Android Bluetooth Multiplayer

Hello, I'm currently evaluating bluetooth android solutions for a client's mobile VR project. This plugin was recommended to me multiple times, but after following this thread and the recent reviews of the plugin, could someone from LostPolygon please clarify if this is still actively supported? Thanks!

 

I bought this plugin, implement and add this in my live app and then developer abandoned us.
I got this crash report every day over 1000 times.

If anyone know the solution please let me know. I'll be very grateful.
Thanks in advance

 

I am looking for a solution as well. Has anyone found an alternative since the developer has seemed to abandon this?

 

Hi there,

are you still supporting the asset?
I'd need something specific as this, but looks like last update was in 2017

 

Hello there,

I bought this plugin a few months ago and made it work with Mirror instead of UNet. Hope it helps.

https://github.com/javierfoe/Multiplayer-Bluetooth-Unity

 

After testing your reposity and trying to make it work for me, I found that the Bluetooth part works nice. However, it doesn't occur the same for the Networking part. After having started the server and connected one device to it, the yellow and purple balls don't load on the screen. I mean, there might be a problem with the device browser controller.
If you've had this issue before, please tell me how you solved it

Edit: I've already purchased another high-rated Bluetooth plugin, and It works wonders. I recommend to go that path to anyone who is trying to make projects with Bluetooth connectivity.

 

if I`m right understand this plugin paided right now ?

 

Translation: "If I understand correctly, this is a paid plugin now?"

 

Hi guys,

Could please you explain me how to start working with https://github.com/javierfoe/Multiplayer-Bluetooth-Unity ?

What I've done (also tried these steps in different orders):
1. Downaloded zip archive by link above
2. Created new 2D project in Unity 2019
3. Changed build settings to Android
4. Drag and drop unzziped folder to Assets
5. Downloaded and imported "Mirror" plugin via "Assets store" tab in Unity
6. Downloaded and added https://github.com/SoftwareGuy/Igno...rance-QualityOfLife-136-20200130.unitypackage to the project (btw, it already contains Mirror folder inside!)

However, I cannot compile the project due to error:

Code (CSharp):

1. Assets\Mirror\Runtime\Transport\Ignorance\IgnoranceClassic.cs(25,37): error CS0246: The type or namespace name 'Transport' could not be found (are you missing a using directive or an assembly reference?)

My task is to make 2 Android apps. The first one broadcasts accelerometer's data in real time to the second one via Bluetooth. Please let me know if I choosed a wrong way

 

Can anybody send me (delta.cephei@outlook.com) the easiest program. Based on: https://github.com/javierfoe/Multiplayer-Bluetooth-Unity

Like: Discover function, connect function, disconnect function and a simple RPC (send a string)

Best regards
Mika

 

When I use github.com/javierfoe/Multiplayer-Bluetooth-Unity, and then add a [Command] attribute. The error occurence: Mirror: not connected. But I connected Bluetooth.

i know its hard to read but id like to know why this happens, do i need to have the target Platform set to android? what unity version do i need to open this in?
and do i need any other packages installed?

thx in advance

 

Hi mardelmariam, I recently updated the repository to the latest versions of unity and mirror. And added support for all Mirror example scenes to test the functionality. What bluetooth plugin did you purchase?
