Differences in SCI and serial of all Roomba series

[Sean87]

Hi all,

After a while I managed to write an android app for my Roomba 530. Now if I want to expand this app, I want to be sure that it will work with all roomba series. Since I don't have access to other series, can you please tell me if there is any difference in SCI commands between different series of Roomba? Eg 500, 600 etc...

What about baud rates? Roomba 530 default is 115200, are all others use the same baud rate?

Thanks.

There are two different SCI Open Interface PDF documents. One is for the Create, 110 Dirt Dog, 4XX, 4XXX Series (57,600 baud) and the other for the 500, 600, and 700 (115,200 baud) Roombas. Most of the commands are the same but there are more commands available for the later models with more features.

400 series and create use 57600 BAUD interfaces. The 400 series, 500 series, and create have different overlapping command sets, not sure about the 600 and 700 series. If you search RR or the web you can find the SCI manuals for the older bots.
