/* Main Application Loop */

{

Process any pending HCI events read */

HCI_Process()

/* User specific application function where user actions and events are

processed (advertising, connections, services and

characteristics

discovery, notification)

User_Process();

}

} /* end main() */

Note:

1. User_Process() is just an application dependent function. On the following sections,

some reference specific actions/events are described based on the most common BLE

functionalities. User developer can adapt/modify/replace them.

2. When performing the GATT_Init() & GAP_Init() APIs, BlueNRG and BlueNRG-MS stacks

always add two standard services: Attribute Profile Service (0x1801) with Service Changed

Characteristic and GAP Service (0x1800) with Device Name and Appearance

characteristics.

3. The last attribute handle reserved for the standard GAP service is 0x000F on BlueNRG

stack and 0x000B on BlueNRG-MS stack.

4. The GAP_Init() role parameter values are as follow:

Further, on BlueNRG-MS stack, two new parameters are available on GAP_Init() API:

–

enable_Privacy: 0x00 for disabling privacy; 0x01 for enabling privacy;

–

device_name_char_len: it allows to indicate the length of the device name

characteristic.

For a complete description of this API and related parameters refer to the UM1755

and UM1865 User Manuals, on the Section 4: References.

Role parameter values

Note

BlueNRG

0x01:Peripheral

0x03: Central

Broadcaster, Observer are not

supported on BlueNRG device

BlueNRG-MS

0x01:Peripheral

0x02: Broadcaster

0x04: Central

The role parameter can be a

bitwise OR of any of the

supported values (multiple roles

simultaneously support)
