In grobal_conf.json file, I get an error when I enable LBT as follows
“lbt_cfg”: {
“enable”: true,
Upon startup, an error occurs at the end as shown below.
INFO: packets received with a valid CRC will be forwarded
INFO: packets received with a CRC error will NOT be forwarded
INFO: packets received with no CRC will NOT be forwarded

The version of the gateway is as follows：
$ gateway-version
Raspberry Pi Zero W Rev 1.1, OS “10 (buster)”, 4.19.75+.
RAKWireless gateway RAK7246 version 4.2.0R install from firmware.
Gateway ID: b827ebfffe・・・
If I set lbt_cnf to false, it works.
How can RAK7246D0 use LBT?
