IOS not working about simple_beacons_flutter HOT 16 OPEN

Is working for you on android ? I'm trying and doesn't works for android or ios. If working for your on Android please help me or send me you code.. I'm trying many days now to figure out..

Thank you!

from simple_beacons_flutter.

The example in the README is wrong. Use the example from the project itself

from simple_beacons_flutter.

Also project doesn't work... I'm looking so many days how to create an app that can scan beacons nearby and doing something, like notification.

from simple_beacons_flutter.

It is working for me... maybe your beacon?

from simple_beacons_flutter.

This example working and detect to beacons ? Hmmm my beacon is from a company blueup and from configuration app's company works well.

Can you help me to fix it and show if it works ?
Thank you.

This is the code I am using:

    if (GetPlatform.isAndroid) {
      await BeaconsPlugin.setDisclosureDialogMessage(
          title: "Need Location Permission",
          message: "This app collects location data to work with beacons.");
    }

    BeaconsPlugin.listenToBeacons(beaconEventsController);

    BeaconsPlugin.setDebugLevel(2);
    await BeaconsPlugin.addRegion("myBeacon", uuid);

    beaconEventsController.stream.listen(
        (data) {
          if (data.isNotEmpty) {
            print("Beacons DataReceived: " + data);
          }
        },
        onDone: () {},
        onError: (error) {
          print("Error: $error");
        });

    await BeaconsPlugin.runInBackground(true);
    await BeaconsPlugin.startMonitoring;

    if (GetPlatform.isAndroid) {
      BeaconsPlugin.channel.setMethodCallHandler((call) async {
        await BeaconsPlugin.startMonitoring;
        if (call.method == 'scannerReady') {
          await BeaconsPlugin.startMonitoring;
        }
      });
    }
  }

@leobispo In the addRegion the first option "myBeacon" is option and you can write what ever you want. The second is the proximityUUID?

from simple_beacons_flutter.

@leobispo I tried also your code but not working for me .. Can you help me more please ? How I can do this working ? I have spent a lot of time and I have nothing since then.

Very nice, can you send me a link weTransfer with your code, to my email ([email protected]) please?

Thank you!

from simple_beacons_flutter.

@peterpoll you need to specify the region correctly, uuid is case-sensitive

from simple_beacons_flutter.

by the way, the implementation for android does not react at all to the scanned region, and in iOS you need to specify the region, otherwise the scan result will be ignored. in my case, I even had to change the uuid of the beacon

Are you able to create a mini prototype of your working version? I have now spent a few days investigating why my iBeacon is not displaying on iOS.

I have setup the beacons UUID (iBeacon) and configured the code to match (also case sensitive as you've suggested). Project swift file and plist has been updated per example. Working fine on Android but absolutely no response on iOS. The location permission in settings is set to 'Always@ and there are no errors in debug.

Using BeaconSet+ app i can see the beacon straight away on the device.

I am out of ideas with this package at this point.

from simple_beacons_flutter.

So I just got this (kinda) working.. it seems that as soon as I add in more than one region to scan, iOS doesnt detect any!

This fails..
await BeaconsPlugin.addRegion("MyBeacon", "696e6974-7379-7300-0000-0070616e6963");
await BeaconsPlugin.addRegion("MyBeacon", "696e6974-7379-7300-0000-000000000001");

whereas this works and detects the first beacon..
await BeaconsPlugin.addRegion("MyBeacon", "696e6974-7379-7300-0000-0070616e6963");
//await BeaconsPlugin.addRegion("MyBeacon", "696e6974-7379-7300-0000-000000000001"); <-- commented out

Ideally I need to be able to scan for several regions (note the last 12 chars are different) as configuring the major/minor creates us an limitation that is not ideal to our use case.

Has anyone got this working where multiple regions work?

from simple_beacons_flutter.

Hello,

you put uuid in region and in ibeacon config?

i can find with android, but with iOS I can’t see any beacon. And I don’t have any error.

Any suggestion?

from simple_beacons_flutter.

Can you search beacon on ios?
