https://devzone.nordicsemi.com/f/nordic-q-a/57090/rebroadcasting-advertisements-unintentionallyQUESTION(s): Is there such a thing in BT spec that allows for a device to rebroadcast advertising data for another device? Sort of like a flood mesh. Could it be iBeacon specific and only occur with Apple devices?

Also, it would not make sense in most cases, particularly for iBeacon where RSSI is intended to be used as an indication of proximity.</p> <p>I think you need to look for another explanation of the change in RSSI. How do you measure the RSSI? In many cases, the RSSI is found by just detecting the power in the particular RF band at the time of reception. If this is how you measure and do not take the signal quality into account, you could get a high RSSI reading with a very high noise/interference power. Or perhaps you measure the highest RSSI over a larger band? Or it could be something else entirely...</p><div style="clear:both;"></div>
