I have a Roomba 871 and I am trying to communicate with it through the sci port.
I am using RealmTerm
for testing, I am trying it with the How to Program Roomba - RealTerm Terminal guide.
If I try it with a baud rate of 57600 the only thing I am able to is to get the Roomba to perform an spot cleaning. To get to that the only thing I have to do is to send it an value of 130-139, 230-239, 330-33
... But I have to send it as ASCII not as Numbers, like mentioned in the description above.
If I try it with a baud rate of 115200 the only thing I am able to do is to switch it off. But then it is switched off until I lift the Roomba up. Pushing the Power button does noting in that case. To switch it off I send the numbers like in the description above: 140 0 1 62 32
but send as numbers!
So this is quite strange and I really don't know what to do, so please help.
