BlueSMiRF Gold + Tcl communications

Wireless & IoT
1

Hello,

I have a BlueSMiRF Gold device that communicates with an FPGA on the wired UART side. This is paired to a USB BT dongle (D-link DBT-120) on the far side. The BT device was configred to COM2 in Windows XP Pro.

I am able to open a terminal program (DockIT or RSR232 Comm) and can receive the data trasmitted from the FPGA.

Now I want to open the same COM2 using tcl and plot the information received on a tk canvas.

However, when I execute the tcl command “open COM2” or “open COM2:” or “open COM2: RDONLY”, I get the error message:

" couldn’t open “COM2”: invalid argument".

Any suggestions/advice would be appreciated.

Thanks!
