                    ##### IMPORTANT NOTE #####
  ==============================================================================

  This application requests having the stm32wb5x_Mac_802_15_4_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 following directory:
  /Projects/STM32_Copro_Wireless_Binaries

  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.
