I just got a bluetooth module JY-MCU.
I have connected it to my arduino and it works fine, I can connect using a terminal program such as putty, or android blueterm.
Connecting it to my windows 7, the device has been added and two serial ports have been installed (19 and 20).
Only COM19 works, and is the one that I used for my tests.
Now I would like to use the arduino IDE (1.0.6) to for serial monitor and upload sketches.
Unfortunately going under Tools > Serial Port, I can see only COM20 while 19 is not present. I tried to plug/unplug, re-install, uninstall, restart, reboot... nothing..
Do you have any idea why the arduino IDE does not see the right port?
