Uploading parameters from a file

I have 50 identical riggs to program, can I upload the parameters from a file on my desktop to each rigg. I have been trying to do this but I’m getting a lot of read only and 31 missing parameters. Can anyone tell me how to get round this.

Parameter files are text readable. Remove the read only values from your file. The missing parameters may be the result of features that are disabled by default but enabled on your fully configured autopilot.

Determine which features must be changed from disabled to enabled. Move the associated missing parameters from this file to another. Use the first file to enable all required features, reboot, and fill in the blanks with the second file, if that makes sense.

Going off of what Yuri said - the main key here is uploading the parameter file, rebooting, and then uploading the parameter file again. Most of the missing parameters that pop up after the first load will be enabled during the reboot.

I recommend rebooting one final time after the process if you want to go into a test flight directly after loading all the parameters.

Thank you my friends, I will try it later today and let you know how I get on.

Couple of things to consider:

  1. Be aware that none of the parameters associated with calibrations should be copied between vehicles. For example COMPASS_DIA_* and INC_ACC1OFFS_* are two such params that should never be copied between vehicles.
  2. Top Tip: Best practice is to never use the “Load from file” button in mission planner. Always use the “Compare Params” button and carefully go through the params selecting which ones to copy across. This can be made easier if you do as @Yuri_Rage suggests and edit your param files to only contain the ones that should be copied between vehicles.
  3. Finally, if you want to make your operation slicker, you can embed a param set into the *.apj firmware file, so that all of the defaults change to the values you need for your aircraft. That way the params are already set once you do a clean install. Guidance on this can be found here: APJ Tools for Custom Parameter Defaults — Dev documentation
