Parameter check

The parameter check tool enables you to compare autopilot parameter values across multiple drones.

Parameter check

First, you need to define the parameters you want to check in the text box at the top-left corner of the dialog window, following the instructions shown below the text box.

When all parameters are defined, press Shift+Enter to push the defined parameters to the manifest (right side of the window).

Alternatively, you can add parameters to the manifest from a parameter file using the Import button at the bottom-right corner. Parameter files should contain one parameter per line. Associated values in a standard parameter file are ignored.

Do not forget to clear the manifest before pressing Import if you wish to check only those parameters that are in your parameter file.

Once you are satisfied with the manifest, press the Next step button to go to the parameter status dialog, which will try to collect the values of all parameters in the manifest from all UAVs.

Parameter check status

The batch parameter status dialog is similar to the mission upload dialog, except that there is a < button at the bottom-left corner that takes you back to the previous parameter selector dialog.

For more information about how to use this window, please read the Upload your mission to the drones section of the Start a drone show in 10 steps with Skybrush Live tutorial.

Once the parameter values have been retrieved from all UAVs, select the Results tab in the header to compare the selected parameters.

Results

This dialog shows you an overall evaluation of the parameter consistency check, and also gives you detailed results for each parameter chosen.

Click on each parameter name to open more detailed results about its value distribution across UAVs.

Fixing inconsistent parameters

If some UAVs deviate from the value used by the majority of the UAVs, you can set the deviating parameters to the majority value directly from the results:

  • Press the Fix button next to a parameter to fix only the given parameter.

  • Press the Fix all button at the top of the results to fix all inconsistent parameters at once.

The tooltip of each button shows the number of affected UAVs and the value that will be set. The buttons are disabled if there is no clear majority value for a parameter, i.e. if two or more values are equally common.

Pressing these buttons does not modify the parameters immediately. Instead, the Parameter upload dialog opens with the required parameter changes, and the upload is restricted to the affected UAVs. Review the changes there and start the upload as usual.
