https://devzone.nordicsemi.com/f/nordic-q-a/860/nrf24le1-ack-protocol-with-pid-identityHave anybody a solution for my problem ? nRF24LE1 is first in low power state (PWRDWN is 3 or 4) and wakes to send a message. Mostly the message has the same PID identity i think because powerdown clears the memory. So the reiceiver sees the same PIDen-USTelligent Community 13Thu, 10 Apr 2014 14:01:12 GMThttps://devzone.nordicsemi.com/thread/4205?ContentTypeID=1Thu, 10 Apr 2014 14:01:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:94e77295-3b3a-44c9-8f98-cf74df16dc0dAsbj&#248;rn<p>Yes, for every time you power the chip down, the PID will be reset too. So you would have to add a counter or random number to the payload to make them different for each transmission. This is normally just an issue during initial testing though as you would have different payloads in normal operation of application.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/4203?ContentTypeID=1Sun, 10 Nov 2013 14:24:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0ad00ab6-7043-48c1-a940-8ec7de23baecBastiaan<p>.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/4204?ContentTypeID=1Sun, 10 Nov 2013 14:24:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:66f7e2f8-20ce-42f1-8d8d-c4376ab14cfcGuest<p>.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/4202?ContentTypeID=1Fri, 08 Nov 2013 14:51:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1c7b306d-9db0-4404-87f5-0220cc731de3Heikki Palom&#228;ki<p>I found only one solution: i must change the message content for example using random generator. So the receiver sees every time a new message.</p><div style="clear:both;"></div>
