Android seems drop event from bluetooth communication

I'm new in Android world, WebApp and also in bluetooth. I need to develop a web app that connect with a device that sends data at 256hz. For the bluetooth communication I use bluetooth web api released from google. I have 5 characteristics that notify me when value change and I know that the notification come in a certainly order. When my app works on a pc everything is ok but when I run my app on a android chrome browser seems that the app drop some packets. I know that android spread events on the system and every app has an event queue to recive and use that events. It is possible that app event queue can't contain so match event?
