How to use cordova-plugin-ble-peripheral in ionic 3?

A bit of an introduction here. I’ve tried the ionic native BLE, it worked and was able to scan my devices. So after that, I tried to create its counterpart, the peripheral.

I searched for it on ionic native docs and found out it wasn’t supported so I researched about using cordova plugins directly.

I found out in my plugin.xml
<clobbers target=“blePeripheral” />

I used this and declared a variable blePeripheral on top of @Component then added Platform in order to set my ble code to run only when it is ready. To check how the functions are triggered, I put toasts inside the ble methods. (I might be wrong with the implementation, putting a method inside another one).

constructor(
public navCtrl: NavController,
public platform: Platform,
private toastCtrl: ToastController
) {
this.platform.ready().then(() => {
blePeripheral.onBluetoothStateChange(this.showToastState());
blePeripheral.onWriteRequest(this.showToastWrite());
});
}

showToastState(){
let toast = this.toastCtrl.create({
message: ‘Something happened with the Bluetooth state.’,
duration: 5000,
position: ‘middle’
});

toast.present();

}
showToastWrite(){
let toast = this.toastCtrl.create({
message: ‘something tried to write’,
duration: 5000,
position: ‘bottom’
});

toast.present();

}

Then something weird happened, once the app finished loading, both methods were triggered even if there were no changes in the bluetooth state or write requests happening.

I tried other methods, like creating a service programmatically and by JSON. (I copied this from the flashlight example found inside the plugin folder)

SERVICE_UUID = ‘FF10’;

SWITCH_UUID = ‘FF11’;
DIMMER_UUID = ‘FF12’;
property = blePeripheral.properties;
permission = blePeripheral.permissions;
flashlightService = {
uuid: this.SERVICE_UUID,
characteristics: [
{
uuid: this.SWITCH_UUID,
properties: this.property.WRITE | this.property.READ,
permissions: this.permission.WRITEABLE | this.permission.READABLE,
descriptors: [
{
uuid: ‘2901’,
value: ‘Switch’
}
]
},
{
uuid: this.DIMMER_UUID,
properties: this.property.WRITE | this.property.READ,
permissions: this.permission.WRITEABLE | this.permission.READABLE,
descriptors: [
{
uuid: ‘2901’,
value: ‘Dimmer’
}
]
}
]
};

By then, I knew that this plugin just didn’t work.I might have messed up something because I couldn’t see it in my scans, even though I programmed it to create and start advertising on click of a button.

Again, my question is. How do I use this plugin correctly and start advertising? If it is not possible to do so, then I might look in to using this

which has docs on peripherals

Peripheral Life Cycle

1. initializePeripheral
2. addService
3. startAdvertising
4. Listen for events on initializePeripheral callback
5. Respond to events using respond or notify
6. stopAdvertising
7. removeService / removeAllServices

Thank you for taking your time in reading this question and have a good day!

I hope they support this on ionic native
