In order to provide a usage example for cordova-plugin-serialusb, we provide both the Android Cordova application and Arduino sketch for the TestSerialUSB application.
This code is tested with Cordova Android 9.1.0 and Arduino IDE 1.8.16
For Cordova application run Cordova\TestSerialUSB\scripts\win10\installApp.cmd and then from same folder run
emulateApp.cmd or runApp.cmd.
You can then compile and upload Arduino\TestSerialUSB\TestSerialUSB\TestSerialUSB.ino sketch to the board and connect it to an Android device with the installed TestSerialUSB application.
Connect Android device and Arduino board using USB OTG cable.
Open the Android TestSerialUSB application on the device and grant permissions (screen similar to the following) after that you will be able to see that the Android device sends and receives messages over USB.
