In Appmethod, we include many different components. This includes visual components for user interface elements and also non-visual components for database access, accessing device sensors/services, connecting to REST services etc.
While Appmethod includes many pre-built components for fast application development, you get full platform access to any APIs you need, including those we don’t already wrap in components.
In the case of Bluetooth, we don’t have a pre-built component, but you have full access to Bluetooth in code. Click this link to download a basic example that shows you how to detect connected bluetooth devices in code on Android.
