- Introduction
This software configures the FPGA for "Liste-Before-Talk" feature and continuously reads the LBT channels timestamps which indicate when was the last instant when the channel was free.
- Dependencies
A SX1301AP2 Ref Design board with its FPGA programmed with LBT feature
- Usage
Before running the util_lbt_test application, the concentrator MUST be first started with the HAL, using for example util_pkt_logger or the packet forwarder with LBT feature disabled, as the util_lbt_test will configure it.
For a description of the command line options available: ./util_lbt_test -h
ex: ./util_lbt_test -f 867.1 -r -80 -s 5000
This will set 8 LBT channels, starting from 867.1 MHz, then each subsequent channel being set to the frequency of the previous channel +200 KHz (867.3, 867.5, ...).
The above test will run for ever, with a CHANNEL_SCAN_TIME of 5000µs and a target RSSI of -80dBm.
Please refer to the lora_gateway library readme.md to get more details on the LBT feature implementation and configuration.
