With the power supply plugged in, the SCI will output in ASCII text the charging information once per second. The Roomba will not respond to any input commands during that time except the reset command "7".
Yes, I used those commands to check if the rootooth is connected to My pc. Then i tried to send "128 131 135" as numbers to tell roomba to start cleaning, but nothing happens, roomba doesn't respond with anything.
1. I removed the bluetooth device from my pc and added it again. 2. Two serial ports was assigned com3 and com6. 3. Rootooth doesn't respond when I connect to com6 but on com3 it does. 4. When I plug in the power supply I got this code displayed only once

With or without the power supply connected, roomba doesn't move or respond when I try to send any commands to it.
Getting back to basics to test your connection is difficult when using a Rootooth since it is powered by the SCI pins. If you have an alternate way to power the Rootooth and can short the T & R connections then what is sent from your terminal should loop back and be displayed on your terminal.
