It cannot be done without user interaction. The only option is you can generate a push notification to tell the user to bring the application to foreground. This is from the Apple documentation about this issue: When the operating system delivers push notification (iOS or OS X) and the target application is not running in … Read more
Check if your methods are implemented in the following way. In viewDidLoad, start moniotoring at the end self.beaconRegion.notifyOnEntry=YES; self.beaconRegion.notifyOnExit=YES; self.beaconRegion.notifyEntryStateOnDisplay=YES; [self.locationManager startMonitoringForRegion:self.beaconRegion]; after monitoring start, request state for your defined region – (void) locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region { [self.locationManager requestStateForRegion:self.beaconRegion]; } after state is determined, start ranging beacons -(void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region { if … Read more
Unfortunately, the official answer from Google is no, the Nexus 5 no longer supports advertising. We introduced BLE peripheral mode in Android 5.0 Lollipop. Nexus 6 and Nexus 9 are the first two production Nexus devices that support BLE peripheral mode. Due to hardware chipset dependency, older Nexus devices (4/5/7) will not have access to … Read more
YES This is possible on Android 5+, and you can find open-source code for transmitting as a beacon in the Android Beacon Library. There is also a full-featured version of a beacon transmitter in the Beacon Scope app in the Google Play Store. Here’s an example of transmitting iBeacon with the Android Beacon Library: Beacon … Read more
I have been making some experiments to get a precise position using three beacons. Results of trilateration Unluckily, the results were very disappointing in terms of quality. There were mainly two issues: In non-controlled environments, where you can find metals, and other objects that affect the signal, the received signal strength of the beacons changes … Read more
Yes, it’s possible and should be automatic. After you have created a CLBeaconRegion and started monitoring on it, Location Services will keep track of whether your phone is in or out of the region, even when your app isn’t running. If you app isn’t running during a transition, iOS will launch your app into the … Read more
We have received many reports at Radius Networks of phones stopping detecting iBeacons and requiring a reboot or turning Bluetooth off and back on again to resolve the situation. Folks have reported this on iPhone 4S, iPhone 5s, iPhone 5c and iPads. I do not have any hard evidence that this is something that broke … Read more
Yes! You can use your Raspberry Pi to scan for iBeacons. We’ve put together a script below that does this, you can also do it yourself with these steps: Start a background process that does a bluetooth LE scan: sudo hcitool lescan –duplicates & With the –duplicates setting the scan will not ignore multiple packets … Read more
The distance estimate provided by iOS is based on the ratio of the beacon signal strength (rssi) over the calibrated transmitter power (txPower). The txPower is the known measured signal strength in rssi at 1 meter away. Each beacon must be calibrated with this txPower value to allow accurate distance estimates. While the distance estimates … Read more
For an iBeacon with ProximityUUID E2C56DB5-DFFB-48D2-B060-D0F5A71096E0, major 0, minor 0, and calibrated Tx Power of -59 RSSI, the transmitted BLE advertisement packet looks like this: d6 be 89 8e 40 24 05 a2 17 6e 3d 71 02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 … Read more
