I did not paste the code as I have already tested it. It works fine for any packet.

Except that it doesn't work, does it?

You are possibly assuming that a single write at one end will result in a single read at the other end: assuming that all the data sent is available when readyRead() is emited. Of course we have no way to know.

He is using UDP so in this particular case, as an exception to all other similar issues we're listening to, this time this is not a problem

I'm still convinced we're dealing with some const char * function somewhere.
