Hey guys.

Well i have a problem, or may i say some algo that i'm not figure out. -- really geek or just idiot :D
First i'll tell the story.
I have a medical device, that record some stuff like (Blood Pressure, EKG...etc) after the measurement is finish, the device save data in his own memory.
Also have an android tablet with Bluetooth LE capabilities (Android v.7).

The main ideea is: tablet connect to medical device and download the saved data, that's all i need to do with. - and this is my problem, i cannot get the full memory ... i get a null.

On tablet i make a full app (with login + connect server + web service for auth...etc) tablet also scan a QR code and check with server.... but all this stuff i did it correctly - isn't my first app for android.

The main problem and i cannot see the solution is the full communication with a device.

I connect to device, and retrive the services and GATT characteristics... but when i

int[] data = intent.getIntArrayExtra(BluetoothLeService.EXTRA_DATA);

my data is null :))) and i cannot get the record stored in device memory.


if u have some ideea or anything :) thanks' in advanced and a BEER :)

Cheers!
