@par Description
This directory contains a set of source files that implements a PER (Packet Error Rate) tests application
with IBM whitening between one Tx device and one Rx device.
Tx device:
- in /SubGHz_Phy/App/subghz_phy_app.c update #define TEST_MODE to RADIO_TX, compile and load
- packet content is : preamble | sync | payload length | payload | crc
+ crc calculated using payload length and payload
+ whitening is calculated over payload length | payload | crc
- the transmission starts forever in GFSK 50kbit/s with a payload of 64 bytes
- user button 1 increments "packet length" by 16 bytes
- user button 2 increments "packet length" by 1 bytes
- user button 3 toggles packet "payload mode" from ramp (0x00, 0x01..) to prbs9
- LED blue on while radio in Tx
Rx device:
- in /SubGHz_Phy/App/subghz_phy_app.c update #define TEST_MODE to RADIO_RX, compile and load
- LED green on when Rx OK, LED red when Rx KO

@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, main.h, etc
-Set Up:
-------------------------- V V --------------------------
| Tx Device | | | | Rx Device |
| | | | | |
ComPort<--| |--| |--| |-->ComPort
| | | |
-------------------------- --------------------------
@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 Tx or Rx Device
- UART Config = 115200, 8b, 1 stopbit, no parity, no flow control
@par How to debug ?
- make sure the flag DEBUGGER_ENABLED to 1 in sys_conf.h
- simpler to define the flag LOW_POWER_DISABLE to 1 as well
- compile, download and attach
