Hi,  I am trying to create hybrid application to scan nearby bluetooth devices. For that i have generated apk using phonegap build. I have already added bluetoothSerial plugins in the config file of phonegap build. But the problem is when i try to execute javascript action i am getting this following error ERROR :  bluetoothSerial is not defined ReferenceError: bluetoothSerial is not defined Please leave some comments/ideas about this issue. <?xml version="1.0" encoding="UTF-8" ?> <widget xmlns = "http://www.w3.org/ns/widgets" xmlns:gap = "http://phonegap.com/ns/1.0" id = "io.mxapps.bluetoothsample-sandbox" version = "0.0.32" xmlns:android="http://schemas.android.com/apk/res/android"> <name>Bluetooth-Sample</name> <description>Testing for scanning the bluetooth devices</description> <!-- Current latest and default version Platform versions don't follow a common version number anymore (see: http://phonegap.com/blog/2015/06/16/phonegap-updated-on-build/).
