Update Extension Ble

Hello everyone, I would like to know how I do to replace an outdated 2017 bluetooth extension with a more updated 2020 extension without losing the skits, it seems like a simple question but I'm a layman in arduino and in these app creations. any help is welcome :slight_smile:

Which skills?

Sketch is Arduino's programming part, I think you are talking about Sketch here. I dont think your Sketch is going to be affected by extention update. Why not you experiment with a copy of your AI2 project with keeping working project intact.

First, create a backup of your project, save your .aia file (always keep a copy of your old project).

Update with the new version of the BLE extension.

Export this new .aia for testing.

Open it with a decompressor, for example Winrar.
Delete the old extension.
