I added an array of power sensors to monitor the various devices I have added to the robot as part of a “performance per watt” exercise. The sensor array is monitored by a separate Raspberry Pi which is attached to the Ubiquity Pi via ROS_MASTER_URI, etc. environment variables.
The .msg file works great when I do rostopic echo /power_consumption from the NEW pi. But the Ubiquity pi doesn’t recognize the message format so I cannot collect the message data from other devices (analytics workstation).
Where should I put the custom .msg file so the magni will find it and recognize it? I’ve tried a lot of directories already containing .msg files, but it doesn’t seem to recognize my .msg file.
Message text: ERROR: Cannot load message class for [ina260/power_msgs]. Are your messages built?
