You use the USB ttl chip conected to tx, rx and vcc on the bluetooth (outside of robot not connected). After you use teraterm to connect to the usbttl com port. Then you send AT commands to set your speed. Im not sure what AT commands you need so read your bluetooth instructions to see what AT command you need to send. Most times its best to copy and paste the commnd to the teraterm as typing wont work too well. ALSO some chips are already set to 115200 so read your bluetooth instructions to see what the default speed is set already.

My bluetooth does not have any lights, but gerbers does have I remember. I think if your lights flicker then probably sending tx data!
