@par Description
This directory contains a set of source files that implements a Ping-Pong application
between two PingPong Devices.
The PingPong Device can be
- a STM32WL Nucleo board
- a Lora Radio expansion board or a B-L072Z-LRWAN1
It is a simple RX/TX RF link between the two PingPong Devices, one will called be Ping the other will be called Pong.
By default, each PingPong Device starts as a master and will transmit a "Ping" message, and then wait for an answer.
The first PingPong Device receiving a "Ping" message will become a slave and answers the master with a "Pong" message.
At start, on STM32WL Nucleo board, if you see the 3 LEDs blinking on the 2 PingPong Device
it means that both boards have their RX windows synchronised (and TX windows too). The RX window of the first board
should NOT be perfectly synchronised with the second board, there should be one TX window in front of one RX window.
You only have to reset one of the two boards, to get rid of this issue.
When boards are sending and receiving: Blue LED blinks on "Ping" msg received, Red LED blinks on "Pong" msg.

@par Hardware and Software environment
- This example runs on the STM32WLxx Nucleo board.
- STM32WLxx Nucleo board Set-up
- Connect the Nucleo board to your PC with a USB cable type A to micro-B
to ST-LINK connector.
- Please ensure that the ST-LINK connector jumpers are fitted.
- Configure the software via the configuration files:
- sys_conf.h, radio_conf.h, mw_log_conf.h, radio_board_if.h, main.h, etc
- Careful:
- STM32WLxx Nucleo requires IS_TCXO_SUPPORTED=1
-Set Up:
-------------------------- V V --------------------------

@par How to use it ?
In order to make the program work, you must do the following :
- Open your preferred toolchain
- Rebuild all files and load your image into target memory
- Do the same for second board
- Reset the two boards
- Run the example on two boards
- Open two Terminals, each connected to their respective PingPong Device
- UART Config = 115200, 8b, 1 stopbit, no parity, no flow control
