altbeacon / spec Goto Github PK

I am trying to get all beacons those are in my range, and for that I am using the "beaconManager.getRangingNotifier().didRangeBeaconsInRegion(Collection arg0, arg1);" method. I am trying to use arg1 parameter as a region consisting of all the beacons so that I get the 'beacons' collection filled up with just the beacons that are in proximity.

But I am not able to create a region with multiple beacons. When I use the region constructor with three ideantifiers and fill up those values with UUID, Major & Minor values of a particular beacon it is able to match. But whenever I am using the constructor with List version, and pass all the UUIDs, no matching happens. Please provide some guidance.

Hi I am new to developing this technology. I am struggling to whether to use the old library or the now one. As I see the older library code I can understand some of it but when I tried to transfer to newer version of library, I encounter problems and I have been looking for answer lately but no luck with it.

first, at the older version there is a function that you can get "getProximity" but I can't find by new.
secondly, to get the beacon's name, at the older version, you can use "getProximityUUID" where at the newer library, "getId1" can be printed out as string?

I am using android to develop. These are the questions that is in my mind for long time.. If possible please help me out these questions.

Can altbeacon transmit and receive beacon simultaneously?

i have in my logcat :

08-05 17:21:45.171: D/BeaconParser(15973): This is not a matching Beacon advertisement. (Was expecting be ac. The bytes I see are: 0201061aff4c000215da56717d0e334712b3ede61802d24b18256e0c4fb604086e39361106a6da37dec19afc80944ad8a80262c2be020a00000000000000

How i can parse this data, with the class that you provides:

BeaconManager.getBeaconParsers().add(new BeaconParser()
.setBeaconLayout("m:2-3:beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));

i dont understand.

Please help.

Cheers!!

We have hardware that is transmitting 4-6 Beacons per second (confirmed with BLE sniffer) which we are using for undisclosed purposes. I have written an App using this AltBeacon API, however, I only receive 1-2 broadcasts per second. Even when I use the "Locate" Android App written by radius Networks, I see the same results, 1-2 broadcasts per second.

My question is: Is this a limitation in the AltBeacon API? Is there any way to adjust this or receive 4 beacons per second with the same ID1 (but different ID2 & ID3)?

While having an open standard would be great, the true brilliance of iBeacon is the integration into the OS. Maybe if you can get Android to integrate this will have a chance, but I'm afraid that's the only way.

Testing Android and iOS devices side by side, using 7 beacons on their "loudest" setting (-63 Tx), we find that -

• Both Android and iOS devices show similar RSSI signal readings at various distances
• With the formula used on Android version the same RSSI reading is converted to a very different distance on Android as compared to IOS (see table below)
• RSSI readings were similar on 3 Android devices used for testing (Nexus 5, Nexus 4, Samsung Galaxy S5)
• In fact Android device never showed distance further then 5 meters away for any RSSI which is logical based on the trend you see for Android in the table below

Distance, iOS (RSSI)
0m (-35), 1m (-63 = Tx), 2m (-70), 4.5m (-75), 10m (-80), 25 (-90)

Distance, Android (RSSI)
0m (-35), 1m (-63 = Tx), 1.2m (-70), 1.6m (-75), 2.7m (-80), 4 (-90)

Is it possible to either find a way to adjust parameter in the formula to mach iOS calculations closer or use liner approximation based on the experimental data above

Hi,

Someone can give me the layout for Accent beacons.
Or, how can i determine it.

Thanks,

What is the "AD Flags" field depicted "BLE Advertising PDU" picture?
I cannot find any information regarding this data field in neither the Bluetooth specification or via internet searches.

As i read the picture, it seems like it is part of the ADV_IND PDU packet but no information points to ADV Flags being a part of this packet.

Hello,
I would like to report that the link to the Raspberry library does not work. A few months ago I downloaded a version and unfortunately I am scanning the device very slowly. As if buffer in Raspberry 3 blocked. Does anyone have a similar problem?

Hi

Just wondering what the purpose of the "Beacon code" is. Why is the big endian representation of a seemingly random hex needed in the advert packets?

Thanks

I would like to have a UI and a Service to detect beacons. AltBeacon library will be implemented in Service.
Can I get the Beacons notification to UI when UI is in foreground and background?

Hello,

Do you have any experience with passing hundreds of beacons to BeaconService using startMonitoringBeaconInRegion or startRangingBeaconInRegion for each? Does it produce ANRs and is impossible to handle or should it work fine according to your tests?

Best Regards
MG

Not sure if I'm the only one with this issue, but it would be awesome if I could turn off the onClientRegistered() and onScanResult() logs. Or just all logging associated with the library. It makes debugging other features nearly impossible with the logs constantly filling up.

I am receiving signals from an unknown Bluetooth device with the transmission looking like this:

1BFF75004204018000BC1485CB02D4BE1485A9E44F01000000000000

It APPEARS to be an AltBeacon - it has 1B FF at the beginning and also has the correct number of characters.
However, the Tx Power (Reference RSSI) value is always zero. This message is transmitted about once per second and no bits ever change at all.

