Hi Kris,

I didn't use the level shifter that came with the console-vx, I used the TTL logic level that is on the BTuart header (remove the RxD resister). I am still having problem with the driver (I think it is the driver) on the BTuart, and wonder if any else have any other comments on it.

Thank You

Hi,

I'm having the same kind of problem with the ttyS1
using the verdex-bt with console-vx.  I did the patch
(to connect the gnd1 net to gnd).  My problem is that
the uart seems not to work at all while the other
serial port is working fine.  Did you configure the
pxa differently ?

thank
