So the receiver can measure if the power in the receive channel is above or below -64 dBm and hence you have either on or off. So the measurement type will be different as the RSSI is only available on ANT devices based on the nRF51422. So on the nRF24AP2 there&#39;s no real RSSI, but if I am to guess since the ANT protocol was developed by Dynastream, I would guess that they also play around with the output power on the sender to see how that affects the 1 bit RSSI on the AP2. This is just my guess though as I&#39;m not sure on what the threshold part of the RSSI extended measurement means.</p> <p>Proximity search: <a href="http://www.thisisant.com/resources/an12-proximity-search">www.thisisant.com/.../an12-proximity-search</a></p> <p>RSSI extended info: <a href="http://www.thisisant.com/resources/an16-rssi-extended-information">www.thisisant.com/.../an16-rssi-extended-information</a></p><div style="clear:both;"></div>
