In the head of the file there are some general settings concerning the private/public LoRa
network setup. The setting for the internal clock must not be changed. Next 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 settings called “type”
must be kept unchanged (SX1257).
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.
For further details please check the documentation.
After checking the configuration the tool can be started via:
cd lora_gateway/util_pkt_logger
./util_ptk_logger
