Hi,
I am thinking of using TI cc2541 in my project. In my project I have to use 2 bluetooth modules(BLE) and these 2 should communicate among each other as well as with android phone. In classic bluetooth there were simply AT commands but here i see there are GATT profiles !! When I try to understand GATT profiles there are lot of xml files in there ! 
I would like to know
1) How to initialize bluetooth (BLE) cc2541 ?
2) How to discover and connect with other bluetooth modules ?
3) How to transmit data (reading from any sensor ) from one BLE to another BLE ?
4) How to use GATT profiles ?
Please help !! Your help would be highly appreciated.
