+Lora Gateway LBT basic test application
+=======================================
+
+1. 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.
+
+2. Dependencies
+----------------
+
+A SX1301AP2 Ref Design board with its FPGA programmed with LBT feature
+
+3. 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.
+
