I am running this fucnction in loop and sometime it gives above error and i did't get the issue behind it.
And after that error hangs up on the screen
please suggest me something to resolve above Error

You can't use bluetoothSerial.write in a loop.
Like
for (var cnt=0;cnt<=10;cnt++)
bluetoothSerial.write

Because it's a async call
So you have to use success method

1. Fill a list
2. loop through this list with onSuccess methods

Hope this helps
