Hello,
I’m actually using the BLE for a project.
I’m having a problem when I use the scan function.
Here is how I use it:
BLE.scan([],20).subscribe((device) =>{
this.devices.push(device);
console.log("devices:");
console.log(this.devices);
});
When I call this function I see in my console the devices, but they are not displaying in my view.
Here is how I try to display the devices, I call the scan function when I click on the button.
<ion-content padding>
<button ion-button (click)="enableBLE()" > Scan for BLE devices </button>
<ion-list>
<ion-item *ngFor="let device of devices">
<h1>{{device.id}}</h1>
</ion-item>
</ion-list>
<ion-content>
I tried using the ChangeDetectorRef with the markForCheck() function to notice angular that the value changed, but it only changed when I pressed a second time my button.
I want to display it without having to press the button a second time.
Do you know what I can do to display the devices I have or where is my problem?
Thanks !
