The Bluetooth Low Energy (BLE) plugin gives your app the ability to scan for bluetooth devices, then connect and interact with them.
$ npm install --save @ionic-native/ble
Use the plugin as you would on any other supported platform.
Under the hood, the BLE plugin relies on Bluez which has a pretty annoying tendency to cache the devices it’s seen… forever. So even if a scan reveals a certain device, it might not be around.
Also, there is as of yet no way to access the advertiser data packet, so these are empty arrays for the moment.
