Android Question Bluetooth BLE Difference between Android 7.1.1 vs 10.0??

I've got a customer in the field who has Android 10.

His Bluetooth is turned on and he can access BLE devices via apps. On each app screen at the very top his Bluetooth icon is displayed...

...except on mine!

I've got 2 Android phones, one running 7.1.1 and the other running 9.

On those 2 test phones I clearly see the Bluetooth icon displayed on the upper status bar as shown here:

Anyway, my test phones use my app just fine. It's a remote control that moves your TV left & right mechanically. His Android 10 phone, however, shows that bluetooth icon on every app except for mine.

So my customer in the field gets no Bluetooth signal from my app to my control circuit.

He's running Android 10 and I'd love to know if I need to do something different to get my Bluetooth (BLE) remote control working on his phone.

Has anyone seen anything different on Android 10 for Bluetooth??

Have I not asked for the correct Permissions on the Google Play Store?

Ok, thanks. Anything else that I should ask him upfront? I'd prefer to not keep coming back to him for multiple question sessions, if possible (you know, customer and all that).

I've got "Location" turned off on my 2 test phones, but Bluetooth is working just fine if that matters.

your 2 tests phones are using Android 10? If I understand correct you don't have Android 10 in any phone to test.

Edit:

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...

Edit2: if you like I can test your App here
Edit3: You can update from v9 to v10 your Smartphone

Yes, please.

It is "TVtilter" on the Google Play store. If Bluetooth is running on your phone and you approve Location access on the very first Open, then I'd love to know if you see the Bluetooth icon on your upper status bar.

The rest of the app is hidden until you connect with my hardware, so you won't see much of an app screen since you don't have that hardware, but that's not needed to see the initial scan/test of the upper Bluetooth icon at Opening.

My 2 test phone are Android 7.1.1 and 9.0, but I may take your suggestion and upgrade the 9 to 10.

BLE works up to android 11. Be sure you got fine location is ON in your CODE. Follow Erels example of BLE.
I know BLE also works on android 10. Got a app with BLE so i'm pretty sure.

then you need to test your App in Android 10 to confirm what is going on

Why would the Android 10 OS not display the Bluetooth icon on the status bar when my app is pulled up?

Customer sees that bluetooth icon in the upper status bar when he loads other bluetooth apps.
I see that bluetooth icon when I run my app on Android 7.1.1 and 9.

Seems unusual that this could be a code problem.

I'm thinking permissions or OS issue.

That is why you need to debug using an Android 10 to make sure everything work as expected.

Customer has a Samsung Galaxy 9.

Unless you know a secret, Google Play Store won't allow an APK to be uploaded to the store that targets anything older than SDK 29.
