Clarification on BLE GATT Access and Licensing for Testo Smart Probes (405i, 557s, 115i, 549i, 605i)

[scleravdms]

We have recently purchased multiple Testo Smart Probes, including:

1. Testo 405i
2. Testo 557s
3. Testo 115i
4. Testo 549i
5. Testo 605i

Our goal is to integrate these devices with our custom mobile application and receive live sensor data via Bluetooth Low Energy (BLE), without relying on the official Testo Smart App.

What we are trying to achieve

• Direct BLE communication with the devices
• Access to real-time measurement data
• Integration into our own workflow/system

Do these devices expose a BLE GATT server that allows access to live sensor data?

• Based on the documentation here:

it appears that:

• A license key is required
• Access to the custom service (value) is restricted
• Could you confirm if this applies to the above Smart Probes as well?

Is it possible to obtain:

• GATT service/characteristic specifications
• Required licensing for integration

If this is not publicly available, should we:

• Contact Testo support directly for access?
• Or is there an official SDK/API program for developers?
