Hey, 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 repository. If anyone has any idea what is causing our problem or ways around it we would appreciate your help. Thanks Aodan _________________________________________________________________ Have you tried the all-new MSN Search? Test-drive it today! http://search.msn.co.uk |
