I have written some code to transfer data from external server to Hololens. I am able to connect Hololens to the server. But I am facing problem in sending the data from server to Hololens. Whenever I call ReadData function it isn't even connected(it prints Not connected).
I am quite new to c# and unity and isn't able to sort out this matter yet.
I am using StreamSocket and DataReader classes to connect and read the data respectively. Function Connect() connects with the server in start() method and then I call ReadData function to get the data from the server. I am attaching my code file.
Can you help me out in solving my problem Thanks in advance.
