So, my aim is to build wireless interface between two microcontroller using nRF24L01. One microcontroller acts as a Tx, anden-USTelligent Community 13Thu, 27 Feb 2014 13:36:37 GMThttps://devzone.nordicsemi.com/thread/7492?ContentTypeID=1Thu, 27 Feb 2014 13:36:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:35e4ff83-6a05-4870-9547-1f995ded742bH&#229;kon Alseth<p>Hi,</p> <p>When the pin IRQ is asserted, then this indicates that an interrupt has occurred, depending on the bits masked in register CONFIG (MASK_* fields). If you set up a pin-change interrupt on IRQ pin, you should then get an indication. The source of the interrupt can be read from STATUS register.</p> <p>Best regards Håkon</p><div style="clear:both;"></div>
