5.4.5

Enable sensor peripheral acceleration and free fall notifications

Once the Sensor Peripheral device sensor acceleration and free fall characteristics have

been discovered, the Sensor Central device can enable the related characteristics

notification by using the following master library command:

– Master_NotifIndic_Status(masterContext.connHandle, handle, TRUE, FALSE);

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

command and related parameters.

When a characteristic notification is enabled, the Master_PeerDataExchange_CB() master

library callback is called with NOTIFICATION_INDICATION_CHANGE_STATUS code. On a

Sensor Central device context, the sensor acceleration and free fall characteristics

notifications coming from the Sensor Peripheral device are received through the

Master_PeerDataExchange_CB() master library callback,

NOTIFICATION_DATA_RECEIVED code. Each received values is displayed on the

connected hyper terminal (115200, 8, N, 1).

5.4.6

Read the sensor peripheral temperature sensor characteristic

Once the Sensor Peripheral device sensor temperature characteristic is discovered, the

Sensor Central device can read the related characteristic value by using the following

master library command:

– Master_Read_Value()

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

command and related parameters.

The characteristic value is received though the Master_PeerDataExchange_CB() master

library callback, READ_VALUE_STATUS code. Each received value is also displayed on

the connected hyper terminal (115200, 8, N, 1).
