https://devzone.nordicsemi.com/f/nordic-q-a/127695/dynamic-enabling-disabling-sky66112Hello, I&#39;m using Fanstel&#39;s BT840X that includes a SKY66112 front end. It works great with the FEM module in NRF Connect SDK. My problem is that my device has the option to run on batteries or wired to power. I would like to be able to disable the SKY66112en-USTelligent Community 13Tue, 07 Apr 2026 09:52:42 GMThttps://devzone.nordicsemi.com/thread/564492?ContentTypeID=1Tue, 07 Apr 2026 09:52:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9332a1e1-2503-49ec-b2fc-55c72351705cVidar Berg<p>Hello,</p> <p>Based on table 6 in the datasheet (<a href="https://no.mouser.com/datasheet/3/564/1/SKY66112_11_203225P.pdf">https://no.mouser.com/datasheet/3/564/1/SKY66112_11_203225P.pdf</a>), the FEM should already be in all off mode between RADIO transactions. If you are using the radio while battery powered you still need to enable the FEM on RX and TX, but you can assert the CPS signal to use the bypass mode to reduce the peak currents.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
