How to make this work:
- Obtain a NUCLEO-STM32WB55 from your preferred supplier.
- Download and Install STM32CubeProgrammer.
- Download stm32wb5x_FUS_fw.bin, stm32wb5x_BLE_Stack_full_fw.bin, and Release_Notes.html from
gh:STMicroelectronics/STM32CubeWB@2234d97/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x
- Open STM32CubeProgrammer
- On the right-hand pane, click "firmware upgrade" to upgrade the st-link firmware.
- Once complete, click connect to connect to the device.
- On the left hand pane, click the RSS signal icon to open "Firmware Upgrade Services".
- In the Release_Notes.html, find the memory address that corresponds to your device for the stm32wb5x_FUS_fw.bin file
- Select that file, the memory address, "verify download", and then "Firmware Upgrade".
- Once complete, in the Release_Notes.html, find the memory address that corresponds to your device for the
stm32wb5x_BLE_Stack_full_fw.bin file. It should not be the same memory address.
- Select that file, the memory address, "verify download", and then "Firmware Upgrade".
- Select "Start Wireless Stack".
- Disconnect from the device.
