Is there any Application Note like AN092 from TI on the current consumption of CC2541, but for the nrf51822? Did you know witch are the timing of an advertisement event in term of: MCU Wake up time Pre processing time RX time RX to TX time TX time post processing time pre sleep time</p> <p>Please give me some hint, I need to calculate exactly the current comsumpion of a nrf51822-BEACON without leds with an advertising interval of 1s, when advertising time is 10s.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14114?ContentTypeID=1Sat, 27 Sep 2014 16:31:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3d050be3-773e-4b3c-992d-07d6bc7bd47cOzgun<p>thank you Asbjørn</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14113?ContentTypeID=1Fri, 26 Sep 2014 13:49:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e71cd6ef-db6e-4e30-a5ea-c56d4ad85905Asbj&#248;rn<p>It depends on the interval between each advertisement and how much of the time you actually do advertisements. So lets say that you for a 100% of your day you will be advertising:</p> <ul> <li>1 time every second: Average power consumption: ~30 uA</li> <li>10 times every second: Average power consumption: ~200 uA</li> </ul><div style="clear:both;"></div>
