https://devzone.nordicsemi.com/f/nordic-q-a/5799/nrf24l01-won-t-transmitI am using ATmega32s to drive the nRF24L01+ chips and a low dropout 3.3v regulator (TI’s LP2950) to power the nRF from the five volt buss. Both the transmitter and receiver use the same code. I use a digital I/O pin to select whether to transmit or receiveen-USTelligent Community 13Thu, 12 Mar 2015 13:37:38 GMThttps://devzone.nordicsemi.com/thread/20275?ContentTypeID=1Thu, 12 Mar 2015 13:37:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0eacde51-3701-4e35-ab80-f8f726bd0c30Asbj&#248;rn<p>A simple way of verifying that the sender is actually transmitting is by checking the VDD_PA pin on your module. This will go up to 1.8 V when it&#39;s transmitting. That way you would at least determine if it&#39;s an issue with the transmitter or the receiver. On the transmitter, you pull the CE pin high for how long? Are you using auto-ACK?</p><div style="clear:both;"></div>
