Thanks a lot for your answer Peter,

Sorry if my question is stupid, but do you know if there are other bluetooth 
chips used in common dongles that would support multiple connection setups 
in parallel ? This way I could to find one of them and test it ;)

I use a simple socket "connect" to perform my connections, and having a look 
at my hcidump it seems that the low level layer is retrying the connection 
by itself, without actually leaving the "connect". Not sure how this retry 
is performed though, and how to tune it ?

I will provide you with complete hcidump tomorrow morning as Marcel asked.

Best regards,
Oli
