Hi Marcel,

I have found an interesting article about this (for people who find this 
interesting as well !) :

http://www.us.design-reuse.com/articles/5715/adaptive-frequency-hopping-for-reduced-interference-between-bluetooth-and-wireless-lan.html

Sorry to carry on theorically speaking, but in my opinion it's always good 
to understand the underlying techniques ... do you know how AFH is 
implemented by chips ? Is the channel blacklisting "manually" up to the 
developper (software), or is there a built-in blacklisting algorithm 
(hardware) ?

Regards,
Oli
