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've a iOS 10 device in my work place and I got curious about it's bluetooth's weird behaviour. So.. I was playing around with my Android's Beacon simulator App and I noticed that every time I unlocked my IPhone and enabled the Bluetooth a new entry was immediately created in my android's near by beacon's list. Is there a reason for that?
UPDATE 1
- handoff disabled
- AirDrop disabled
- No open apps.
= still got a mysterious broadcast on my Beacon Simulator App.
UPDATE 2
Ok, I was digging into the subject and noticed that the iOS device is not being able to find near by devices in a standard bluetooth discovery.
In the other hand, near-by devices can detected the iPhone and when clicking on his entry in their result's list a popup for pairing shows up on Iphone's screen and as if it was magic the name of the device trying to pair shows up on the iphone's list that is always empty, in this case Huawei P9 but tested with a note 4.
I am the developer of Beacon Simulator. I just want to warn that the app is a Beacon simulator before all, not really a Beacon scanner. I added the scanning part because it was easier to do some tests, for the beacon copy feature and also for future developments.
What the scanner will show you is not necessarily a beacon, but any scannable Bluetooth Low Energy devices, connectable or not. Unfortunately, it is difficult to know if a device is connectable or not with the Android API, so the app lists everything.
Since the icon represents a standard Bluetooth logo, it means it is a signal not recognized by the app (here, it isn't an iBeacon nor AltBeacon nor Eddystone beacon). So either it is a non standard beacon, or simply a signal to advertise a possible connection to the device. When a connectable device broadcast its presence, the signal uses the same channel and protocol than the one used by beacons. A connectable device will advert itself as connectable, but as said, the Android API erase this difference, unfortunately.
So what you see is not necessarily a beacon, but maybe simply your iPhone broadcasting its presence as a connectable device. Maybe I should add some disclaimers in the app.
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 have read the docs about the BLE for iOS, and i could see that every device has its UUID instead of mac adress for the BLE.
My question ,in which there is no answer to on the docs, is- when you turn on the bluetooth on the device ( without opening any app) , so the device's bluetooth is on , what does it advertise then, and could I discover that device or get its UUID, while his bluetooth is on,but without any app that is open.
I am pretty sure that when the BLE is on, you can discover that device, or awake him, but I wonder what data can I get from him while its on without an app .
(same for Android.. )
iOS does not advertise any Bluetooth Low Energy services that are visible to another iOS device without an app running. Once an app advertises a service you will see additional services available - device information, time service, battery level.
If you are using different Bluetooth hardware to scan then you may see some advertisements without an app but the reported UUID of an iOS device changes every 15 minutes for privacy reasons - See this answer - Corebluetooth, How to get a unique UUID?
Can you pair a bluetooth LE device in an iOS app, i.e. not via Settings. Trying to make it easier on the user to pair with a specific device.
If so how?
You don't pair Bluetooth LE devices through system settings. Generally you don't pair with Bluetooth Low Energy devices at all. The only time that pairing is required is when the device has an attribute that is marked as encryption required - attempting to read this attribute will trigger a pairing process, but before you can read you need to discover and connect to the device.
Discovery and connection is handled by the Core-Bluetooth framework.
The Core Bluetooth Programming Guide goes through the steps required to use a CBCentralManager to discover and connect to a BLE peripheral.
According to the BT SIG Security Manager documentation you can pair/Bond ble devices if they respond to the message that is.
You can also wait and do it as previously explained from the peripheral side. Some devices like HipKey does this automatically when connecting first time.
Look at BTSIG Security Manager specifications.
On Android this also works from BT settings menu IF the peripheral supports it.
Bonding and Authenticating are usually confused but om most platforms it means the same.
A good way to try this out is by buying the TI ble development kit. Its cheap. It comes with a USB dongle and SW which can be used to initiate pairing like from the settings menu.
To do it from iOS just connect and read a known encrypted characteristic.
Cases where you want to "pair" (remember a Bond) includes Pulse meters, hearing aid, keyboard and other private units.
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.
