The button presses represent start/finish events for a race and are communicated to a tablet bluetooth app. I can communicate the button presses withen-USTelligent Community 13Thu, 29 Oct 2015 08:11:43 GMThttps://devzone.nordicsemi.com/thread/37007?ContentTypeID=1Thu, 29 Oct 2015 08:11:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d587ebba-3b2a-45a4-94c5-be360ca1444bAnders Strand<p>Hey.</p> <p>When in a connection, the tablet can turn the radio on at one exact time, receive a packet and then turn off the radio. When scanning continuously, it can never turn off the radio.</p> <p>Since the radio is a major power drain, the connection based solution will use the least amount of power.</p> <p>However, the best solution might change based on other variables, such as:</p> <ul> <li>How many beacons do you expect to communicate with at a given time?</li> <li>How low latency do you need between a button press and the tablet receiving it?</li> <li>Will the beacons be in range of the tablet at all times? If not, how many % of the time are they in range?</li> </ul><div style="clear:both;"></div>
