3.2.56 mac set_lbt <Switch>
<Switch>: A string representing whether S76G enables its LBT feature, it could be used to listen the
TX channel before executing TX uplink, it can be on or off.
Response: Ok, if <Switch> string is valid.
Invalid, if <Switch> string is not valid.
Purpose: By TELEC request, it needs to detect a channel is using or not before using this channel, so
if LBT is on, S76G/S78G can listen before talk (LBT) the channel symbol signal strength before any TX
uplink like joining or normal uplinks. If the channel is occupying, S76G/S78G would skip to another
channel and LBT again until it finds an available channel.
Example:
mac set_lbt on
>> Ok
sip set_log debug
>> Ok
mac tx cnf 3 11223344
...
--> CAD found at 868100000 rssi is -30 dBm
(It means it found the symbol RSSI is too strong at 868.1MHz, it must be small than -80dBm)
(Change to another channel and LBT again)
--> CAD found at 868300000 rssi is -40 dBm
(It means it found the symbol RSSI is still too strong at 868.1MHz)
