rosserial over 433mhz 3DR radio

edit

Hello,

I am using rosserial tru a serial cable. Recently I made a change in my setup to use a 3DR radio on both ends. I setup the radio to 115200 bauds, checked communications by other means, and then run my ros setup, and although it gives me a lot of errors, it "kind of" works. By "kind of" I mean it works intermittently. For example when using twist_teleop, you have to press and keep pressed the button, so it takes the command. the broadcasted odometry data will be only shown intermittently.

The error lines are below pasted below:

=============================================

wrong checksum for topic id and msg

Mismatched protocol version in packet: lost sync or rosserial_python is from different ros release than the rosserial client

Protocol version of client is unrecognized, expected Rev 1 (rosserial 0.5+)

Serial Port read returned short (expected 713 bytes, received 636 instead).

Serial Port read failure:

Packet Failed : Failed to read msg data

msg len is 93

Lost sync with device, restarting...

Setup publisher on odom [nav_msgs/Odometry]

Setup publisher on /tf [tf/tfMessage]

Setup publisher on odom [nav_msgs/Odometry]

Setup publisher on /tf [tf/tfMessage]

==============================================

none of those errors above happen when using a wired link. I believe it is due to the quality of the wireless link. And I am just broadcasting odometry data.

Any ideas or reccomendations how to make this kind of setup work?

Best regards, C.
