beacon_broadcast's Issues

Set interval in advertising parms

Hi!
Thx for your job.
But fir my project there are not enough parameters to set the broadcast frequency.

Is this being solved somehow?

Setting the device name

Is it possible to set the device name from this package?

Problem: You are too good to be real.

I really like the projects you do and the way you coding!
Have nice day :)

Awesome Flutter

Very good fit for https://github.com/Solido/awesome-flutter and bluetooth section if you want to PR I'll merge. Thx !

Check whether a privacy manifest needs to be added

First of all, thank you for publishing such a wonderful package. Our project has been greatly helped by this package.

By the way, starting from April 2024, SDKs used by applications that are published to the Apple App Store need to specify a privacy manifest and digital signature.

I don't think this package requires any additions, but I'd like you, the developer, to confirm.

Apple reached out with the following:

I lead the Creative Pro Partnership Management team in Apple Worldwide Developer Relations. We manage the relationship with developers who create developer tools, photography, music, 2D/3D design, 3D and gaming pipeline, and production-focused apps and hardware.

As you may know, in June, Apple announced new features to help users understand developers’ privacy and data collection and sharing practices. These new features include privacy manifests and signatures, which we encourage all third-party SDKs to adopt to provide transparency to users and help secure the software supply chain. Third-party SDKs that impact user privacy will be expected to include a privacy manifest and signature, and starting in Spring 2024, new and updated apps that include these third-party SDKs will need to include their manifest and signature to submit to the App Store.

Here are some additional resources that may be helpful:

You can read documentation about creating a privacy manifest file.
Our User Privacy and Data Use page has details about requirements for developers.
You can watch videos about adopting privacy manifests and signatures for your SDK.

Flutter is tracking this in flutter/flutter#131940

Swift Version Error

Hi,

When I try to build for iOS, this error occurs:

beacon_broadcast does not specify a Swift version and none of the targets (Runner) integrating it have the SWIFT_VERSION attribute set. Please contact the author or set the SWIFT_VERSION attribute in at least one of the targets that integrate this pod

Why is this happening? Thanks!

Beancon Receiver

Thank you very much for your beacon_broadcast, it helped me a lot. Can you develop a beacon_receiver plugin? Thank you.

Noob Question - Broadcasting Eddystone UID

Heyo,

I have to advertise as Eddystone UID. Is this possible using this library?
(Please excuse the noob question. I just starting reading into this beacon topic yesterday)

Eddystone broadcast issue

Hello,
I want to thank you for making this library. I am having an issue broadcasting my Android phone as an Eddystone beacon using the code below:

    BeaconBroadcast beaconBroadcast = BeaconBroadcast();

    beaconBroadcast
        .setUUID('39ED98FF-2900-441A-802F-9C398FC199D2')
        .setMajorId(1)
        .setMinorId(100)
        .setLayout(
            BeaconBroadcast.EDDYSTONE_UID_LAYOUT) //Android-only, optional
        .start();

I am getting the following error:

PlatformException (PlatformException(error, Beacon has 3 identifiers but format requires 2, null))

Any help regarding this would be much appreciated.

Thank you :)

Could not broadcast on Android

I used this lib to broadcast and used other libs to scan beacons.
I tested on real devices:

• On iOS: I can see other ios beacons.
• On Android: I can ios beacons.

I used another android app (install from PlayStore) to broadcast and my app can see that device. That means there is something wrong on the broadcast from my app.

BeaconBroadcast beaconBroadcast = BeaconBroadcast();

if (Platform.isIOS) {
      beaconBroadcast
        .setUUID('XXXX-...')
        .setMajorId(2)
        .setMinorId(102)
        .start();
    }else{
      beaconBroadcast
        .setUUID('XXXX-...')
        .setMajorId(5)
        .setMinorId(105)
        .start();
    }

Eddystone layouts broadcast.

BeaconBroadcast()
.setUUID('0000feaa-0000-1000-8000-00805f9b34fb')
.setMajorId(1)
.setMinorId(100)
.setTransmissionPower(-59) //optional
.setAdvertiseMode(AdvertiseMode.lowPower) //Android-only, optional
.setLayout(BeaconBroadcast.ALTBEACON_LAYOUT)
.setManufacturerId(0x00E0) //Android-only, optional
.start();

When i try to broadcast eddystone url by setting layout EDDYSTONE_URL_LAYOUT app produces error
PlatformException (PlatformException(error, Beacon has 3 identifiers but format requires 2, null))

While I have tried by unsetting MinorId then library throws exception of casting null to int not allowed.

Any solution/suggestion will be appreciated. Thanks.

Sample crashes when beacon is started

I tried running the sample program posted on pub.dev, however, when I ran it and started the beacon, it immediately crashed. I have only seen this kind of behavior when a permission needs to be granted; is there something I need to add to my Info.plist? If so, please add it to the documentation. I am running it on an iPhone 8.

Issue with building for iOS

Hi 👋

First of all thank you for the effort taken into this library!
I have an use-case in wanted to try it out immediately, sadly I have errors in a clean flutter project, running on my iOS device. I think it has to do with the project setup it's using objective-c instead of swift.

