Bluetooth Serial Permissions Issue on Android 12

[bevinGithub]

I need assistance with the Bluetooth Serial plugin, when l check for bluetooth.isEnable it returns Ok or is Disabled which is correct. If l try to use any other functions for example List or discoverUnpaired l get the error below ERROR "Need android.permission.BLUETOOTH_SCAN permission for AttributionSource { uid = 10467, packageName = com.fire.service.app, attributionTag = null, token = android.os.BinderProxy@a208f16, next = null }: Starting discovery."

Your assistance will be much appreciated.

Below is my environment Ionic: Ionic CLI : 6.20.1 Ionic Framework : @ionic/angular 6.2.2 @angular-devkit/build-angular : 13.0.4 @angular-devkit/schematics : 13.0.4 @angular/cli : 13.0.4 @ionic/angular-toolkit : 5.0.3

Cordova: Cordova CLI : 11.0.0 Cordova Platforms : android 10.1.2 Cordova Plugins : cordova-plugin-ionic-keyboard 2.2.0, cordova-plugin-ionic-webview 5.0.0, (and 14 other plugins)

Hi!

We have managed to have this plugin working on Android 12, etc...

The solution is yet not well tested but you might find it usefull.

Remember to add these permissions on your app's AndroidManifest.xml

  <!--BLUETOOTH PERMISSION-->
  <uses-permission android:name="android.permission.BLUETOOTH" tools:replace="android:maxSdkVersion" android:maxSdkVersion="30" />
  <!-- Needed only if your app looks for Bluetooth devices. If your app doesn't use Bluetooth scan results to derive physical location information, you can strongly assert that your app doesn't derive physical location. -->
  <uses-permission android:name="android.permission.BLUETOOTH_SCAN"
       android:usesPermissionFlags="neverForLocation"
       tools:targetApi="s" />
  <!-- Needed only if your app communicates with already-paired Bluetooth devices. -->
  <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
  <!-- Needed only if your app uses Bluetooth scan results to derive physical location. -->
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

I change the AndroidManifest.xml with this suggestions, but tags tools:replace="android:maxSdkVersion" and tools:targetApi="s", doesnt find in my project, after removing this tags my project starting in debug mode, but when you start bluetooth the error appears I/ViewRootImpl@1a9ba7c[MainActivity]: stopped(false) old=false D/CordovaActivity: Resumed the activity.

awesome this is working!!!.. i have searched all cordova bluetooth library and tried it..but no luck.. thank you very much @brandomcombr

[giuseppelanzi]

Coincidentally i was doing a very similar thing of @brandomcombr, in my fork https://github.com/giuseppelanzi/BluetoothSerial.

I'm posting this message only because I added something. I don't like the fact that the plugin is always asking for fine location permission. That should be used if I need to determine the physical position of the device, which I don't. So I added the boolean parameter fineLocation to discoverUnpairedDevices.

Hope it helps if someone is struggling for a similar reason.

How did you implement this on your project? I am still facing the challenge. I even replaced the package with (https://github.com/brandomcombr/BluetoothSerial/pull/1) still doesn't work

I am using cordova. I just change the git url in package.json In my capacitor project I use the original plugin. No problem at all.

[lajith111]

Some one please share package.json for change project url to https://github.com/brandomcombr/BluetoothSerial/pull/1

so that i canuse in adroid 13

EDIT:package.json current

 "@awesome-cordova-plugins/bluetooth-serial": "^6.6.0",
 "cordova-plugin-bluetooth-serial": "^0.4.7",

[emilkitua]
