STM32-Hotspot/Menu System Firmware Package, based on STM32CubeWL Release v1.2.0

Example

This Hotspot FW package includes:

• Application example under "Projects\NUCLEO-WL55JC\Applications\SubGHz_Phy" called MenuSystem.
  • This example introduces a Menu Interface for transmitter (and/or receiver) application between two STM32WL55xx devices (note, two NUCLEO-WL55JC1 are needed; for the Tx and Rx, respectively). The Tx device transmits a short 10 byte packet every 2s if in TX_Multiple Radio Mode, and the Rx device receives these packets and displays the payload on the OLED display.
  • Development tools, toolchains/compilers: STM32CubeIDE v1.8.0
  • Supported Devices and hardware boards: NUCLEO-WL55JC1
  • Known limitations: None

Hardware and Software Requirements

• HARDWARE:
  • Two NUCLEO-WL55JC1
    • NUCLEO-WL55JC
  • Two Micro-USB cables
  • Two SSD1306 OLED displays
• SOFTWARE:
  • STM32Cube IDE v1.8 and higher
  • STM32Cube_FW_WL_V1.2.0 Firmware Package

Set Up

• Install STM32 CubeEcosystem tools (STM32Cube IDE)
• Download the Menu-System Firmware binary file from STMicroelectronics MFT
• Attach the OLED Displays on the Nucleo-STM32WL55 Boards
• Drag the .bin file onto the Nucleo-STM32WL55 board.
• Do the same for both Nucleo-STM32WL55 Boards with the Firmware
