CA (CCA Threshold)
This command applies to the XBee 3 802.15.4 RF Module.
Defines the Clear Channel Assessment (CCA) threshold. Prior to transmitting a packet, the device performs a CCA to detect energy on the channel. If the device detects energy above the CCA threshold, it will not transmit the packet.
The CA parameter is measured in units of -dBm.
You can set CA to 0 to disable CCA; this can improve latency but may cause interference with other 2.4 GHz devices when transmitting.
Parameter range
0 (disabled), 0x28 - 0x64 (-dBm)
Default
0x41
