Hi Patryk,

i see the problems and I will change it. I now made some tests and i found
out that the library waits for a specific time until it sends the signal. I
suppose that in this time it tries to repair the connection.

Is it possible to manage this time period with compiling flags or something?

Thanks,
Reto