The manufacturer code corresponds to Samsung but I guess it is coming from an office nearby as we haven't been able to locate it. Signal strength is pretty constant between -93 & -98dBm so it doesn't appear to be moving like a mobile phone would.

Is there anything in this message format that means it ISN'T an AltBeacon? We would like to exclude it based on some parameter but from what I can see in the spec is does match, with the problem of not giving us any Tx Power in order to calculate distance.

Give me guidance step by step to integrate AltBeacon in our android project
Your Guidance will be appreciate.
Thanks in advance.

I've been developing https://github.com/CharruaLabs/AltBeacon for several months, with many dudes using it. I find it weird you chose to name your open beacon spec the same as this project.

Hi,

could you provide a brief summary on how you plan to provide feature parity with iBeacons on iOS? To clarify, I mean feature parity between an iOS app using iBeacons and an iOS app using AltBeacons. Sorry if I missed this but I haven't seen anything on this on your web site... In particular, I'd like to know how you plan to access the raw advertising data (or how will you do without it, if you don't plan to) and how will the restart-into-background feature work.

As a side note, you might want to clarify on your "Examples" page that the CharruaLab project is just an unfortunate name collision, not a weirdly different 3rd party implementation of your beacon spec. It took me a while to figure this out, especially since that's the only iOS related link I could find...

Thanks,

When running app, its looks good and scanning.
Pushing lock-screen it stops scanning. (Not killing the App)

Open App:
[log] {"region":{"identifier":""},"beacons":[{"proximityUUID":"E2C56DB5-DFFB-48D2-B060-D0F5A71096E3","major":0,"minor":0,"rssi":-71,"accuracy":1.68,"proximity":"near","txPower":-59,"macAddress":"AC:23:3F:A9:21:7B"}

Lock Screen:
[log] {"region":{"identifier":""},"beacons":[]}

It must work in lock-screen for my usage.
Any idea?

Hi,
I'm finding a glossary with the detail / description of each data that can be retrieve when a beacon is detected. Do you know a good one?

Hello,

My question is - should you use a SIG organizational identifier for the mfg code if you are generating ALT packets using Bluez?

For example, I have a Broadcom BT4.0 adapter - its MAC state that it is part of the Broadcom OU. I obviously don't manufacture the BT chip, but the device will be distributed under another company. Should that company apply for a CIC and use that in the mfg field?

Thanks!

This issue was opened against the wrong repo

Hi there,

Is there a way to perform a scan & a transmission while the screen is off knowing that the app will not be on the AppStore and i have a DB with all the UUID used?

Hi, I have an app derived from the beacon reference app, neither of which detect beacons when the app has been killed despite the service starting (I can see that in the application manager). It all works great with the app running in the background it is simply if the app is killed that the notification that I want to display is not. The manifest is all set up as I can see the service start and stop on the intent actions. Is there something else that needs doing to get this to work. The reference app doesn't seem to do this either. I am running a Galaxy Alpha (4.4).

CODE SNIPPETS:

mBeaconManager.setBackgroundScanPeriod(1100l);
mBeaconManager.setBackgroundBetweenScanPeriod(1100l);

public void didEnterRegion(Region arg0) {
if (mMonitoringActivity != null) {
mMonitoringActivity.didEnterRegion(arg0);
}else{
showNotification() ; //this function is supposed to put a notification in the notification tray and does so if app in background running but not if app killed.
}
..

Manifest (merged)

Will this allow a flavour of beacon to be broadcast from iOS as well as Windows phone and Android? Although I see the Windows and Android libraries, is an iOS library under development?

As a developer, I want all three phone platforms to be capable of broadcasting a beacon so that I can use a Raspberry Pi to detect them - so if Apple are playing up with the iBeacon spec, I'd be happy to move to this spec if it supports all three platforms.

Will AltBeacon do this, also be adding an iOS library?
I'd also like it to work using Xamarin on all three libraries, so will a Nuget package be created for Xamarin Forms?

*** If someone creates three C Sharp libraries (one for each platform), with an example of each, I'd be happy to help by taking those and creating a Nuget package for Xamarin Forms

Using Altbeacon lib, I can see the beacons that I am looking for.
@OverRide
public void didEnterRegion(Region region) { ...}

But I also need to read AD Flags such as following, for example:
02 # Number of bytes that follow in first AD structure
01 # Flags AD type
1A # Flags value 0x1A = 000011010
bit 0 (OFF) LE Limited Discoverable Mode
bit 1 (ON) LE General Discoverable Mode
bit 2 (OFF) BR/EDR Not Supported
bit 3 (ON) Simultaneous LE and BR/EDR to Same Device Capable (controller)
bit 4 (ON) Simultaneous LE and BR/EDR to Same Device Capable (Host)

Is there an API in Altbeacon lib to read the Flags?

Thanks,
Yong

The Bluetooth SIG has a process called New Work Proposal (NWP) and that should be used to create a beacon standard. It will allow to define Extended Inquiry Response (EIR) and Advertising Data (AD) types for beacon data.

