I’m having difficulty getting this to work correctly on my Mac. I have done the above steps, can set the baud rate, and put it into Data mode. Though what’s odd is that despite whatever baud rate I set it to, I can still do AT in any other baud rate set in ZTerm.
Anyways, I then Hang-up and quit ZTerm and open the RoombaMidi. It connects, but when I try to get sensors, RoombaMidi complains “couldn’t read Roomba. Is it connected?”.
It’s an older Discovery with firmware upgraded with the scheduler upgrade kit. All the lights come on the Roomba when I plugin the RooTooth, so the firmware should be good enough as [Historic Mainstreet Inn
