ST BLE Sensor Profile stuck on Beginner

Hi, I’m running the ST BLE Sensor app on an iPhone and when I attempt to change the profile from beginner to expert, it does not take. The result is that many options are grayed out. Am I doing something wrong? Is there a work-around? I don’t have access to an Android device.

iPhone 16-Pro iOS 26.62, APP v5.2.6, fp-sns-datalog2 v3.3.0, STEVAL-STWINBX1

Thanks, Tony

Hi ​@Crigstar ,

When you open the Change Profile tab on iOS in the v5.2.6 it automatically will show the Beginner as selected as the default option. if you choose Expert and then Firmware Developer programmer you should see the options being enabled.

 

When you try this, what options are staying grayed out?

 

Another thing you could try is to delete the app and all the data and download it again choosing Expert / Firmware Developer from the beginning. 

 

Let me know!

Ahh, so it has the Beginner box checked even though you are or may be in Expert?

I captured the options before and after setting Expert, and also deleted the app and set Expert as the initial configuration, and all three screens have the same grayed out options (attached). I did ask this in another category and it sounds as if it’s a known issue and is being worked on.

BTW, datalog2 now upgraded to 3.4.0)

Thank you.

Hi ​@Crigstar ,

Yes, currently the Beginner box is checked by default even though you are or may be in Expert when you want to change the profile.

 

The gray options that you are showing in the screenshot are correct because this options are not available in the firmware.

Can you check with ​@SimonePradolini ? She said “ the team confirmed that the issue will be solved in the next planned maintenance release  ”.

i expected that going into Expert Mode would unlock those grayed out options. Currently, Expert mode appears to do nothing.