Using the EIR and AD manufacturer field is not helping since you need to fill in Bluetooth SIG assigned manufacturer ID. If everybody fills in their own this is still not interoperable.

Provide the same semantics as in NFC and QR Codes: A free text string (e.g. 100 bytes) for URLs (http:, https:), phone numbers (tel:), SMS (sms:, smsto:), location (geo:), e-mail (mailto:) etc.

The most important would be URLs. Shortened URLs would easily fit in the 20 bytes payload.

Cheers,
Anders

What is the difference between Beacon.Builder.setTxPower and BeaconTransmitter.advertiseTxPowerLevel? I did not see any value vanges for these properties in the documentation. How do you go about increasing the Tx power of the advertisement beacon?

When app swipes from task switcher I am unable to get the Beacon ENTER/EXIT NOTIFICATION. I have implemented BootstrapNotifier in Application class & made an launcher activity as 'singleInstance'..Please let me know Is this library will work when app is killed or not?

Hi, I've an app working stable on android 6.0 and 5.0, it detects beacons in region even if the app is killed. But when i install the application on Sony Z5 that has android N version, it only detects on foreground. Below is the logs when application is killed. Scan started but no detection occurs. Is there a known bug on api 24?

I installed Android Raidus Networks Locate app and try to locate my iBeacons (one beacon is from estimote hardware and another is from Raidus Networks's iPhone Locate App".

why? Does this spec need new hardware's implementation?

I am asking this cause in google play I found it saying not compatible with my device. So is it true? Or is there an android version limit?(I am currently running 4.1.2)

I am trying to analyse the packet data I am receiving from two different AltBeacons (RadBeacon and easiBeacon). I have compared the received data with the sepcification and can match all except one byte.There seems to be one more byte than expected between the BLE header and the AltBeacon Advertisment. Since both beacons send the same format I could just ignore it I know, but it would be nice to know what the issue is. See below for the data packets. Any help would be appreciated.

As currently the Library offers only kind of a Beacon mode, how can I actually publish services? Is there intention to build up GATT mode in the library?

Thanks

Is it possible to set specific a address for BLE Beacons? Beacon.Builder.setBluetoothAddress does not seem to set the address seen by other devices.

Hello,
how come Beacon getServiceUuid() is not a publicly documented method?

Igor

Is there any advantage to using scan periods on devices that invoke callbacks for every advertisement? That is to say, if I'm not worried about power consumption. I've noticed the stack getting into an error state (can't find callback) and beacons are not getting discovered so I figure less frequently we toggle start/stop scanning less likely to encounter issues.

For example, Android Things on Intel Edison, the stack provides every callback. Technically, per Android API you can tell the stack you want all callbacks in your ScanSettings, but having developed with Android Bluetooth for a while I've learned better. It's the wild west and observed behavior frequently contradicts documentation official.

I have limited funds and don't want to buy a tag to practice on if it is not compatible or of low quality. I am a UK based developer.
Thanks in Advance!

Mike

Attending Google I/O 2015? Radius Networks CEO Marc Wallace and Chief Engineer David G. Young will be on site. If you're there, too, we'd love to get together to hear your ideas and experiences using beacons on the Android platform. Please send us a note at [email protected] or via Twitter @RadiusNetworks.

I just implemented the Android SDK in our app for a proof of concept but am now wondering about what the Beacon or BEL story is on Windows Phone 8.1?

We are seeing the following Fatal Exception after hours of broadcasting an AltBeacon every 10s. Not sure if this is related to the AltBeacon Native Libraries?

Fellow AltBeacon Developers,

I'm seeing the following AndroidRuntime FATAL EXCEPTION: main in ADB Logcat after I RangeBeacons for approximately 8 hours. It appears to only happen when my app is in an area of high beacon congestion, IE in a lab etc. If it sits in a quiet area, we do not see this exception...

I'm not seeing any Exceptions in my code elseware nor am I seeing the above Exception. The App just dies and falls out of the sky without any warning.

Anybody have an insight as to what the problem could be?

Thanks

Keith

I have updated Android to 4.3 and manage to run the Locate app on my phone with phone bluetooth on.
Also I have a RadBeacon USB device plugged into a laptop (running windows) USB socket.

When I try to locate beacons on the app it just returns no result. (Visible beacons. None.....)
So what else do I need to set up to get it running?

AltBeacon is great, thanks for the work.

But I am facing a problem that the foreground beacon data is good,
but when app goes to background the beacon data is kind of broken.

Here is my test result, the test device is an iPad App and using AltBeacon.

when the App is foreground, the beacon detail is like this:

and after the App go to background, the beacon detail:

BTW, the service table is unbroken.

So, did I miss to setting something or Apple changed the BLE beacon data at system level?

I want to read the MNFG RESERVED byte form the beacons of RadiusNetwok x4. How to read this byte?

During working with altbeacon i have found that altbeacon with transmission power lower than 0 is giving multiple false entry/exit. Is there any way to fix it?
