bluetooth lowenergy - Error code 2 in beacon transmitter for Android Beacon library -

-

i want send ble advertisement using android beacon library. below code using it.

package com.example.beacon_emitter;  import java.util.arrays;  import org.altbeacon.beacon.beacon; import org.altbeacon.beacon.beaconparser; import org.altbeacon.beacon.beacontransmitter;  import android.support.v7.app.actionbaractivity; import android.app.activity; import android.bluetooth.le.advertisecallback; import android.bluetooth.le.advertisesettings; import android.os.bundle; import android.util.log; import android.view.menu; import android.view.menuitem; import android.widget.toast;   public class mainactivity extends activity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          beacon beacon  = new beacon.builder()         .setid1("2f234454-cf6d-4a0f-adf2-f4911ba9ffa6")         .setid2("1")         .setid3("2")         .setmanufacturer(0x0118)         .settxpower(-59)         .setdatafields(arrays.aslist(new long[] {0l}))         .build();         beaconparser beaconparser = new beaconparser()         .setbeaconlayout("m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25");         beacontransmitter beacontransmitter = new beacontransmitter(getapplicationcontext(), beaconparser);          beacontransmitter.startadvertising(beacon,new advertisecallback() {             @override             public void onstartfailure(int errorcode) {                 log.e("beacon", "advertisement start failed code: "+errorcode);             }              @override             public void onstartsuccess(advertisesettings settingsineffect) {                 log.i("beacon", "advertisement start succeeded.");             }         });          int result = beacontransmitter.checktransmissionsupported(getapplicationcontext());         toast.maketext(this, "device info " + result, toast.length_long).show();      }      @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }      @override     public boolean onoptionsitemselected(menuitem item) {         // handle action bar item clicks here. action bar         // automatically handle clicks on home/up button, long         // specify parent activity in androidmanifest.xml.         int id = item.getitemid();         if (id == r.id.action_settings) {             return true;         }         return super.onoptionsitemselected(item);     } }

it gives me errorcode 2, advertise_failed_too_many_advertisers. strange thing when checked toast message says device supported beacon transmission. confused.

please help!

thanks in advance.

a few tips:

  1. the beacontransmitter.checktransmissionsupported() method checks see if device has bluetooth le , operating system give bluetoothadvertiser.

  2. to see if else has been successful getting device transmit, check see if on list: http://altbeacon.github.io/android-beacon-library/beacon-transmitter-devices.html

  3. the advertise_failed_too_many_advertisers response can indicate app advertising beacon, , advertisement slots used. make sure don't have other apps advertising in background. reboot or uninstall other apps might doing if necessary.

  4. try locate beacon app based on same library, , see if can advertise beacon successfully. eliminate possible problem code.

edit: based on comments below, reasonable conclude firmware intrynsyc eval kit not implement interface between android , bluetooth chip. otherwise either report advertising not available or not return error message when starting advertising. appropriate next step open issue intrynsyc , report these findings.