Background

Is the beacon also advertised if the app is in the background?

V2 Embeeding issue

The plugin beacon_broadcast uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration

custom layout

how to set custom layout and data fields

main.dart

Please my friend,help me!I need main.dart document because I need buid apk.Please help me.

Where are the data fields?

Hello!

Looking into the Android Beacon Library I can see that there is a "setDataFields" method but beacon_broadcast doesn't exposes it to us.

Being so, how can I set the data my beacon will broacast, like an url or a simple string?

Thank you for your time and effort onto this library!

about connecting BLE

Hi, I would like to know that is it possible to connect from another device to the device that is advertising with this library?

iOS - [CoreBluetooth] XPC Connection Invalid

Greetings,

First of all, thank you for providing this library for the general public. Once the app has launched, I'm getting an error in the Xcode console that says: "[CoreBluetooth] XPC connection invalid"

Below is what I'm using hardware/software wise:

• macOS Catalina v10.15.4
• Xcode v11.5
• Flutter v1.17.1
• iPhone 6S Plus -- iOS v13.5

I also made sure to add the NSBluetoothAlwaysUsageDescription and NSBluetoothPeripheralUsageDescription permissions to the info.plist file.

Android - X

!Please understand that I am not good at English so I am using a translator.

IOS = O Android = X

IOS works fine, but not Android

If you look at the logs on Android, it says that it is normally transmitting BLE signals, but it does not transmit actual BLE signals.

-Test Device = Galaxy S7, Galaxy Note9

Running with the sample file provided by the BLE library developer Github results in the same phenomenon

What kind of range can we expect?

I was wondering what the range of the beacon would be if I used this library. What variables would affect the range of the broadcast?

The library does not work on Android 12

Any solution to this error, it won't let me install the application in android 12

Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackageLI: /data/app/vmdl1325317315.tmp/base.apk (at Binary XML file line #90): org.altbeacon.beacon.startup.StartupBroadcastReceiver: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present]

@pszklarska

Thank you for the development of the library.

Broadcast is not working in example app

Hello,

Broadcast is not working in the example app. Compiles fine, but when I click Start button, beacon is not transmited. No errors in runtime logs.

iOS: 16.5
flutter: 3.0.5
beacon_broadcast: 0.3.1

Function .setMajor() isn't working iOS Platform

Ok so I configure my environment with no problems whatsoever, there's a bug when I'm trying to configure the Major before starting the broadcast in iOS Platform.

beaconBroadcast
            .setUUID(uuid)
            .setIdentifier('com.example.com')
            .setMinorId(0)
            //.setMajorId(100)
            .setTransmissionPower(-59)
            .start();

So when I uncommented the line with the function major the app never get running I can't get any feedback from the app.

Edit:

if (Platform.isIOS){
        beaconBroadcast
            .setUUID('$uuid')
            .setMajorId(0) 
            .setMinorId(0) 
            .setIdentifier('$uuid')
            .setTransmissionPower(-59)
            .start();
        debugPrint('iOS');
      } 

just close it after updates and review the code I didn't notice more issues I have a hard time back then but now is fully working. this is the code I have right now.

[Android] Multiple event broadcasting

On Android, Beacon is broadcasting different values multiple times without any user input. On iOS device, it is working fine, as expected.

I have also added the logs while any event is broadcasted. On any user input, the logs are printed, but after that when the frequent events are broadcasted, no logs are printed.

Cannot scan uuid of beacon using flutter_blue package

Hello!
I am trying to scan for ble beacons implemented using beacon_broadcast flutter package. I am using a flutter app that implements flutter_blue package, as my beacon scanner. But the scan result does not show any UUID. However when I use Beacon Simulator app available on playstore for scanning, it shows the uuid of my beacon.Below is the troubleshooting method posted on flutter_blue page. So is this a issue I need to check in beacon_broadcast package or flutter_blue package? And if the change is needed in beacon_broadcast package where should it be?
"Troubleshooting--
Scanning for service UUID's doesn't return any results
Make sure the device is advertising which service UUID's it supports. This is found in the advertisement packet as UUID 16 bit complete list or UUID 128 bit complete list."

Identifier seems to be required on iOS

Running the sample app on iOS resulted in a crash, I added setIdentifier and there is no more crash.

The logs for the crash :

Error Handling in Dart

Hello and thank you for making this library.
I currently have an issue where is an error occurs, the error is not passed onto Dart (i.e. can't catch it using try, catchError, etc), but appears on the console:

Performing hot reload...
Syncing files to device blah-blah...
Reloaded 1 of 512 libraries in 809ms.
D/BeaconParser( 7318): Parsing beacon layout: blah-blah-blah
D/BluetoothAdapter( 7318): isLeEnabled(): ON
D/BluetoothAdapter( 7318): isLeEnabled(): ON
E/BeaconTransmitter( 7318): Advertisement start failed, code: 2

Just passing the error code as a return variable (instead of Future<void>, then await/then) would be fine for my use case, but it if you have the time to do it, please change the code so programs can catch the error.

Here is a Stack Overflow question about the same issue.

Thank you in advance.

How can I make it working in Flutter v3

Thanks,
