Guys, any chance of a work around for getting the inbuild BT4 HW working on android 4.2.2?
Did a google search found:
Don't worry, "Minumum Android 4.3 version required!"
Two usb ports, but we can only use one is a bit
"Android's SDK doesn't have support for BLE prior to 4.3.
Third party libraries can enable BLE on Android 4.2 and lower where the device's hardware supports BLE,
such as on Samsung's S III, 4 and Note 2 and on the HTC One.
I only have experience using Samsung's SDK on 4.2 (which is now deprecated), so I can't really help you further.
I can't reiterate enough-- there is no standard BLE support on Android 4.2 and lower.
You'll need to use third party solutions on a per-device basis."
