App crashed after call bluetoothSerial.connect()

[LeDong95]

I tested with 2 phone, both have Android 13 Before (like a few weeks ago), the app i built run normal. But in past week, the app i build can't call bluetoothSerial.connect() function in my phone anymore. It can call bluetoothSerial.list() function to get list of bonded device, but when i try to test, app crash instant, no error was show. I tried to put console log in each step in my code (after subscribe to bluetoothSerial.connect() function) to debug , but nothing show in console

Can anyone help me find where the issue is please?

You need to target API 30. If you target 31 or higher this plugin will not work.

My friend phone using android 11, he can use app normal If i target api 30, i can't publish app to google store, it require api >= 31, that why i target api 33

I forked the repot because the master fork has a lot of problem. You can try to use https://github.com/giuseppelanzi/BluetoothSerial or one the other forks that you'll find in the recent issues (especially https://github.com/don/BluetoothSerial/issues/454).

Hope it helps.

Thanks for your help. I don't know what happen, but here is how i fixed it: I change some dependence version in package.json file Old package.json "dependencies": { "@angular/common": "^15.2.3", "@angular/core": "^15.2.3", "@angular/forms": "^15.2.3", "@angular/localize": "^15.2.3", "@angular/platform-browser": "^15.2.3", "@angular/platform-browser-dynamic": "^15.2.3", "@angular/router": "^15.2.3", "@capacitor/core": "4.5.0", "@capacitor/keyboard": "4.1.0", "@capacitor/status-bar": "4.1.0", "@ionic/angular": "^6.5.2", "@ionic/cordova-builders": "^7.0.0", "rxjs": "^6.6.0", ... }, "devDependencies": { "@angular-devkit/build-angular": "^15.2.4", "@angular-eslint/builder": "^14.0.0", "@angular-eslint/eslint-plugin": "^14.0.0", "@angular-eslint/eslint-plugin-template": "^14.0.0", "@angular-eslint/template-parser": "^14.0.0", "@angular/cli": "^15.2.4", "@angular/compiler": "^15.2.3", "@angular/compiler-cli": "^15.2.3", "@angular/language-service": "^15.2.3", "cordova-plugin-ionic-webview": "^4.0.0", "karma": "^6.4.1", "karma-jasmine": "~3.3.0", "karma-jasmine-html-reporter": "^1.5.0", ... }

New package.json "dependencies": { "@angular/common": "^15.0.0", "@angular/core": "^15.0.0", "@angular/forms": "^15.0.0", "@angular/localize": "^15.0.0", "@angular/platform-browser": "^15.0.0", "@angular/platform-browser-dynamic": "^15.0.0", "@angular/router": "^15.0.0", "@capacitor/core": "4.7.1", "@capacitor/keyboard": "4.1.1", "@capacitor/status-bar": "4.1.1", "@ionic/angular": "~6.6.3", "@ionic/cordova-builders": "^8.0.0", "rxjs": "^6.5.3", ... }, "devDependencies": { "@angular-devkit/build-angular": "^15.0.0", "@angular-eslint/builder": "^15.0.0", "@angular-eslint/eslint-plugin": "^15.0.0", "@angular-eslint/eslint-plugin-template": "^15.0.0", "@angular-eslint/schematics": "^15.0.0", "@angular-eslint/template-parser": "^15.0.0", "@angular/cli": "^15.0.0", "@angular/compiler": "^15.0.0", "@angular/compiler-cli": "^15.0.0", "@angular/language-service": "^15.0.0", "cordova-plugin-ionic-webview": "^5.0.0", "karma": "~6.4.0", "karma-jasmine": "~5.1.0", "karma-jasmine-html-reporter": "~2.0.0", ... }

I don't know why it fixed, but after change package.json file like this and build app. My app working normal again (The reason i change like that is i create a new app with ionic command, add Bluetooth Serial plugin, change some sample code i found online, build app. This new app worked in my phone, so i change some dependence in my app to similar to this new app)
