https://devzone.nordicsemi.com/f/nordic-q-a/46365/control-pa-lna-2401c-with-the-nrf52832-and-the-esbHi all, To keep compatible with previous devices, I need to use Enhanced ShockBurst on 52832. Now I need to add PA / LNA control to Enhanced ShockBurst, but I can&#39;t find any reference. I guess this can be achieved through PPI and GPIOE, but I donen-USTelligent Community 13Fri, 26 Apr 2019 08:45:52 GMThttps://devzone.nordicsemi.com/thread/183992?ContentTypeID=1Fri, 26 Apr 2019 08:45:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ad32051b-050c-42e0-a0ee-a5304b622e67Jared<p>Hi,</p> <p>We use the HW solution of PPI and GPIOTE to control LNA/PA with the Softdevice because the Softdevice source code isn&#39;t publicly available. However, the ESB code is available in the SDK, which means that you don&#39;t have to use the HW solution, but can rather alter the SW code for the ESB. The nrf_esb.h file shows that pin 27 is set once radio transmission is executed with ESB. You should be able to use this pin to control the PA/LNA. Just make sure that it satisfies your timing requirements.&nbsp;</p> <p>Best regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
