https://devzone.nordicsemi.com/f/nordic-q-a/5924/beacon-project-guidanceGot the NRF6700 starter kit and a handful of nRF51822-beacons. Downloaded the DV environment and have read through the nRF51822 DK Users Guide (ver 1.4) and a handful of the the other documents. I have looked through the S110 and S120 examples.

Use the S120 in one as observer and then use the S110 in the beacon kits. Documentation on the API are available here: <a href="http://developer.nordicsemi.com/nRF51_SDK/doc/">developer.nordicsemi.com/.../</a></p> <p>Have a look at the S120 and the S110 examples. You can also use a phone or table to make sure that the beacons are working. Search for &quot;nrf&quot; in play store or apple store.</p> <p>The beacon kits can be used as S120 observers, but they have to be re-programmed through the programming interface on the beacon kit. By default the beacons only support S110 and where made before it was possible to upgrade the softdevice across BLE.</p><div style="clear:both;"></div>
