As said in the title. I’m looking for a way to connect two mobile devices via bluetooth connection: Android to Android and IOS to IOS; Aa far as I’m aware Android to IOS bluetooth is slightly more problematic.
Additionally, I did come accross Alljoyn, but it seems that the project is quite dead. Or at least I failed to find any new information about it and the link to its unity plugin was dead.
You can only connect android devices to each other via regular bluetooth, in order to be able to connect between android and iOS, you can use Bluetooth LE, it works slower, but it allows you to transfer information between devices. My plugin can solve your problem: Bluetooth Mobile Multiplayer | Network | Unity Asset Store
P.S. the answer is for users who can get on this topic.
