|
|
* @details
|
|
|
|
The Blood Pressure Service exposes blood pressure and other data related to a noninvasive blood pressure monitor
|
|
for consumer and professional healthcare applications.
|
|
|
|
Blood Pressure Service generally makes up a profile with some other services, and it can provide the state of blood pressure.
|
|
|
|
The default supported feature provided by BLS is the indicate property of blood pressure measurement characteristic,
|
|
the read property of blood pressure feature characteristic, and the application developers can modify the feature supported
|
|
by BLS according to their own requirements.
|
|
The specific configuration process can be achieved by modifying file @ref bls_define.h.
|
|
|
|
* <b>Example usage</b>
|
|
* \code{.c}
|
|
|
|
#define BLS_INTERMEDIATE_CUFF_PRESSURE_SUPPORT 1
|
|
|
|
* \endcode
|
|
|
|
Application shall register blood pressure service when initialization through @ref bls_add_service function.
|
|
|
|
Application can set the blood pressure feature of BLS through @ref bls_set_parameter function.
|
|
|
|
Application can send the blood pressure measurement value of BLS to the client with a indication through @ref bls_blood_pressure_measurement_value_indicate function.
|
|
|
|
Application can send the intermediate cuff pressure value of BLS to the client with a notification through @ref bls_intermediate_cuff_pressure_value_notify function.
