https://devzone.nordicsemi.com/f/nordic-q-a/6245/nrf24l01-reception-problemHello, I use two nRF24L01+ modules as a transmitter and a receiver, and Atmega8515 as my microprocessors. The transmitter seems to be working as I can see the modulation on a spectrum analyzer, however the receiver does not register anything. I am checkingen-USTelligent Community 13Mon, 30 Mar 2015 14:06:48 GMThttps://devzone.nordicsemi.com/thread/21860?ContentTypeID=1Mon, 30 Mar 2015 14:06:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b04d082b-480f-41ed-8ffe-04064063532dAsbj&#248;rn<p>So you do see that the IRQ changes on both the TX and the RX? When you say you read out the wrong payload, does that mean that the payload is completely wrong and do you do this after a RX_DR IRQ occurs?</p> <p>It seems like you only write one byte of addresses? Is this correct? You also have to match the TX address on the transmitter side with the RX_P0 address.</p> <pre><code>#define RX_ADDR_P0 0xDD 0xCD 0xFF 0xA2 0x0A //On the Receiver side #define TX_ADDR 0xDD 0xCD 0xFF 0xA2 0x0A //Transmitter TX address to match the RX receive address </code></pre><div style="clear:both;"></div>
