UM7 IMU Warning - Discarding packet due to bad checksum

edit

Good Day,

I am on ROS melodic using Ubuntu 18.04. I just purchased and calibrated a new CH Robotics UM7 IMU. I installed the ROS package and executed the command rosrun um7 um7_driver _port:=/dev/ttyUSB0 the package runs and creates output on the /imu/data topic but I get a lot of the warnings indicated below:

WARN 1658530292.666356059:Discarding packet due to bad checksum.

WARN 1658530293.666356059: Discarded 45 junk byte(s) preceeding packet.

can anyone tell me how to solve this?

Regards, Che
