Hi, I built up the BlueSmirf interface for my Roomba. I am using a Mac to connect to the BlueSmirf, and can send AT style commands, and check the status of the BlueSmirf device. But I cannot seem to send and successful commands using Zterm to Roomba. I might not be using the right cmds, assuming you can just put the BlueSmirf in data mode. ATSW20,236,0,0,1 - set up the BlueSmirf data rate speed to 57.6K ATMD - put it in data mode 128 130 132 136 - op codes to start, control, use full mode and start cleaning This doesn't work. Anyone see what I might be doing wrong? thanks

You could try a loop around arrangement strapping Rx and Tx at the far end. Send some characters and see if you receive them on your terminal. Or, plug your Roomba charger into the charging jack and monitor the charging report that is output once per second in ASCII over the ROI.

If you're just typing the opcodes, your sending the ASCII characters, and NOT the opcodes. If you type 128, your sending the ASCII code for '1', for '2', and for '8'. You need to send a single char 128. I don't use a terminal program, so I can't tell you how to do it with your program.

We have a small tutorial on our website about using RealTerm with the Create that you might find useful. http://www.elementdirect.com/wiki/tiki-index.php?page=Windows+Terminal+Test -Ben
