LoRaWAN_AT_Slave/STM32CubeIDE/Application/User/Core/sysmem.c STM32CubeIDE System Memory calls file @par Hardware and Software environment - This example runs on the STM32WLxx Nucleo boards. Both NUCLEO-WL55JC1 (HIGH-BAND) and NUCLEO-WL55JC2 (LOW-BAND) are suitable. - 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, lorawan_conf.h, lora_app.h, Commissioning.h, se-identity.h, mw_log_conf.h, main.h, etc - Careful: - the region and class chosen on LoRaWAN/App/lora_app.h shall be compatible with LoRaWAN/Target/lorawan_conf.h list -Set Up: -------------------------- V V -------------------------- | LoRa Object | | | | LoRa Network | | | | | | | ComPort<--| |--| |--| |-->Web Server | | | | -------------------------- -------------------------- @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 - Run the example - Open a Terminal, connected the LoRa Object - UART Config = 9600, 8b, 1 stopbit, no parity, no flow control - Terminal Config: Select 'CR+LF' for Transmit New-Line and switch 'Local echo' on - Reset the board - type AT? to get all available commands - Send your AT commands by typing them in the terminal @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 @par How to use MX to modify some RF middleware and application settings This example is compatible (with some problems/limitations) with STM32CubeMX and the RF application and middleware configuration can be modified via GUI. Few warnings and guidelines: - ioc file is provided in the project directory and can be opened with STM32CubeMX v6.7.0 or higher. - warning: when regenerating with the provided ioc file, the IDE projects are regenerated and paths to HAL and MWs files from STM32Cube/Repository location are erroneously added; to avoid that, user shall uncheck the "Use Default Firmware Location" in the GUI "Project-Manager" panel and shall replace "Firmware Relative Path" with the root directory of the STM32CubeWL firmware package (e.g. C:\myDir\STM32Cube_FW_WL_V1.3.0\); problem will be fixed in next STM32CubeMX version. - .extSettings file allows to add to the generated IDE projects additional files not generated natively by MX (e.g. BSP files). - when regenerating on existing code and existing linker files: - STM32CubeMX updates the existing project content and preserves linker files. - STM32CubeMX does not update the USER CODE sections (lines between /* USER CODE BEGIN Xxx */ and /* USER CODE END Xxx */). - when regenerating after copying only the ioc file in an empty directory: - STM32CubeMX generates default project files and default linker files. (Please check original linker file from project directory) - it is up to the user to to fill the USER CODE sections with his application code. @par How to use it with Azure ThreadX RTOS? This example can be combined with Azure ThreadX RTOS via STM32CubeMX.
