen shot shows the TX and RX data:

The WiMOD LR Studio is intended to be used with a WiMOD Module running the WiMOD LR-Base firmware. The
other PC software is intended to be used in conjunction with a WiMOD Module running the WiMOD LoRaWAN
firmware.
