Unable to read temperature values from Testo 104-IR BT – missing dependency in iOS demo repo

[Jpvineeth]

We are developing a custom React Native application to read temperature values from the Testo 104-IR BT device.
At the moment, we are unable to receive any measurement data from the device.

We have reviewed the official documentation and also checked the sample iOS native demo code available on GitHub. However, the demo project does not build successfully because a required library/dependency appears to be missing from the repository.

What is the exact process to activate the Testo 104-IR BT and start receiving temperature values?

Is there a working sample project (iOS / Android) with all required dependencies included?

Is device activation required every time the device connects, or is it persisted?

Environment

App: React Native

Platform: iOS (Android planned)

Device: Testo 104-IR BT

Any guidance or reference implementation would be very helpful.
Thank you.

Hi,
some versions of the 104IR-BT are supporting this GATT integration
Please get in contact with your testo dealer or the testo country representation (CSO) to verify if your device is the right one or how to replace it.
Best regards,
Thomas

Thanks, Thomas @tsctesto .

I have one more clarification. If the device supports GATT integration, do we still need to perform any authentication?

Also, in that case, do we need to use the product activation key or the company name for authentication?

Really appreciate your support and prompt response on this.

I am not familiar with the GATT integration, but the document states:
To be able to use the functions, it is mandatory to have a valid key. This key is provided by Testo and is uniquely assigned to the customer.
Please get in contact with testo CSO in your country to clarify this.
