Design an application using BlueNRG, BlueNRG-MS ACI APIs

In the context of the sensor profile demo, follow a simple pseudo code the GAP Central

application should use in order to configure the free fall and the acceleration characteristics

client descriptors configuration for notification:

tBleStatus ret;

uint16_t handle_value;

#ifdef BLUENRG_MS

handle_value = 0x000F;

#else /*

handle_value = 0x0013;

#endif

/* Enable the free fall characteristic client descriptor configuration for

ret = aci_gatt_write_charac_descriptor(conn_handle,

handle_value /* handle for free fall

client descriptor

configuration */

0x02, /* attribute value

length */

0x0001, /* attribute value:

1 for notification */

);

if (ret != BLE_STATUS_SUCCESS) PRINTF("Failure.\n")}

#ifdef BLUENRG_MS

handle_value = 0x0012;

#else /*

handle_value = 0x0016;

aci_gatt_write_charac_descriptor()

It start the procedure to write a

characteristic descriptor.

GATT client

aci_gatt_confirm_indication()

It confirms an indication. This command

has to be sent when the application

receives the event

EVT_BLUE_GATT_INDICATION on the

reception of a characteristic indication.
