[ros-users] [Discourse.ros.org] Mismatched protocol version in packet: lost sync or rosserial_python is from different ros release than the rosserial client

[Gaurav Pathak]

Hi,
I also got the same error, in my case it was the simple mistake of reading from a wrong serial port. I had two usb serial connections for two sensors and their hardware device formation on ubuntu tty/ACM* got interchanged. Just changing the devices worked for me.
