iBeacon#
1. Purpose / Scope#
This application demonstrates how to set the iBeacon data format in advertising parameters in BLE peripheral mode.
2. Prerequisites / Setup Requirements#
Before running the application, the user will need the following things to setup.
2.1 Hardware Requirements#
Windows PC with Host interface(UART/ SPI/ SDIO).
Silicon Labs RS9116 Wi-Fi Evaluation Kit
Host MCU Eval Kit. This example has been tested with:
Silicon Labs WSTK + EFR32MG21
Silicon Labs WSTK + EFM32GG11
Smart phone with ibeacon detector application
2.2 Software Requirements#
Embedded Development Environment
For STM32, use licensed Keil IDE
For Silicon Labs EFx32, use the latest version of Simplicity Studio
Download and install the iBeaconDetector app in the android smart phones for testing BLE applications. Users can also use their choice of BLE apps available in Android/iOS smart phones.
iBeacon Advertise Data Format
iBeacon prefix UUID Major Number Minor Number TX Power 9Bytes 16bytes 2Bytes 2 Bytes 1bytes
Adv Flags Adv Header Company ID iBeacon Type iBeacon Length 3 Bytes 2 Bytes 2 Bytes 1Byte 1Bytes
iBeacon Prefix: Vendor specific fixed value. Default iBeacon prefix values setting by application is, Prefix = {0x02, 0x01, 0x02, 0x1A, 0xFF, 0x4C, 0x00, 0x02, 0x15}
UUID: User generated proximity UUID. Remote devices recognize which beacon they approach on the basis of UUID, major and minor numbers. Default UUID, Major and Minor values setting by application is, UUID = {0xFB , 0x0B , 0x57 , 0xA2 , 0x82 , 0x28 , 0x44 , 0xCD , 0x91 , 0x3A , 0x94 , 0xA1 , 0x22 , 0xBA , 0x12 , 0x06} major_num = {0x11, 0x22} minor_num = {0x33, 0x44}
TX Power is used to calculate distance from iBeacon. Default TX power value setting by application is, TX Power = 0x33
Note: If the user wants to change the prefix, UUID, Major number, Minor number and TX Power values, change the following values in rsi_ble_ibeacon.c_ file.
For Prefix:
<span style="color: #005032">uint8_t</span> adv[31] = {0x02, 0x01, 0x02, 0x1A, 0xFF, 0x4C, 0x00, 0x02, 0x15}; //prefix(9bytes)
For UUID:
uint8_t uuid[16] = {0xFB , 0x0B , 0x57 , 0xA2 , 0x82 , 0x28 , 0x44 , 0xCD , 0x91 , 0x3A , 0x94 , 0xA1 , 0x22 , 0xBA , 0x12 , 0x06}; For Major Number: uint8_t major_num[2] = {0x11, 0x22}; For Major Number: uint8_t minor_num[2] = {0x33, 0x44}; For TX Power: uint8_t tx_power = 0x33;

Refer STM32 Getting Started
Open the project
<SDK>/examples/snippetsble/ble/ble_ibeacon/projects/ibeacon-nucleo-f411re.uvprojxin Keil IDE.Build and Debug the project
Check for the RESET pin:
If RESET pin is connected from STM32 to RS9116W EVK, then user need not press the RESET button on RS9116W EVK before free run.
If RESET pin is not connected from STM32 to RS9116W EVK, then user need to press the RESET button on RS9116W EVK before free run.
Free run the project
Then continue the common steps from Section 5.3
5.2.2 Using EFx32#
Refer EFx32 Getting Started, for settin-up EFR & EFM host platforms
Import the EFR32/EFM32 project from
<SDK>/examples/snippets/ble/ble_ibeacon/projectsSelect the appropriate .slsproj as per Radio Board type mentioned in Section 3.3 for EFR32 board. (or)
Select the *.brd2204a-gg11.slsproj for EFM32GG11 board.
Compile and flash the project in to Host MCU
Debug the project
Check for the RESET pin:
If RESET pin is connected from EFx32 to RS9116W EVK, then user need not press the RESET button on RS9116W EVK before free run
If RESET pin is not connected from EFx32 to RS9116W EVK, then user need to press the RESET button on RS9116W EVK before free run
Free run the project
Then continue the common steps from Section 5.3
5.3 Common Steps#
After the program gets executed, Silicon Labs module would be in Advertising state.
Open iBeaconDetector app in the Smartphone and do Scan.
In the App, Silicon Labs module device would appear with the name configured in the macro RSI_BLE_LOCAL_NAME (Ex: "ibeacon") or sometimes observed as "SimpleBLEPeripheral".
After successful scan, user can see the Silicon Labs device advertised data i.e UUID, Maximum Number, Minimum Number and TX Power in iBeaconDetector application.
