STM32WL firmware installation

Download the STM32WL firmware from STSW-ST25DV010.
This package contains the bootloader (source code and binary) and the firmware (source code and binaries for
the European region).
• For the bootloader, it is not necessary to recompile it, use directly as provided.
• For the STM32WL firmware: For the European region, the binaries are provided in the STSW-ST25DV010
package and can be used directly. For other regions, the firmware must be personalized and recompiled.

Firmware personalization

The current demonstration is by default configured for:
• European region (868 MHz frequency plan)
• ant7-t-25dv64kc board
Before compiling the firmware, customize the frequency plan and the hardware board used.
