https://devzone.nordicsemi.com/f/nordic-q-a/95818/activate-fem-sky66112-in-bt840x-using-wirepasGood morning to everyone. I&#39;m having some trouble trying to activate the Front End Module (FEM) SKY66112 that it is integrated with the nrf52840 in a ev-BT840X fanstel board. This module increments the TX signal power in order to get some distance betweenen-USTelligent Community 13Thu, 09 Feb 2023 08:38:21 GMThttps://devzone.nordicsemi.com/thread/409066?ContentTypeID=1Thu, 09 Feb 2023 08:38:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6d4ea2bf-908a-4e28-8489-55d4e37ff49bketiljo<p>You need to ask Wirepas, it&#39;s their software stack.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/408990?ContentTypeID=1Wed, 08 Feb 2023 19:44:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:adfd9d66-15ef-49d8-89a4-6b540c61176fdarkenergy42<p>Any info about this?

Only FHSS can use more than 10 dBm.</p> <p>TX/RX switching of the FEM is tightly integrated into the lower levels of the protocol so you need to ask Wirepas about this.&nbsp;</p><div style="clear:both;"></div>
