Thats wierd. So if you send a command that requires no reply by the roboclaw and then send another command to the other roboclaw that also requires no reply, it only works correctly if you have nearly a second delay between the sends?

Yes

Do you have any C code that has successfully worked for you simultaneously talking to two boards using packet serial?


Even tried just this... which works
Code:
echo -e "\x80\x00\x3C\x3C" > /dev/ttyUSB1


but this only turns on the first addressed board..

Code:
echo -e "\x81\x00\x3C\x3D\x80\x00\x3C\x3C" > /dev/ttyUSB1

The problem we have right now is we don't have any of the Rev A and Rev B boards to test anymore. I will grab a couple Rev C boards when I go to the warehouse and test them to make sure they will work. We'll have to swap out your green boards for the new ones.

Ok,

Thanks for the effort in helping, much appreciated!

Anxious to get an ROS package out there for it.

Sorry about the delay. I will run a test on the Rev C boards later today. I've been out of the office most of the week.
