@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. The video tutorial:
"STM32WL - How to port an existing RF application on Azure ThreadX RTOS"
