https://devzone.nordicsemi.com/f/nordic-q-a/6292/differences-between-nrf24l01p-and-nrf24l01p-pa-lnaHi! Is there any configuration differences between those 2 modules?? I understand from the data sheets that the pinout is just the same. I&#180;m testing a PA+LNA on the same hardware and firmware that works with the nRF24L01p, and with the PA+LNA nothingen-USTelligent Community 13Tue, 31 Mar 2015 13:45:02 GMThttps://devzone.nordicsemi.com/thread/21972?ContentTypeID=1Tue, 31 Mar 2015 13:45:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3a608fe8-7b01-4e45-bb69-708690d2df00Asbj&#248;rn<p>I don&#39;t know what kind of modules you have or what they can do. There are a lot of different module implementations out there and we are not familiar with all of them. I would have to ask you to turn towards the module manufacturer in order to find out what kind of functionality is available on the modules you have.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/21971?ContentTypeID=1Mon, 30 Mar 2015 19:15:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:27a28dbe-9488-40a4-a6e3-c7456689cb33pendor<p>Hi Asbjørn ! The problem is solved! As usual, it was several misconnections. Once corrected, the PA+LNA behaved correctly. But, by the way, do these modules need any extra config to increase power or something? Or they are just plug-and-forget replacements for the nRf24l01plus with only an external antenna? Thanx again!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/21973?ContentTypeID=1Mon, 30 Mar 2015 14:44:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7acb3edc-2bf2-469b-88cb-b247b57d8c08Asbj&#248;rn<p>What kind of modules are you using? Could it be that there&#39;s a pin to enable the TX chain on the PA on the module in order for it to work as a transmitter? If you use the PA module as a receiver, does it send ACKs back to the PTX?</p><div style="clear:both;"></div>
