The following may help if you find yourself having problems.

  1. . Some installs of Windows XP differ in bluetooth wizards. Be aware that Windows XP Office Pro has a different wizard which defaults to COM40 for the bluetooth port.
  2. . Large COM ports may be issue for some. One student was able to use "com40", but two weren't able to. They changed it to something lower like "com8" and it worked.
  3. Make sure that the com port is given in lowercase letters.
  4. Be aware that the cable could be faulty. A faulty cable will make the Scribbler blink erratically.
  5. With lots of robots/bluetooth-devices in the room sometimes you need to search multiple times to find the one that belongs to you.
  6. forward() doesn't really go straight on a lot of robots due to differing motors.
  7. forward(x) confused some people, thinking x was time or distance rather than power/velocity.
  8. Be aware that forward(-1) makes the robots go backwards.
  9. One student used Ubuntu Linux
  10. Most bluetooth problems are solved with a laptop reboot.
  11. If students already have python 2.4 installed and then just choose "Repair" when it tries to reinstall python 2.4 and everything should work fine.
  12. If python2.5 is already installed, make sure that the other python packages (pyserial etc.) get installed correctly to the python2.4 directory.
