But after nrf8001 first STAND-BY mode, I don&#39;t know how to wake up the nrf8001?en-USTelligent Community 13Tue, 24 Apr 2018 15:06:09 GMThttps://devzone.nordicsemi.com/thread/129619?ContentTypeID=1Tue, 24 Apr 2018 15:06:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ea6722d6-3090-41df-b0b2-9209b83d2d98David Edwin<p>The nRF8001 should be put to sleep using the sleep command and then woken up using the Wakeup command.</p> <p>You can then send the ACI Broadcast command to broadcast the packets.</p> <p>If you do not want to use the sleep command then the nRF8001 will be in Standby mode all the time and is ready to accept commands.</p> <p>The sleep mode consumes less power as compared to standby, see the Section 12.4 for Current Consumption parameters for I_idle and I_sleep</p><div style="clear:both;"></div>
