Q2687 vs Q2686


#1

Hi all,

I developed almost my whole application using the Q2686, but now I need to switch to an Q2687 since the Q2686 doesn’t support the use of the parallel bus. But when I insert the Q2687 I can’t seem to connect to it and power used by the module is about 400 mA which doesn’t seems to be correct and with the Q2686 the power used by the module is about 100 mA. So my question I would like to ask is, what other differences are there between the two modules that can cause this behavior? I can update the firmware on the Q2686 using DWLwin but with the Q2687 DWLwin stops at the end of “installing downloader into wireless CPU’s memory”. Any help will be appreciated.

Thanks
