Beta version of BLE extension for Android 12 permission changes

If you set the targetSdkVersion=29 the app (APK) will not allowed by Google (in the Play Store). The minimum targetSdkVersion has to be 31.

[Madhav]

Hi Taifun,

Thanks for letting know about this. I'm aware you have built your own extension for Bluetooth client. I believe you have enough info and means to solve the issue. Can you please help us.

that is true Anke.
I just tried the same but with targetSdkVersion="31" instead, and the bug is there again with the pop up : "need android.permission.BLUETOOTH_CONNECT .... "

[Madhav]

But if we set to 31, then app throws an error for Bluetooth permission. How do we solve the issue then?

[Anke]

Also you can no longer upload / release an APK to the Play Store as long as the app (as APK) has not already been released before August 1st, 2021.

In my bluetooth client extension I introduced a method to ask for permissions like this
in my tests this was working up to now...

Taifun

  /**
   * RequestBluetoothPermission
   */
  @SimpleFunction(description = "Request Bluetooth Permission.")
  public void RequestBluetoothPermission() {
    Log.d(LOG_TAG, "RequestBluetoothPermission");


    if (isRepl)
    {
      ErrorOccurred("You will have to build the app to be able to test this method.");
    } else if (ApiLevel()>30){
      ActivityCompat.requestPermissions(form,
          new String[] {
              "android.permission.BLUETOOTH_CONNECT",
              "android.permission.BLUETOOTH_SCAN",
              "android.permission.BLUETOOTH_ADVERTISE",
              "android.permission.ACCESS_FINE_LOCATION"
          }, BLUETOOTH_PERMISSION_REQUEST_CODE
      );
    } else {
      ActivityCompat.requestPermissions(form,
          new String[] {
              "android.permission.ACCESS_FINE_LOCATION"
          }, BLUETOOTH_PERMISSION_REQUEST_CODE
      );
    }
  }

Summary

[Madhav]

But, isn't this for the BLE and not for Classic Bluetooth??

[Ghica]

Hc-05 is classic BT indeed. But both BT versions could use some more attention.

@Madhav

But, isn't this for the BLE

I was referring to this app:

@Sudarshan_Gupta

Refer to the updated mit app:
BTReadWrite.aia (296.0 KB)

Apparently I've slowly lost track of what this is all about. No wonder after more than 120 posts.

@Madhav

for Classic Bluetooth

Try this one (on Android 12+) → Companion & APK:
BluetoothClient_perm.aia (9.8 KB)

Blocks

And post screenshots after running Companion & APK.

[Madhav]

Companion gets disconnected on its own after few seconds.
Screenshots of apk on phone as below,

@Madhav

Companion gets disconnected on its own after few seconds.

Companion should look like this:

Capturing Device Logs using adb logcat

ADB is a command-line utility that that can be used to control your device over USB from a computer. It will allow you to install / uninstall and or view logs on your device. This could be very handy when there are issues with a specific app and you like to view the logs for information that may lead to identify the cause of error. In this post, we’ll discuss how to install and use ADB. Installation: ADB comes with Android SDK. However, you can download ONLY the ADB files from HERE . Download…

Hi Anke.

seems that I have the same problem as Madhav, so I tried to run Your BluetoothClient_perm.aia

Below you can find a screenshot after running app.

Then I add a simple block to connect with my Bluetooth module HC-05 (Classic Bluetooth), shown below

When trying to connect with my HC-05 module that is available on the list with BT devices, I'm getting the same result/error as in all my application that was working a couple of weeks ago. Error shown bellow.

Is there any solution to this issue? What I'm doing wrong when trying to establish the connection (basing on .aia that you shared) ? Thank you in advance.

This appears to be a common issue with Xiaomi's Bluetooth implementation in Android 12, as it has been reported a number of times on StackOverflow (e.g., 1). We are discussing next steps to take in this regard.
