Sounds like you are on the right track. In general you are correct that an app needs to be in the foreground to fully use iBeacon capabilities. A few specifics on your three main questions: Your mall use case can work with a couple of limitations. (a) you have to conserve your CLBeaconRegions by having … Read more
Note: This only works in Mavericks, it does NOT work in Yosemite. Mavericks doesn’t have the iBeacon support in Core Location that was added to iOS 7. However, Mavericks does now have the ability to act as an BLE peripheral device. Given that an iBeacon is basically a peripheral it should be (and indeed is) … Read more
EDIT: The library below has been moved here: https://github.com/AltBeacon/android-beacon-library I have ported the iOS7 iBeacon SDKs to Android, and was able to see standard iBeacons and estimate their range. The code is available here: https://github.com/RadiusNetworks/android-ibeacon-service For this to work, you need Android 4.3 which introduced the Low Energy Bluetooth APIs. You also need a device … 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
From what I understood of the API is that there is never a guarantee on actual distance, you should not use the readings to be considered an accurate measurement. The proximity is rather used to determine the relative distance between different beacons so that you can respond accordingly based on your applications requirements. With that … Read more
You need to install libbluetooth-dev package for compiling your code sudo apt-get install libbluetooth-dev That should install the bluetooth header files.
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
Standard CoreBluetooth advertisements can broadcast while the app is in the background, but not if they were started with CLBeaconRegion dictionary. The workaround is to ditch CoreLocation framework altogether and create your own proximity “framework” using only CoreBlueTooth. You still need to use the appropriate background specifiers in the Info.plist file (e.g. bluetooth-peripheral and bluetooth-central). … 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
