@par Application Description
How to use the OnOff cluster with persistent data activated on a device acting as Router within a Centralized Zigbee network.
The purpose of this application is to show how to create a Zigbee centralized network, and
how to communicate from one node to another one using the OnOff cluster. Once the Zigbee mesh
network is created, the user can send requests from the client to the server through the push button
in order to make the LED toggling and with a restart from persistence of remote device.
For this application it is requested to have:
- 1 STM32WB55xx board loaded with:
- wireless coprocessor : stm32wb5x_Zigbee_FFD_fw.bin
- application : Zigbee_OnOff_Coord_NVM
- 1 or more STM32WB55xx board loaded with:
- wireless coprocessor : stm32wb5x_Zigbee_FFD_fw.bin
- application : Zigbee_OnOff_Router_NVM

-------- ---------
To setup the application :
a) Open the project, build it and load your generated application on your STM32WB devices.
To run the application :
a) Start the first board. It must be the coordinator of the Zigbee network so in this demo application it is
the device running Zigbee_OnOff_Coord_NVM application (Device2 in the above diagram).
If the device starts from persistent data, the GREEN LED should light ON.
If the device doesn't start from persistent data, the BLUE LED should light ON.
Note: By pressing on SW2, it is possible at any time to delete the persistent data. At this stage, fresh start will be done
on the next restart.
Start the second board. This board is configured as Zigbee router with persistence and will attached to the network created
by the coordinator. Do the same for the other boards if applicable.
b) At this stage the second board tries to start from persistence this leads to two choices:
- Persistent Data read from NVM are valid -> the router takes back is role in the network and restore the on/off cluster
attribute saved in NVM (RED LED on or off). GREEN LED is ON indicating a restart form persistence.
- No Persistent data found or wrong data,a fresh start is performed, the Zigbee network is automatically created
and BLUE LED is ON.
It is now possible to send OnOff Cluster commands from the client to the server in multicast mode
by pressing on the SW1 push button.
You must see the RED LED toggling on the server side. (this for all devices). Persistence Data are updated in NVM. Stack and cluster
attribute (RED LED state).
c) If the user power cycle the Device 1, Persistent Data are read back and cluster attribute (RED LED state) restored.
The device start from persistence and GREEN LED is on.
Pushing SW1 on any boards toggle RED LED.
d) Push Button SW2 is used to delete NVM (fresh start will be done on next start up ,reproduce a))
e) Push Button SW3 is used to run a NVM diagnostics (flash test)
Note: when LED1, LED2 and LED3 are toggling it is indicating an error has occurred on application.

@par Hardware and Software environment
- This example runs on 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 ?
=> Loading of the stm32wb5x_Zigbee_FFD_fw.bin binary
This application requests having the stm32wb5x_Zigbee_FFD_fw.bin binary flashed on the Wireless Coprocessor.
If it is not the case, you need to use STM32CubeProgrammer to load the appropriate binary.
All available binaries are located under /Projects/STM32_Copro_Wireless_Binaries directory.
Refer to UM2237 to learn how to use/install STM32CubeProgrammer.
Refer to /Projects/STM32_Copro_Wireless_Binaries/ReleaseNote.html for the detailed procedure to change the
Wireless Coprocessor binary.
=> Getting traces
To get the traces you need to connect your Board to the Hyperterminal (through the STLink Virtual COM Port).
The UART must be configured as follows:
- BaudRate = 115200 baud
- Word Length = 8 Bits
- Stop Bit = 1 bit
- Parity = none
- Flow control = none
=> Running the application
Refer to the Application description at the beginning of this readme.txt
