Software 2.3.0. available for BMair Connect

CONNECT version 2.3.0 supports new hardware, improves several functions and makes the controller more robust. In this service letter, you can read what has changed.

BMair CONNECT Firmware 2.3.0 release
From October 28, 2026, all newly delivered BMair CONNECT controllers contain firmware version 2.3.0. This version includes the following adjustments:

• ReCirculator (for EN 17969)
• New Protector Plus Y
• A 2nd Protector, Protector Plus X, Protector Plus Y or MAO-3C unit can be connected to 1 BMair CONNECT controller

Please note: to use (one of) these new functionalities, the controller must first be updated to firmware version 2.3.0.

Please note: a 2nd system unit has its own SKU. New PKGs with 2 systems will be released for this. The second system requires modifications, so never enter the existing SKU twice on a sales order. More information will follow in November.
Improved data handling in offline environments

• Internal data handling has been improved for systems working offline (without SIM card connection).

Improved robustness

• Robustness has been improved with regard to the 'frozen red screen' issue.

Improved buzzer timing

• The buzzer timing for the low-pressure alarm and the 'Open Door' alarm has been improved.

In addition to new introductions, our R&D department has also implemented specific changes:

• For ISO 23875 and RS 20, the low-pressure alarm threshold can now be set separately from the cabin target pressure.
