We're nearing the end of our project to build a robot using the gumstix.
Using Windows XP we have set up a remote login over a virtual comm port
using Bluetooth. Using this we can log onto the gumstix and send commands to
control the robot. A program sitting on the gumstix waits for these commands
and then calls methods to manipulate our various devices. This works fine
for the I2C bus, returning data from our sensors.
The problem occurs when we attempt to send commands out on ttyS0 to a
CMUcam2. We see the commands being sent on our Bluetooth connection but they
do not seem to be going out on ttyS0. The code we are using has already been
tested on ttyS0 without the Bluetooth connection and it works fine. It
almost seems like Bluetooth is blocking ttyS0. We assumed Bluetooth was
only connected to the HWUART on ttyS3 and would not affect ttyS0.
We also assume that there is no way of using ttyS3 to send out to the
CMUcam2 as Bluetooth has to be disabled to use ttyS3.
Our buildroot is based kernel 2.6.10 and was revision 413 in the source
If anyone has any idea what is causing our problem or ways around it we
would appreciate your help.
