Re: problems communication protocol with external server

"servers log says that i send all zeros"

 

Have you put a break point at:

_out.write(bufhello, 0, 8); // 8 bytes to start the connection

 

and checked that bufhell contains the data you expect?

 

To test this another way, you could replace your code with

_out.write("UB00000001".getBytes()); // 8 bytes to start the connection
