# Usage

The Beacon demo configures a BlueNRG-1 device in advertising mode (non-connectable mode) with specific manufacturing data. It transmits advertisement packets at regular intervals which contain the following manufacturing data:

Data field | Description | Notes
Company identifier code | SIG company identifier (1) | Default is 0x0030 (STMicroelectronics)
ID | Beacon ID | Fixed value
Length | Length of the remaining payload | NA
Location UUID | Beacons UUID | It is used to distinguish specific beacons from others
Major number | Identifier for a group of beacons | It is used to group a related set of beacons
Minor number | Identifier for a single beacon | It is used to identify a single beacon
Tx Power | 2's complement of the Tx power | It is used to establish how far you are from device

- (1): SIG company identifiers are available on https://www.bluetooth.org/en-us/specification/assigned-numbers/company-identifiers
- NA : Not Applicable; NOTEs:
  - OTA Service Manager support requires to build application by enabling only ST_USE_OTA_SERVICE_MANAGER_APPLICATION=1 (preprocessor, linker) options and through files: OTA_btl.[ch] (refer to Release_with_OTA_ServiceManager IAR workspace).
