Android studio BLE Max Client Reach

I am trying to read data from a BLE device 24/7. I am able to scan it and can get the data but when the device is not in the range, then it will scan every 30 seconds ( I have created a handler) and after 32 attempts the app will crash. I checked the log and I am getting the following error

can't register GATT client, Max client reached: 32
Register with GATT stack failed.

This is my code that that runs when the BLE device is disconnected

if(newstate = BluetoothProfile.STATE_DISCONNECTED) {
   if(mGatt !=null) {
     mGatt.close();
     mGatt = null;
   }
   queues.clear();
   handler.postDelayed(runnable = new Runnable(){
     public void run(){
      handler.postDelayed(runnable, delay) //3000ms delay
      BLEManager.getInstance().connectDevice(address) // device trying to reconnect 
     }
    }, delay);
   }

Any suggestions will be highly appreciated

First of all,
I'd suggest you to use RxAndroidBle or Kable for cleaner code.

Each device has a Gatt connection limit. To not reach that limit you have to close connection when you done with that Gatt object.
