5.4.2

Discovery a sensor peripheral device

In order to discover a Sensor Peripheral device, a discovery procedure has to be started

with the master library command:

– Master_DeviceDiscovery(&devDiscParam);

devDiscParam variable allows to set the discovery parameters (discovery procedure,

interval, window, …).

Refer to the master library doxygen documentation for more information about the

command and related parameters.

The found devices are returned through the Master_DeviceDiscovery_CB() master library

callback (DEVICE_DISCOVERED status).

5.4.3

Connect to discovered sensor peripheral device

Once a Sensor Peripheral device has been found, the Sensor Central device connects to it

by using the following master library command:

– Master_DeviceConnection(&connParam);

connParam variable allows to set the connection parameters (connection procedure, scan

duration, window,…).

Refer to the master library doxygen documentation for more information about the

command and related parameters.

When the connection is established with success, the Master_Connection_CB() master

library callback is called with CONNECTION_ESTABLISHED_EVT event.

5.4.4

Discovery sensor peripheral services and characteristics

Once a Sensor Peripheral device has been connected, the Sensor Central device starts

discovery all primary service procedure, by using the following master library command:

– Master_GetPrimaryServices()

Refer to the master library doxygen documentation for more information about the

command and related parameters.

When services are discovered, the Master_ServiceCharacPeerDiscovery_CB master library

callback is called with PRIMARY_SERVICE_DISCOVERY code. In particular the sensor

and environmental services are discovered.

For each discovered service, the related characteristics are discovered by using the

following master library command:

– Master_GetCharacOfService()

Refer to the master library doxygen documentation for more information about the

command and related parameters.

When the characteristics of a service are discovered, the

Master_ServiceCharacPeerDiscovery_CB master library callback is called with

GET_CHARACTERISTICS_OF_A_SERVICE code. In particular the sensor acceleration,

free fall and temperature characteristics are discovered.
