How to enable the external U.FL antenna on FRDM-RW612 EVK Hi NXP Team, I'm using the FRDM-RW612 EVK with the wifi_cli example from the SDK. The Wi-Fi firmware loaded is rw61x_sb_wifi_a2.bin. I have connected a Molex 1461539050 external antenna to the UFL connector (J11) on the EVK. However, I do not observe any improvement in the RSSI compared to the onboard PCB antenna. In some cases, the RSSI is even slightly lower. From the FRDM-RW612 schematics and user guide, I understand that the RF switch (U16 - RTC7608U) selects between the onboard PCB antenna and the external UFL connector and that RF_CNTL_3 is the control signal for this switch: RF_CNTL_3 = 0 -> PCB antenna (default) RF_CNTL_3 = 1 -> External UFL antenna How to control RF_CNTL_3 ? Is RF_CNTL_3 driven automatically by the Wi-Fi firmware ? If yes what is its default value ? How to modify that value ? Is any hardware or firmware configuration required to enable the external antenna on the EVK? Any guidance or example code would be greatly helpful. Thank you.

Regards, Daniel. Re: How to enable the external U.FL antenna on FRDM-RW612 EVK Hi @DanielRuvalcaba I also would like to switch antenna to UFL connector (J11) on FRDM-RW612. Could you please share information how to do it? Are we switching antenna through Front-end module (FEM) settings? Regards Marcin Re: How to enable the external U.FL antenna on FRDM-RW612 EVK Hi,
