Dear All I'm trying to communicate with a BLE module through a Linux machine (the module is running a heart rate profile). So far, I've been able to do everything I need except listening for Notifications and indications. I've searched through the web, forums, and even tried walking through the source code and still could not find the answer. I'm using kernel version 3.5 and bluez-5.3. Any help is greatly appreciated as this is part of my final year project. Thanks Youssif P.S.
