BlueNRG-1 beacon demonstration application

The BlueNRG-1 beacon demo is supported by the BlueNRG-1 development platform

(STEVAL-IDB007V1). It demonstrates how to configure a BlueNRG-1 device to advertise

specific manufacturing data and allow another BLE device to determine whether it is in

BlueNRG-1 BLE beacon device range.

6.1

BLE Beacon application setup

This section describes how to configure a BlueNRG-1 device to act as a beacon device.

6.1.1

Initialization

The BlueNRG-1 BLE stack must be correctly initialized thus:

aci_gatt_init();

aci_gap_init(GAP_PERIPHERAL_ROLE, 0, 0x08, &service_handle, &dev_name_char_handle,

&appearance_char_handle);

See the BlueNRG-1 BLE stack documentation for more information on these and following

commands.

6.1.2

Define advertising data

The BLE Beacon application advertises the following manufacturing data:

Table 5: BlueNRG-1 Beacon advertising manufacturing data

Data field

Description

Notes

Company identifier

code

SIG company identifier(1)

Default is 0x0030 (STMicroelectronics)

Beacon ID

Fixed value

Location UUID

Beacons UUID

Used to distinguish specific beacons from

others

Major number

Identifier for a group of

beacons

Used to group a related set of beacons

Minor number

Identifier for a single

beacon

Used to identify a single beacon

Tx Power

2's complement of the Tx

power

Used to establish how far you are from

device

6.1.3

Entering non-connectable mode

The BLE Beacon device uses the GAP API command to enter non-connectable mode thus:

aci_gap_set_discoverable(ADV_NONCONN_IND, 160, 160, PUBLIC_ADDR,

NO_WHITE_LIST_USE,0, NULL, 0, NULL, 0, 0);

To advertise the specific selected manufacturer data, the BLE Beacon application can use

the following GAP APIs:

/* Remove TX power level field from the advertising data: it is necessary

have enough space for the beacon manufacturing data */

aci_gap_delete_ad_type(AD_TYPE_TX_POWER_LEVEL);
