Has anyone successfully been able to send BT commands to the NXT using Perl on
Windows and get a response?
I've been trying to send the Get Firmware command and have not gotten a
successful response. Here is a short script:
$data = "\x02\x00\x01\x88"; # The Get Firmware command with length 2
$| = 1; # Flush buffer after write
open( PORT, "+> :raw", COM6 ) or die "Can't open COM6: $!";
print PORT $data; # Write Get Firmware command
sleep 1; # wait a sec
$line = <PORT>; # read the response from the NXT
I've also tried the Win32::SerialPort method with no luck either.
I monitored the transfer with PortMon and see no response coming back from the
NXT. Or, strangely, I will sometimes see the first three bytes that I sent come
back.
I also monitored all of the BT ports using Portmon when I used NeXTTool to get
the firmware version. COM6 is the BT port, but I will see NeXTTool use COM14 to
setup the port, but then I see no write or read results. I guess it is bypassing
the stack that PortMon monitors.

| (...) I guess no one is using Perl to communicate with the NXT over Bluetooth. Or everyone is busy building bots. I found something that seems to work reliably on my HP Laptop running Windows 2000. It has a built-in CSR Bluetooth module that is 1.1 (...) (18 years ago, 6-Sep-06, to lugnet.robotics.nxt)
