Update the SD card and the web server

1. First update

If you have just built your variometer, just download the latest version of the “RootSD” folder corresponding to your firmware version from the download site.

After unzipping it, copy the files contained in this folder directly to the root of your blank microSD card previously formatted in Fat16 or 32.

Then download the zip “www” (Tab “Download web files”) corresponding to your version and after having unzipped it, copy the file www.gz at the root of the microSD card.

Don’t forget to download the topographic files for your region here and copy them to the AGL folder.

Insert the card into your vario and start it. The web server will update and then restart. Your vario is ready to be configured.
