@par Example Description
How to control remote LEDs with BLE LLD.
@note The objectives are to communicate using BLE_LLD between 2 boards,
in BLE Radio format not BLE Stack protocol.
BLE_LLD_Pressbutton can use 2 terminals to display communication between 2 boards.
BLE_LLD_Pressbutton can be used with BLE_LLD_Lowpower.
But Appli is based to show in a very simple way a communication between 2 boards:
It is based on pressing button and blinking answer
@note BLE_LLD is a 2-level stack implemented just over the Hardware and Radio layer.
Lowest Layer also called Low Level or LL
It is just over the Hardware and Radio Layer.
It contains all the API to Set/Configure/Initialize all the parameters for Sending/receiving BLE Radio format packet data
Over LL layer there is HAL level
It contains a reduced number of API to Send/Receive BLE Radio format packet with predefined parameters
It works by calling a set of LL API
It make simple and fast to Send/Receive Packet
But It does allow the user to change all the Radio parameters
@note LL is for user that want to customize the Radio and BLE parameters, it is more complex to implement
HAL is for user that want to Send/Receive in a very simple way less complex, without configuring LL
ble_lld module contains LLD API HAL and LL API
app_ble_lld module contains Transport Layer Command call from CPU1 to CPU2 + Buffer management + IT Radio management from CPU2

@par Hardware and Software environment
- This application uses two STM32WB55xx devices.
- This example has been tested with an STMicroelectronics STM32WB55RG-Nucleo
board and can be easily tailored to any other supported device
and development board.
- On STM32WB55RG-Nucleo, the jumpers must be configured as described
in this section. Starting from the top left position up to the bottom
right position, the jumpers on the Board must be set as follows:
CN11: GND [OFF]
JP4: VDDRF [ON]
JP6: VC0 [ON]
JP2: +3V3 [ON]
JP1: USB_STL [ON] All others [OFF]
CN12: GND [OFF]
CN7: <All> [OFF]
JP3: VDD_MCU [ON]
JP5: GND [OFF] All others [ON]
CN10: <All> [OFF]
@par How to use it ?
In order to make the program work, you must do the following:
- Connect 2 STM32WB55xx-Nucleo boards to your PC
- Open your preferred toolchain
- Rebuild all files and load your image into one target memory
- Rebuild all files of BLE_LLD/BLE_LLD_Pressbutton application
and load your image into the other target memory
+ load stm32wb5x_BLE_LLD_fw.bin
- Run the application
BLE_LLD_Pressbutton used only HAL API for Send/Receive
If you want to control this application, you can press buttons
In this order and described into main.c:
After power On or Reset (ALL the LED are OFF) all the Boards are in Received mode
1) Press button SW on first board to interrupt Received mode and Send LED number to second board:
-SW Number 1 (SW1) for LED Number 1 (LED1)
-SW Number 2 (SW2) for LED Number 2 (LED2)
-SW Number 3 (SW3) for LED Number 3 (LED3)
2) When Second board Receive LED number:
-LED1 : LED1 is Toggling
"Led 1 is Toggling" is print
-LED2 : LED2 is Toggling
"Led 2 is Toggling" is print
-LED3 : LED3 is Toggling
"Led 3 is Toggling" is print
3) To Switch off the LED press Reset or press the SW Number corresponding of the LED that is ON
