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.
Please refer to the relevant certification regulations for details.

If a carrier signal above the threshold is detected in the air, refrain from packet transmission.
