WHy EASession inputStream isn't filling fast enough!!

Hi, I need to read data from external device using Bluetooth. My college , a hardware engineer, is filling

the external device(EAAccessory) with data , he writes each time a packet of about 100 bytes to the accessory , 100 times each second, so we are talking about rate of 10,000 bytes each second. I read the data from the accessory's input stream each time I get

NSStreamEventHasBytesAvailable event from the system into my EASession input stream and I observe that I get 100,000 bytes only after about 4.5 seconds instead of 1 sec.

Now it turns out that Apple is using a heavy security check each time my friend writes data to the Bluetooth buffer. so that might cause a delay, how can I bypass this security check to get much closer to real-time rate?

P.S -my friend tried writing bigger packets but fewer times each second to get 100K rate, but there was still a series delay when I tried to read from the Blutooth buffer.

anybody got a solution???
