Hello Frank,

I am trying to use Rosserial over RS485 based on your solution of Update(3) but on the Python Ros client side I always get messages complaining about wrong checksum. I think this is because of incomplete sent messages because of uncomplete TX buffer reading. I just tried as well with an Arduino nano board only adjusting the name of the respective registers, the same occurs.

I am using ROS Indigo.

Do you have successful used this solution for RS485 on Rosserial?

Thank you.
