[Gumstix-users] How do I utilise the two serial ports in a waysmall 400xm-bt

[Ronald C. <siu...@re...>]

Hi there,

I'm trying to use a waysmall 400xm-bt to act as a wireless relay between
2 sensors that will be connected to the waysmall by serial and an
external PC.

So far I've figured out how to connect my laptop and the waysmall via
bluetooth, but I'm experiencing rather frequent disconnects, surely this
is not normal? My laptop and the gumstix is only about 30cm apart.

I'm also having a real hard time trying to understand the GPIO, the
specific questions I have are:

Can I utilise both serial connectors? (I'm confused here as various wiki
docs mentions something about reserved ports etc..)

How do I know which serial connector on the basix motherboard is ttyS2,
and what tty? is the other?

Any help, advice, directions would be very much appreciated.
