For some users of Bluetooth it is often to confusion between the normal (Classic Bluetooth) and Bluetooth smart. But these are 2 different transmission technologies under the name of Bluetooth 4.0. The Classic Bluetooth you have to set like a Head set and pairing first so that it can then work with the mobile device. This means you will scan the device and couples this to the mobile device.
With Bluetooth smart a device cannot scan and pair. You need an app for that, the device supports. In the app you can locate the device then and tie. Please be careful to ensure that the Bluetooth is turned on the mobile device.
We have also learned that, so Bluetooth works with Android smart users properly with the Lollipop app version, the GPS needs to be turned on.
