Remarks

Create a Bluetooth L2CAP Connection-oriented Channel (CoC) BluetoothSocket that can be used to start a secure outgoing connection to the remote device with the same dynamic protocol/service multiplexer (PSM) value. The supported Bluetooth transport is LE only.

This is designed to be used with BluetoothAdapter#listenUsingL2capChannel() for peer-peer Bluetooth applications.

Use BluetoothSocket#connect to initiate the outgoing connection.

Application using this API is responsible for obtaining PSM value from remote device.

The remote device will be authenticated and communication on this socket will be encrypted.

Use this socket if an authenticated socket link is possible. Authentication refers to the authentication of the link key to prevent person-in-the-middle type of attacks.
