So we’re looking into getting a second BlueROV and I was wondering if getting the software to match with our current rov would be as simple as cloning the SD card from our companion and then putting it in the new one.
Ofc I would still have to update the px4 flight code through the web interface.
Otherwise, will I need to use QGC to transfer the parameters that we use, or are those also stored on the companion?
Are there any other unforeseen things I might have to change?
I would recommend just following the BlueROV2 Software Setup instructions for your #2 BlueROV2 instead of trying to copy over the SD card on the Raspberry Pi (it already comes pre-loaded with Companion) or the default parameters on the Pixhawk autopilot (pre-loaded and checked by us).
really we’re just concerned about making them both exactly the same on the software configuration side.
Most of our stuff is no longer out-of-the-box Blue Robotics, as I’ve modified the pixhawk and companion code. Additionally I’d like to preserve the current parameters and such so that i don’t have to re-enable the ping as rangefinder (this is just example) or redo whatever other small changes i made to the companion computer or flight params.
Essentially, one will be for using and the other will be for testing new modifications, and, as such, it’s in our best interests to keep them as similar as possible.
You will still need to check your motor directions, do a compass and accelerometer calibration for the new vehicle as every ROV is a little different in its offsets even if your sensors are marked “green” when you load the parameters.
I just updated to Companion 0.0.26 and now get blank box for selecting an wifi SSID. I cannot get connection to do upload / download test. Can I clone Pi SD card from another system which has Companion 0.0.20? Is there any reason to have 0.0.26?
