[Yaaic] timeout on android 2.3.3

[plumps]

hi @all,
I installed yaaic today and configured sucessful. But if I but my
adnroid to my pocket ist takes approx. 5 Minutes and then I'm off.
yaaic states still online and recognizes/ reconnectes if I try to post
something.
What to do to prevent (ping) timeout?
