# Firmware Update

To perform a firmware update, a valid **_gbl._** file is required. This must correspond to the hardware revision.

After a successful connection, the current version can be viewed and the necessary characteristics can be accessed via the _Device Information_ service.

Via the _Update_ button, the user is guided to the file selection on their phone. Once the file has been selected, the final dialog for performing the update appears.

_Update button currently still grayed out_

The progress bar closes automatically upon completion and returns the result.

After completion, the connection must be **manually** disconnected and re-established, which triggers the internal update on the tag.

The new version should now be visible under _Device Information_.
