ibeacon

I'm trying to estimate the distance from an iOS device to an iBeacon. I am aware that distance estimation is not super accurate, and I am also aware of this formula: https://electronics.stackexchange.com/questions/83354/calculate-distance-from-rssi I have found, through some research, that an iBeacon's BLE advertisement in fact contains data that represents the calibration value. That is to say, the RSSI determined at 1 meter away is actually broadcast by the beacon for all to see. Now, I think the iOS must internally use this information to determine the Near, Far, Immediate, and Unknown

First: I have an iPad Air 2, and an iPhone 7. For further reading we estimate that the app is active and open on iPad and in background mode on iPhone. The app is exactly the same, even with same Bluetooth Service UUIDs and same DataLocalNameKey. I want to write an app that can advertise a bluetooth service in background and is able to discover this service (optimal in background too). As I already read I can't use apples beacon technology cause there it's only possible to get scanning/notified by beacons in near in background (I tested this, works fine) but not to advertise. So I started to

I want to post a notification when users enter into a region. However, I am very confused because of same two CLLocationManagerDelegate methods. How should I use the two methods properly? Some people say "didDetermineState" method is needed to start region observation if the app start in the region. Thanks, - (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region { [self sendNotification:@"didEnterRegion"]; } - (void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region { switch (state) { case

Now that I need my app to identify if a beacon belongs to iBeacon or Eddystone. So far, I'm successful in determining UUID,MajorId,MinorId of ibeacon by parsing the AD frame. 回答1: It's relatively easy to read the bytes of the advertisements if you know the byte offsets of all the fields. Two code snippets below show you how you can parse these out. The first shows how you can do this in your own onLeScan callback using the Android Beacon Library , and the second

Is there a way to make a browser aware of iBeacon devices in its proximity? Similar to the way HTML5 Geolocation is working... If not would this be something that can be achieved with a browser plug-in that can provide the detail to be consumed by javascript? Unfortunately, no. No web browsers have implemented any bridges between beacon detection and JavaScript. I don't think a plugin approach is possible on mobile browsers (either iOS or Android), because neither browser supports asynchronous communication between external apps and JavaScript in Mobile Safari / Mobile Chrome. The best you

It's all running pretty good, but i'm struggling with getting the app to run properly in the background. self.region = [[CLBeaconRegion alloc] initWithProximityUUID:self.uuid identifier: self.deviceID]; self.region.notifyEntryStateOnDisplay = YES; [self.locationManager startMonitoringForRegion:self.region]; So this is the basic setup and for my test app i want to show a local notification when my phone is in immediate proximity of the beacon. My problem is that it won't work

It's necessary that the service is advertised rather that simply discoverable on the peripheral because the use case requires the central (in BLE parlance) connect to the peripheral after being woken up by iOS (but still in the background) due to proximity to the iBeacon. Apps running in the background on centrals can only discover peripheral by available service rather than discovering all

I can assign new uuid, major, minor to any iBeacon devices I have. I'm puzzled at how the iBeacon devices know these configuration changed so that they can broadcast? The iBeacon devices can communicate to web server (this seems not make sense at all)? P.S.: I didn't call any Gimbal API because I set them to iBeacon type. Can anybody explain this? Thanks 回答1: Changing the identifiers of most iBeacons requires using an app that can talk to the beacon over
