I am able to connect the create 2 robot to my laptop with a serial cable. I am using putty_beta terminal to run. I am not able to key in commands in the terminal. but I am able to receive information from the robot. I want to achieve two way serial connection. What can I do?
The Roomba expects binary data. When you type in the PuTTY terminal, you are sending ASCII data. For example when you type "128" into the terminal, you are actually sending 3 bytes of data: [49 50 56]. And because many commands of the OI Spec are outside the typeable ASCII range, using the terminal in this manner won't work.
