How is WLAN/Bluetooth chip connected to Gumstix?

I am just wondering how the Wi2Wi chip (W2CBW003) of the Gumstix Air
is connected to the OMAP processor. I am thinking about adding such a
chip to the BeagleBoard and reuse the Gumstix drivers - if possible.
Does anyone know details?

I think it is connected to the MMC interface. Not sure if it is the
same interface that is exposed on the expansion connector. You can
read the driver source and figure it out :slight_smile:

Thanks!
That illustrates the WiFi side really well. How is the Bluetooth side
of the W2CBW003 connected (UART or USB?). And, if USB - through which
port?

UART AFAIR, but I unfortunately don't remember the number...

Looping the Gumstix list and hoping for somebody to follow up :slight_smile:

UART AFAIR, but I unfortunately don't remember the number...

finally I have googled this:

http://old.nabble.com/Using-UART-2-on-an-Overo-td22534595.html

and it appears to be UART2.

Did someone confirm?

Hi Nikolaus,

and it appears to be UART2.

Nobody did confirm, but since the UART2 statement in the link you found was
made by Sakoman I would trust it 100% :slight_smile:

And I as well can confirm, that UART 1 and 3 are "officially" brought out to
the J1 and J4 Connectors, which again suggest that UART2 goes to the BT
chip...

Best regards - Good luck
