     - Wi-Fi is shown in yellow while connecting and green when connected.
  - General stability and reliability improvements.

• Firmware V20 (2.20) ->
   - Improved test selection across the three measurement chambers:
      - Tests that are unavailable in the current chamber remain visible but are clearly grayed out.
      - On-screen guidance shows when a test is available in another chamber.
   - Enlarged and highlighted chamber guidance for easier navigation.
   - Improved spacing, alignment, and color consistency of the header icons.
   - General usability and stability improvements.

2023/06/27

Firmware Changes:

• Implemented Bluetooth functionality for updating the database.

2023/06/13

Firmware Changes:

• Fixed database recovery mode for interrupted database update.
• added additional parameters to the „check for updates“ routine.
• minor button state changes (e.g. being able to enable Bluetooth while the device shows the image „connect device to app“).
• added optimized Bluetooth commands for database updates via Bluetooth.
• optimized production test for next mass production.

Synchronization Server Application Changes:

• only deliver database updates to firmware version 4 or higher.
• if a device hasn’t mapped any of the cloud account sampling points, all sampling points (max. 20) will be mapped to the device automatically on first synchronization.
• to avoid uploaded measurements without a mapped sampling point, measurements that are uploaded with the „Default Source“ sampling point, will be added either to the first mapped sampling point of the device or to the first sampling point of the cloud account.

2023/05/26

Firmware Changes:

• Fixed a bug that caused some devices to be unable to shut down properly, resulting in battery drain over night.
• Resolved an issue where a few devices did not save their serial numbers during production.
  Note: If your device was connected to the cloud without a serial number, please reconnect it to the cloud via the app.
• Fixed a bug that failed to save the state of a disabled parameter from the last selected parameter entries (T1, T2, T3).
• Improved the speed of BLE updates through the app.
  Note: requires new LabCom app release.
