 I am using NRF51822 in receiver mode with enabled interrupt on ADDRESS event, and even if transmitter is switched off I still get a few messages every second. It also applies to END event. How should I solve this?

&lt;p&gt;It looks like to me that you have disabled CRC and use 1byte base address?&lt;/p&gt;
&lt;p&gt;When demodulating random noise on air, it statistically can hit any 2byte (prefix + base) address every 66ms, since 2byte is 65536 combinations @ 1Mbps.&lt;/p&gt;
&lt;p&gt;So I suggest to increase base length address and enable 2byte CRC to reduce risk of false address match and false received packet.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;br /&gt;Kenneth&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
