BluetoothLE1 extension: a permission issue

[Alfredo_Sanz]

Hello. I've made an app for counting how many pools I swimm. My app scans BLE devices, search my smartwatch and then counts how many times "appears and dissapears" form the BLE.DeviceList.
It works fine but now I need the apk version to be installed and use in my mobile. So I generate the apk from my program but...
The problem is wen I run the apk in my phone, a meesage appears warning an runtime error. I share a screenshot. My mobile is a Samsung Galaxy M12 with Android v13.
Any help will be great.
Thank you ver much in advance.

My app scans BLE devices

BLE extension - Date Built: 2023-02-23 - permissions & connecting issuses on Android 12+

Quite a few users are currently having problems with the (new) BLE extension. Here is a test app. Test it on your devices and post screenshots before and after scanning and connecting. Location permission is requested automatically (so disable it before testing). [grafik] [grafik] EDIT: See also here:

Thanks to @Anke for the original code.

This affects Bluetooth Classic and not BLE. With the latest BLE Extension (02/23/2023), the BT permissions are requested automatically, in contrast to BT Classic. However, the location sensor permission is not requested automatically, but must be done manually.

Thank you for your answer. Could you tell me where I can find BLE Extension (02/23/2023)?
Regards,
Alfredo

Beta version of BLE extension for Android 12 permission changes

Hello everyone, We have a beta version of the BLE extension that incorporates the new Bluetooth permissions introduced in Android 12. Please make a backup of your projects before upgrading the extension. Because this is a work in progress, there may be issues that still need to be addressed. If you try it out, please leave feedback in this thread. edu.mit.appinventor.ble-20230223-beta.aix (200.0 KB) Regards, Evan W. Patton, Ph.D. Lead Software Engineer, MIT App Inventor

I followed this: https://iot.appinventor.mit.edu/assets/howtos/MIT_App_Inventor_Basic_Connection.pdf
and I am pretty sure I used the latest version of the BluetoothLE extension, but still had 'permission' problems when I built and installed my apk. (but no problems when using the AI Companion)
My solution (which DOES work for me) was to

1. add a Bluetooth Client (from Connectivity) to the AppInventor Designer
2. add a Location Sensor (from Sensors) to the AppInventor Designer
3. after installing, on my phone I went into settings-apps, selected the installed app, and then added permissions for notifications (probably unnecessary), Location (and selected 'precise location'), and lastly nearby devices.
   This is ALL I did. No additional blocks were necessary
   When I run the app, it does give a popup the very first time, but I agree to permissions and...
   Now it works. Let me know if this helps anyone!

@rdubard

I used the latest version of the BluetoothLE extension

No.

Did you really read any of the links I posted?

[rdubard]

Fair enough--I did not use the beta.
I do appreciate your work on this.
I just used the one here:MIT App Inventor Extensions because I thought it would be the latest proven stable version.
No disrespect intended.

Also, I think that all those "beta" versions that have been released over the last few years should eventually become a stable version, and the link to the current extension should be in the official ai2 docs.
