I cannot build in Android Studio 3.2.1 with buildToolsVersion 28.0.3

I just extended BluetoothActivity in the new project and then I got:
java.lang.NoClassDefFoundError: de.greenrobot.event.EventBus.

Using the repo specified on git doesn't seem to work.
I don't know much about how the gradle dependencies are set up but I'm using the following:

repositories { maven { url "http://sfdn.ddns.net/maven2/" } mavenCentral() }

I noticed you use a different one altogether in the sample projects but that repo link seems to be dead as well

repositories { maven { url "http://192.168.1.99/maven2/" } mavenCentral() }

Hi All,

Can't we create class which can be used for Bluetooth connectivity implementation.

Instead of Bluetooth Activity & Fragment , we can use this class.

Currently I am using App compact so can't use Bluetooth Activity or Fragment.

Open for suggestions & improvement comments.

Best Regards,
Sajid

the lib and sample can't compilation or operation

Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {net.reixd.sample/com.ramimartin.multibluetooth.activity.EnableBluetoothDiscoveryActivity};

i can't found this class file in Android-Multi-Bluetooth-Library,how can I do

I'm looking to bind this project on Xamarin. I would need the jar to do so, thanks.

How we can rely on this library if there is no single unit test to cover it? Do you trust it? You can't.
Please add unit test so one can easy prove if functionality is as declared. Thanks

Hi,
When I try to run the application having 1 client, I am able to detect the device and pair it with the server successfully but getting an error on the client side, "Client connexion error" and it goes in an endless loop.
And when I try to debug I get the below error.

Can anyone help me out with this??

Thanks.

Marshmallow device do no make server and dont even connect as client..!!

When I try to import your library I get:

Error:(25, 13) Failed to resolve: com.ramimartin.multibluetooth:AndroidMultiBluetoothLibrary:1.1-SNAPSHOT

Any ideas?

I am facing R file error and abc_textfield_search_default_holo_dark.9 image problem

why that is coming for all the source codes downloaded from GitHub

I see there is a method for sending directly to one device:
public void sendBytes(final String adressMacTarget, final byte[] message);

But i cant figure out where to get the mac address.

Isn't there an thrown event that giving me the mac address of the device that has connected to my server?

I am trying to create a client- server network using this code and I am able to run the application but I am unable to scan the near by devices and unable to connect the clients to server and send the message.
Need help in solving this issue.

The sample code provided doesn't seem to work. I am attempting a BT connection between a Android 5.0 and a 4.2 using the sample code provided; however, I am constantly thrown the following error trace:

Server: Here I declare four BluetoothSockets. Because accept () is a blocking operation, once the connection is successful, it will return to BluetoothSocket, and then continue to wait for the next connection. In this way, we have achieved multiple connections. UUID is the identifier of the server. After obtaining the BluetoothSocket, we can perform related operations to obtain input and output streams. To communicate with each other. by there

I need to connect to a Bluetooth device HC-06. I can connect as a client with the onDeviceSelectedForConnection ("20: 14: 04: 09: 17: 48") function. It would be possible to connect as Server?

The works they try and not worked is mBluetoothManager.createServeur ("20: 14: 04: 09: 17: 48");

You know someone who has tried to do this? Thank you. Excuse me for my bad english! Greetings and excellent library

can you send files using this library?

I tried pretty much every possible thing I came up with to stop it but...

Once called "createClient(mAddressMac) it starts a new Thread, which constantly tries to establish connection with chosen device. I found myself helpless in stopping it.
As I read into you library it should stop when disconnectClient() or even resetClient() is called but it won't. It keeps trying to establish connection, even if you completely turn off Bluetooth, call "closeAllConexion", try to create Connection with another "server" or change your mode from client to server.

Is there something that I'm missing? :-(

Hi, I wanted to ask if it's possible to stream music to multiple Bluetooth speakers.

Thanks in advance and Best regards.

Using
android.provider.Settings.Secure.getString(mActivity.getContentResolver(), "bluetooth_address");
is no longer allowed for 7.0+ devices so the current method of using UUID's will no longer work.

I think the only alternative is to use a pre-set list of 7 UUIDS and listen for all on the host.
Then each client will have to try each UUID until one works or fail.
