How do I use the ST60-2230C or the SU60-2230C with only one antenna (SISO mode)?

While loading the lrdmwl.ko kernel object you will need to add the option SISO_mode. The value would depend on which antenna port is to be used.

        SISO_mode:
        0: WiFi --> ANT Wi-Fi & ANT Wi-Fi+BT ports
        1: WiFi--> ANT Wi-Fi  port
        2: WiFi --> ANT Wi-Fi+BT port

You will need to terminate the unused antenna port with a 50 ohm terminator, otherwise, it could damage the PA of the unattached antenna port, due to energy rebounding during driver/firmware Initialization and you run the risk of not being able to leverage our certifications.
