At speeds up to, say, 60mph (97km/h; 27m/s) ?en-USTelligent Community 13Wed, 28 Oct 2015 10:11:33 GMThttps://devzone.nordicsemi.com/thread/36791?ContentTypeID=1Wed, 28 Oct 2015 10:11:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:804c3ea4-4452-4704-8378-1a375676de23Anders Strand<p>Hey!</p> <p>This is possible, but your success rate is a pure statistical calculation. I will try to give you some input to base your decision on.</p> <p>At 27 m/s velocity, let us assume that you are within BLE range for 1 second. If the beacon broadcasts at 1000 ms intervals, you might pick up this broadcast. This is assuming that your scanner is on 100% of the time. The scanner must switch between 3 broadcast channels, so it will be down in short pauses ever so often. This means that broadcasting once a second will probably not work. Broadcasting twice a second doubles your chances, but there is still a chance to not pick up the broadcast.</p> <p>So this purely comes down to broadcast interval, and scan interval. These two must overlap at some point during the one second you are in range. If we assume 100% scan uptime, i would guesstimate that 3 or 4 broadcasts/second will work. I think the only way to know this is to test it. You might have interference from the car or other devices which impacts your results.</p> <p>If you are buying pre-made beacons, i would assume that this will not work. This is because a normal beacon broadcast interval is about 1000 ms or more.</p><div style="clear:both;"></div>
