CC1352P: Does CC1352P support antenna diversity

There are no plans of supporting antenna diversity on the CC1352P at the moment.

On CC1310 we have an antenna diversity patch that you can use. You can also have AD on CC1352, but you need to implement the algorithm in SW yourself, using the the CS command.

To implement antenna diversity, you need to evaluate the received signal on the antenna.

How you want to do this this is up to you. The simplest way is to evaluate the first antenna, and if there is a signal with a certain signal strength present, you simply stay on that antenna. If not, you select the other antenna and check that one.

Another approach is to always check both antennas, and if both have a signal above a given threshold, you select the one with the strongest signal

If you only want to use RSSI to determine which antenna to use, you can either use the CMD_PROP_CS command for this, or you can simply enter RX mode and read the RSSI.

If you also want to check for preamble, you will need to use the CMD_PROP_CS.

This command is explained in the TRM and also here:

thank you, i will try it.
