I am new to iOS and iBeacon.
I am confused about iBeacons's UUID, minor and major values of the device.
Is it possible to change/reassign the iBeacon device's UUID, minor and major values using any objectiveC.
Thanks in advance.

Yes that's possible, but it depends on the iBeacons you are using.
Most manufacturers provide a SDK which allows you to do stuff like that. If you know the commands that need to be send to change the iBeacon data of your beacons you can use Core-Bluetooth and do that yourself. But check if there is a SDK first, because changing UUID etc is the main task of these SDKs.
One example would be the Estimote SDK.
There is no way to do this with Apples built-in methods only. There is no "change iBeacon data" method. The bluetooth commands that have to be used to reassign iBeacon data depend on how everything is implemented on the actual beacon hardware.

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 am working on iBeacons. Trying to find out all beacons around me.
Like Android, in iOS, we cannot achieve this without specifing "UUID" while searching.
By using UUID, it is working fine.
is there any better solution to search all beacons around you, without specifying UUID?
I found one solution RNLBeaconScanner, which is in objective c. RNLBeaconScanner detecting beacons in ObjC but same beacons not detecting in swift.
Thanks in advance!
TLDR; You can't.
Longer answer:
If you specifically are working with iBeacons, you NEED to know their UUIDs, to pass a valid CLBeaconIdentityConstraint to startRangingBeacons method of CLLocationManager.
Core Bluetooth, which can be used for general BLE scanning, unfortunately cannot be used to detect iBeacons, because, well, apple doesn't want you to.
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.
We are generating UUID's using Ruby 1.9.3 (SecureRandom.uuid) and passing them to our iOS devices to monitor Beacons. We generate UUID's from iOS devices as well, but the iOS generated UUID's seem to be fine.
Here is the problem:
Server issued UUID, pulled in via API and applied to iOS device. Monitor Regions.
App is unable to monitor or range this Beacon using the supplied UUID.
We are using a the Radius Networks/AltBeacon library to monitor Beacons on Android devices, and the Beacon is able to be monitored and ranged fine with the same UUID.
iOS generated UUID's uploaded to the server work just fine. Only server/Ruby based UUID's don't work on iOS.
Does anyone have any idea why this might be? I'm 100% confident in my region monitoring code that it isn't an issue. When I output the UUID's, they are the correct format, and I'm not getting any errors at all from iOS. It seems like a legit UUID, but for some reason, iOS will not see it. Help!!!
In order to detect a beacon on iOS, the ProximityUUID you provide to the monitoring APIs must match that of a beacon transmitter. Your question suggests you are generating a random UUID in Ruby and then expecting to detect a beacon with the same UUID. This can't ever work, because there are so many possible UUIDs that the chances of ever finding a beacon matching a randomly generated UUID are next to zero.
Perhaps I am misunderstanding your question, but I wanted to offer this in case the issue is really this simple. The question says nothing about how you are transmitting with this UUID. Perhaps details about how this is being done might help clarify the issue. Also helpful would be an example UUID and a snippet of your iOS code that sets up monitoring.
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.
