For nRF54L15, these must be added in hardware and configured in software by you. The DK board itself normally only has 1 antenna on it.&nbsp;</p> <p>Best Regards,</p> <p>Samruddhi</p><div style="clear:both;"></div>RE: Hello, I previously learned that the nRF54L15-DK only supports a single antenna for Bluetooth 6.0 channel ranging and lacks a multi-antenna design approach or official guidance for implementing multi-antenna configurations.

According to our documentation, the development boards don&#39;t provide multiple antennas for Bluetooth Channel Sounding. They only suggest how to configure multiple-antenna support for channel sounding. The nRF54L15 DK has a single antenna path and connecting more antennas would have to be done externally.&nbsp;</p> <p>Best Regards,</p> <p>Samruddhi</p><div style="clear:both;"></div>RE: Hello, I previously learned that the nRF54L15-DK only supports a single antenna for Bluetooth 6.0 channel ranging and lacks a multi-antenna design approach or official guidance for implementing multi-antenna configurations.

I have consulted the documentation on multiple antennas, which discusses configuration methods for multiple antennas. It states that currently, none of the Nordic development boards include hardware support for multiple antennas; the documentation only discusses configuration approaches. Have I understood correctly?</p><div style="clear:both;"></div>RE: Hello, I previously learned that the nRF54L15-DK only supports a single antenna for Bluetooth 6.0 channel ranging and lacks a multi-antenna design approach or official guidance for implementing multi-antenna configurations.

SoftDevice controller and libraries support multi-antenna channel sounding (up to 4 antenna paths configured with Kconfig options). However,&nbsp; our docs don&#39;t mention any DKs with a already made multi-antenna channel sounding RF design. nRF54L series radio does support channel sounding but the nRF54L15 contains only one PCB antenna. If you want to use multi-antenna channel sounding, you can choose a board supporting channel sounding. Then, add an external RF switch or antenna network. You can use cs_antenna_switch_func() and devicetree to configure it. I would recommend you to take a look at our <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/softdevice_controller/doc/channel_sounding.html#multiple_antennas_support">Multiple antennas documentation.</a></p> <p>Best Regards,</p> <p>Samruddhi</p><div style="clear:both;"></div>
