https://devzone.nordicsemi.com/f/nordic-q-a/3778/current-conusption-if-ant-rx-didn-t-receive-dataHi Now, we are planning to implement an ANT+ RX (slave). I checked nRF51422 product spec. Radio current consumption is 12~13mA if receiving data between 250kbps and 2Mbps. Do you know the current consumption if receiving no data from ANT+ TX (masteren-USTelligent Community 13Fri, 12 Sep 2014 08:30:53 GMThttps://devzone.nordicsemi.com/thread/13677?ContentTypeID=1Fri, 12 Sep 2014 08:30:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f0015624-f523-4fd1-91e8-dac146b4c340testy<p>When your ANT+ channel is in <strong>SEARCHING</strong> state, the current consumption with sd_app_evt_wait() active will be up to <strong>2.5mA avg</strong> during ongoing Search Timeout+Low Priority Search Timeout. Then follows <strong>ASSIGNED</strong> status with EVENT_CHANNEL_CLOSED generated (ANT+ slave channel autoclosed - must be reopened manually if desired, although ANT+ master&#39;s transmitting is renewed after slave&#39;s timeouts expiration) and current will drop to nRF51 <strong>System-ON base current</strong> (if no other peripheral is enabled, e.g. RTC1 or another/master channel running).</p> <p>You should do the ampermeter measurement Yourself to verify code anyway.</p><div style="clear:both;"></div>
