Mobile device model and OS version -- Nexus 5, API 23
Android Beacon Library version -- 2.3.5
I have a sensor tag from TI(Texas Instruments), and the firmware is TI provided. The same 2541 chipset is used in all beacons. I try to detect it using this library, it comes inside the didRangeBeaconsInRegion() callback but it prints beacons.size to be zero size.
Now, what changes I need to do, to get this chipset detected?
Just for further information, there are free apps in playstore named (iBeacon detector) which detects this chipset.
Any help will be highly appreciated.
Thank You
A few points:
The Android Beacon Library is designed to work with Bluetooth LE Beacons, not non-Beacon BLE devices. A beacon is a specialized BLE device that continually broadcasts a unique identifier. If you need a more general purpose BLE functionality, the library may not be a good fit.
The TI Sensor Tag must be loaded with specific firmware to make it broadcast as a beacon.
There are many beacon formats including AltBeacon, Eddystone and iBeacon. If your BLE device is transmitting as a beacon you need to know which one it is transmitting.
By default, the Android Beacon Library only detects beacon transmitters sending the AltBeacon format. To detect other beacon formats, you must supply a BeaconParser for that format. A Google search will easily find the Parser expression to configure based on the format the beacon is using.

I used swiftUI, and it was confirmed that the header bridge was also working properly.
As you can see in the image, the altbeacon is scanning fine,
but not the ibeacon.
I set the layout like this
setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25")
, is there any problem? please check.
I tried changing the layout like this, but it didn't work.
setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24")
The OP has set up beacon scanning on iOS using the AltBeacon iOS Beacon Tools
The above tools help iOS scan and decode Eddystone, AltBeacon and other BLE beacon formats using iOS CoreBluetooth APIs under the hood.
However, the above tools cannot detect iBeacon because iOS blocks the underlying CoreBluetooth APIs from getting scan results for iBeacon advertisements. In order to detect iBeacon you must use CoreLocation APIs alongside what you are already doing. While this is duplicative, unfortunately Apple requires this duplication by sandboxing iBeacon from other BLE advertisements.
I want to develop an iOS app that will work as Beacon receiver which will get broadcasted device UUID's from surrounding distance via bluetooth low energy(BLE) device supported coverage distance.
I am following this tutorial https://www.raywenderlich.com/152330/ibeacon-tutorial-ios-swift. This tutorial provides a device to work as Beacon via adding Device UUID's, but i need to get those device UUID's automatically.
How can i do that? Is it possible using CoreLocation and CoreBluetooth services?
I have been trying to connect to a Jaalee beacon using altbeacon library without success.
The service UUID is 0x00001532-1212-EFDE-1523-785FEABCD123
What is the correct setting for setBeaconLayout in altbeacon?
For example for another type of beacons that is
beaconManager.getBeaconParsers().clear();
beaconManager.getBeaconParsers().add(new BeaconParser().
setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));
I have searched everywhere and I cannot find it. Thanks
** UPDATE **
I have checked using a program scanning for bluetooth devices and indeed it is a Jaalee device.
The bluetooth device has name "jaalee"; ScanRecord is
[mAdvertiseFlags=4, mServiceUuids=[0000fff0-0000-1000-8000-00805f9b34fb], mManufacturerSpecificData={}, mServiceData={}, mTxPowerLevel=0, mDeviceName=jaalee]
The fact that you can detect the device transmitting a Bluetooth LE Service UUID, but cannot detect it with the Locate App means that:
The Jalee device is not transmitting a standard AltBeacon or iBeacon frame, both of which are detected by the Locate app.
The Jalee device is connectable, and might be configurable if you can find a Jalee configuration app. This may allow you to configure it to transmit the standard bracon frames described above.
I am using a Gimbal series 10 device configured in iBeacon mode using one of the AirLocate UUIDs (the first one - E2C56DB5-DFFB-48D2-B060-D0F5A71096E0). When I use iBeacon Locate on my Android phone, I can see the Gimbal broadcasting the correct UUID. However, when I try to use Apple's AirLocate demo app, it is not working in trying to find the iBeacon. I also cannot find it in the iOS version of iBeacon Locate, by the same company, Radius Networks.
I am using the beta version of Xcode / iOS.
We have internal apps that would like to use the micro-location features that iBeacons allow, and I'm trying to put together a quick proof of concept. Unless I can get the iBeacon distance using the sample code in AirLocate, I cannot proceed. Any help or experience with this would be greatly appreciated.
Two suggestions:
First, Look closely to verify that have every single character of that ProximityUUID entered as above in the Gimbal configuration. If even one character is off, it will not be visible in AirLocate or the iOS version of the Locate for iBeacon app.
The Android version of iBeacon Locate shows all iBeacons regardless of ProximityUUID, so it will still be visible in the event of a configuration issue.
Second, there is a known bug in iOS 7.1 CoreLocation where iBeacon detections can stop entirely until you reboot your phone. Try rebooting and see if the beacon starts showing up in both applications on iOS.
We have an existing iPad app that we are adding iBeacon transmitting capabilities to. I am unable to transmit an iBeacon signal. I won't provide the code at this point because I've also tested the Apple AirLocate example and the Radius Networks Locate iB app as a transmitter and in both cases the iPad won't transmit a beacon.
We tested with iPhone 5 devices and they can both transmit and range beacons.
What could be the issue with our iPad test device that it won't transmit? It can range beacons from the iPhones just fine.
BT is enabled. Location Services are enabled and approved for the apps in question.
Two likely causes:
The Proximity UUID of the iBeacon transmitter is not configured with Locate for iBeacon or Air Locate. Locate cannot see new iBeacons with unknown Proximity UUIDs. Even if the configuration is off by only a single digit, the iBeacon will be invisible.
Many users have reported recently that their phones are getting into a state where they cannot see iBeacons, and a reboot solves the problem. See here for more details.
How do you detect the iBeacon, actually?
I once encountered the problem that CLLocationManager#startMonitoringForRegion: did require a certain period of time, until the regions were updated and a region was ranged. So CLLocationManager#requestStateForRegion:...
In either way. What I first did to validate that beacons were emitting/sending correctly (not receiving): I downloaded a common Bluetooth Scanning-App and checked, whether the App is able to range the emitted beacon. Could you verify this at first? Maybe the iPad Air is sending correctly, but the receives do not range the beacon yet.
