How to use Rootooth with Roomba 500 series and up

The Rootooth is manufactured to work at a default baud rate of 57600 bits per second which was the baud rate of the first Roomba models that it could be used with (400 series).  All newer series (500 and up) have a default baud rate of 115200 bits per second.

So the question becomes: How can I synchronize the baud rates of both devices to make them work together?

Well, you have to go with one of two options:
1. You can raise the baud rate of the Rootooth from 57600 to 115200 bits per second.
2. You can lower the baud rate of the Roomba from 115200 to 57600 bits per second.

Both options work.  However, based on our experience developing applications for the Roomba, we recommend changing the baud rate of the robot.

All our apps include capabilities to adjust the baud rate of the Rootooth to the proper setting based on the robot model being used.
