NDEF_PUSH_DISABLED (ionic 3)

kumailrlakhani · September 24, 2018, 4:51am

I am trying to share data between 2 devices using ionic NFC plugin. By using below code:

this.platform.ready().then(() => {
  console.log("platform.ready() success");
  this.nfc.share([this.ndef.textRecord('Hello world')]).then( data =>{
    console.log("Success");
  },
  err => {
    console.log("error: ", err);
  });
},
err => {
  console.log('platform.ready(): ', err);
});

After the NfcPlugin Initialized I am getting this error:
NDEF_PUSH_DISABLED
snap

Can any one guide me how to sort out this issue?

Seems like your plugin folder is corrupt + is that your first build for a real device ?

What I would do is to remove the plugins and platforms folder completly and try to build it again like that.

Remove the plugins and platforms folder
Connect your Phone
Open your Terminal in your Apps folder
Type into the Terminal ionic cordova run android

It then will ask you if you want to rebuild your platforms and plugins folder. This may take a while to build up and reinstall everything… After that the App should work on your device just fine.

If it doesn’t please provide me your ionic info and when exactly the problem occured.

Good luck

Hello,
thank you for the response. No its not my first build on real device.

I have run these commands in sequence:

ionic cordova platform rm android
ionic cordova plugin rm phonegap-nfc
adb kill-server
adb connect MY_PHONE_IP
adb devices
ionic cordova plugin add phonegap-nfc
ionic cordova run android

Again same error appearing:

Forwarding debug port
Attaching to app.
The key “viewport-fit” is not recognized and ignored.

Ionic Native: deviceready did not fire within 5000ms. This can happen when plugins are in an inconsistent state. Try removing plugins from plugins/ and reinstalling them.

}

Does the App work when you aren’t using your NFC code ?

Else we could say that you didn’t installed the plugin right.

kumailrlakhani · September 24, 2018, 11:14am

Yes app is working fine I have put an alert on button click that is working fine.

cherry · September 24, 2018, 11:23am

Okay so your plugin works fine thats great!

Try my code wich I wrote some days ago to test the NFC Plugin. I can assure you that this one is working fine.

  sendValue() {
    //Attaching the NFC Listener
    this.nfc.addNdefListener(() => {
      this.SuccessAttach();
    }, (err) => {
      this.ErrorAttach();


    }).subscribe((event) => {
      //Send the message
      let value = this.ndef.textRecord('I am going to be sent over!');
      this.nfc.share([value]);
    });
  }

  receiveValue() {
    //Attaching the NFC Listener
    this.nfc.addNdefListener(() => {
      this.SuccessAttach();
    }, (err) => {
      this.ErrorAttach();


      }).subscribe((event) => {
        let alert = this.alertCtrl.create({
          subTitle: 'RECEIVED!',
          buttons: ['Dismiss']
        });
        alert.present();
      this.receivedValue = event.tag;
    });
  }


  SuccessAttach() {
    let alert = this.alertCtrl.create({
      subTitle: 'Attached Listener',
      buttons: ['Dismiss']
    });
    alert.present();
  }
  ErrorAttach() {
    let alert = this.alertCtrl.create({
      subTitle: 'Error Attaching Listener',
      buttons: ['Dismiss']
    });
    alert.present();
  }
}

You can also try this methods wich are also working fine. (Just replace them with the methods above…)


  sendValue() {
      var value = [this.ndef.textRecord('I am going to be sent over!')];
      this.nfc.write(value);
  }


  receiveValue() {
    this.nfc.addTagDiscoveredListener(() => {
      this.SuccessAttach();
    }, (err) => {
      this.ErrorAttach();


    }).subscribe((event) => {
      let alert = this.alertCtrl.create({
        subTitle: 'RECEIVED!',
        buttons: ['Dismiss']
      });
      alert.present();
      this.receivedValue = event.tag;
    });
  }

Basicly what I am doing here is to create an NFC-Tag on the first Phone sendValue and with receiveValue I scan over it and receive my Value.

What you have todo in your HTML:
Create an ngModel to see the received value. Also buttons wich fire the methods. I think that is what you wanted in the first place.

<ion-input [(ngModel)]="receivedValue"></ion-input>

Note: This is just to test if everything is in order and works… you can do the fine tuning then.

kumailrlakhani · September 24, 2018, 11:37am

sendValue() from where i have to call this?

cherry · September 24, 2018, 11:39am

That doesn’t matter, but ONLY the first Phone has to call it. Since this Phone will be a Tag then.

The second Phone ONLY has to call receive.

kumailrlakhani · September 24, 2018, 11:43am

I have installed this app in both phone now when I am trying to share its doing nothing.

kumailrlakhani · September 24, 2018, 11:45am

I simply want to share a string. basically this string I have to passed to a nfc enabled device which is not android. Initially I am testing on 2 android device so I can check that the value I want to pass that device my android app is passing same.

cherry · September 24, 2018, 11:47am

My code I’ve provided you is working fine it must have something todo with your Page’s code. You might have something implemented wich is causing this error. OR didn’t implemented…

I can’t do much here at the momment since I have no insight of your plugins / code.

The code is doing that .

kumailrlakhani · September 24, 2018, 11:48am

can you please share any working sample code? I can download that source code can try if it works for me?

cherry · September 24, 2018, 11:53am

I did already.

HTML:


<ion-content>
    <p>User: 1</p>
    <button ion-button full (click)="sendValue()">Send Value</button>
    <br />
    <p>User: 2</p>
    <button ion-button full (click)="receiveValue()">Receive Value</button>
    <ion-input [(ngModel)]="receivedValue"></ion-input>
</ion-content>

TS:

/*Paste this string under your export class*/
  receivedValue: any;
//


sendValue() {
    //Attaching the NFC Listener
    this.nfc.addNdefListener(() => {
      this.SuccessAttach();
    }, (err) => {
      this.ErrorAttach();


    }).subscribe((event) => {
      //Send the message
      let value = this.ndef.textRecord('I am going to be sent over!');
      this.nfc.share([value]);
    });
  }*/

  receiveValue() {
    //Attaching the NFC Listener
    this.nfc.addNdefListener(() => {
      this.SuccessAttach();
    }, (err) => {
      this.ErrorAttach();


      }).subscribe((event) => {
        let alert = this.alertCtrl.create({
          subTitle: 'RECEIVED!',
          buttons: ['Dismiss']
        });
        alert.present();
      this.receivedValue = event.tag;
    });
  }


  SuccessAttach() {
    let alert = this.alertCtrl.create({
      subTitle: 'Attached Listener',
      buttons: ['Dismiss']
    });
    alert.present();
  }
  ErrorAttach() {
    let alert = this.alertCtrl.create({
      subTitle: 'Error Attaching Listener',
      buttons: ['Dismiss']
    });
    alert.present();
  }

Hi @cherry, @kumailrlakhani

I am trying to send just a string from phone 1 to phone 2… but I can’t… basically the issue is: this.nfc.addNdefListener never fire .subscribe (event).

I can receive (with receiveValue() ) data from emulating a tag by other external app (NDEF Tag Emulator), but never between sendValue() and receiveValue(), I think it’s because phone 1 never fired .subscribe.

Do you have this same issue?

All help will be welcome.
