Could you please specify what the expected behavior is?

Just as a friendly reminder: You can only connect to a remote device (the tv box), if the other device is accepting a connection (=> has an active Bluetooth server). You can think of it like this: Every computer on a network has an IP-Adress and you can make a HTTP-GET request to it. But unless the computer has a running HTTP-Server, the request will result in a Connection-Refused Error.

Yes other device is accepting the connection as i tried with kotlin code so it is working fine and also through our mobile it is working fine but when i am trying it from this code then it is giving me the error.

Well, your exception is suggestion, that the remote client is not accepting the Bluetooth connection, which is not an error of this package.

Just to be sure, I've just run the example app and tried to connect to an android tv box and got the exact same error, because the box is not running software (an app) that would accept a connection, but rather has bluetooth enabled for accessoires (remote, headphones).

No you mis-understood this thing. What i meant is TV is connecting with other devices like my phone's bluetooth and other's mobiles but not through this package.

Again: Connecting though a system dialog is not the same as establishing a socket connection. And you haven't told me what you want to accomplish anyway...
