Enable the BLE (Bluetooth Low Energy) LBT (Listen Before Talk) function. Before transmitting a packet,
|

monitor the in-band CCA (Clear Channel Assessment). If the airborne carrier energy is too high, abandon
|
||||
the packet transmission. Enabling this feature may potentially decrease BLE performance. In certain
|

countries and regions, when the maximum transmission power exceeds a certain limit, support for LBT
|

interference avoidance mechanisms is required. If the maximum transmission power does not reach the limit,

it may not be necessary to enable this function.
