Once you've set the calibrated power, if you change the transmit power you'll need to re-calibrate.Īlso note that your distance values can vary quite a lot. Make sure not to confuse the calibrate power value with the transmit power setting. Save your changes, and you should be all set. Note the RSSI value it returns, then tap back and enter that value in the Calibrated Power field. If you are using Eddystone the phone should be at 0 meters. If you are using Altbeacon or iBeacon frame types the phone should be 1 meter away. Tap on the beacon result in the app, and tap the menu icon in the top right. Once you see the beacon you want to calibrate, enable connections on the beacon (in the case of the Radbeacon dot, hold the button down for a couple seconds. With the app open, and the beacon on, hit scan. If you're using the Radbeacon dot, you can configure the advertised RSSI using the Radbeacon app (link is for the Android version). When configuring Eddystone broadcasts, the picked calibration value will automatically match the advertisement's transmission power."ĭavidyoung is right. "The txPower calibration for Eddystone broadcasts is done internally by our beacons and SDKs. The following is how the beacon's settings (in the owner app) looks like: I cannot specify the RSSI value at 1 meter, I can only pick one of the Transmission power (dBm and distance). The phone was 1m away from the phone, and I got the following results: I made a measurements with the app with the Android Beacon Library. I thought it was due to the power of the signal, which I tried to change but it wasn't the solution, since it was broadcasting the maximum power.Īnybody with the same problem that found a solution? I did an app with that tutorial and when measuring the distance it tells me that the one that is 0,2 m away is 1.6m away, the one that is 10m says is at 70-90 m away and the other at 7m is at 40-60m. I tried to look for a solution here, but seems like everybody gets a better distance. With this, while sitting on a corner i have one in front of me (less that 0.2m) the other one at 10m (aprox, that's the diagonal of the room) and the other one at 7m. I have read that it gives some fluctuations but I have three beacons in a room that is 7m x 7m one in each corner.
