Web Core Web Socket limited data transfer


Can someone please explain to me how to send more than 125 characters to a socket server, because that is currently my limit. I'm sending and receiving the data as strings. Might this be the problem? E.g. do I have to work with bytes instead?

One small point of notice: the same problem can be found in the Web Crypto Chat demo, which is what I based my code upon. So, my client and server are basically the same as the demo project.

Any help is more than welcome.

Kind regards.
