Error and connection abnormality with current SDK for windows.

[rohitgonsalves]

I have downloaded the current SDK for FR5 and tried to connect the COBOT with the SDK API Calls.
The example used from the example folders.

FRRobot robot; //实例化机器人对象
int err = robot.RPC("192.168.58.2"); //与机器人控制器建立通信连接

The err returns -2.

The I check the src from the code where in FRRobot Constructor, the sockets are already connected to 192.168.58.2
So we commented the RPC line and things work correctly.

But this should not be the case for the given examples.
Is there any good solution to that or there is a bug in the SDK?
