Beacon AppID and App Token to authenticate

Proximity
#1

Here is the small question … Can we Authenticate two Beacon at single time to extract values from its sensor.

#2

Yes, you should be able to simply instantiate two BeaconConnection objects and connect to two beacons at once.

#3

Can you review it… I dnt know what is wrong in it. Here What i did,

  1. inside onCreate i put EstimoteSDK.initialize(…) ,
  2. then setRangingListener
  3. after that onBeaconsDiscovered(Region region, final List list)
  4. then i check for list is empty in if condition.
  5. Inside if condition i created new object as nearestBeacon = list.get(0);.
  6. after that int a = nearestBeacon.getMajor(); if (a == 39033) { //BeaconConnection code}
    here 39033 is major value of my beacon.
    Problem is BeaconConnection Code always shows error. I will send you the file.
    Error shows

Error:(58, 38) error: no suitable constructor found for BeaconConnection(,Beacon,)
constructor BeaconConnection.BeaconConnection(Context,Beacon,ConnectionCallback) is not applicable
(argument mismatch; cannot be converted to Context)
constructor BeaconConnection.BeaconConnection(Context,String,ConnectionCallback) is not applicable
(argument mismatch; cannot be converted to Context)

This line is the problem:

connection = new BeaconConnection(this, nearestBeacon1, ...

Because this code is inside the anonymous BeaconManager.RangingListener class, this here means the anonymous class (and thus you get the “argument mismatch; cannot be converted to Context” error). It should instead mean the MainActivity class (which derives from Context), so you need to make it MainActivity.this.

(It’s a typical Java problem of accessing the outer class from the inner class. If you want to know more, here’s a StackOverflow thread about it.)

thanks for help…
I did that but i have one problem.

I just check the value inside “connection” which is “null” : connection = new BeaconConnection(this, nearestBeacon1, …

here connection is always null.

i just want to know i have to create a separate activity for BeaconConnection

i have created nearestBeacon1 as object for Beacon which contain all the details in the packet format from a beacon with specified major id (I use major value to filter the beacon).

i think i have to pass this object to another activity and initiate BeaconConnection. But i m uable to do so. Can you help me with it.
