How to bypass continuous sample time not allowed?

Hello,

I have a serious problem in my simulation when I try to connect two different blocks (bluetooth and Wifi 802.11b block) but I have an error message saying continuous sample time not allowed. However I use all the time discrete sample time. I checked the sample rate in the source but I cannot see the sample rate in a certain bus, in order to match them. Could somebody help me? My matlab version is 6 (R2004).

Best regards.

Carlos.
