HI ST Team,
Concerning the GitHub issue https://github.com/STMicroelectronics/STM32CubeWB0/issues/6
In AN5289 – "How to build wireless applications with STM32WB MCUs", Table 1 lists multiple BLE stack options for STM32WB5x devices, including:
- stm32wb5x_BLE_Stack_full_fw.bin
- stm32wb5x_BLE_Stack_light_fw.bin
In the current lib https://github.com/STMicroelectronics/STM32CubeWB0/tree/main/Middlewares/ST/STM32_BLE/stack/lib, only these static libs are present:
- stm32wb0x_ble_stack.a
- stm32wb0x_ble_stack_controller_only.a
There is no separate stm32wb0x_ble_stack_light.a, which is expected as the lightweight alternative to the full BLE stack.
Clarification Request:
- Can you please confirm if the *_controller_only.a is the intended lightweight replacement for the missing light.a?
- If yes, can you kindly update the GitHub folder README or documentation to reflect this equivalence (i.e., "controller only.a is functionally similar to the BLE light stack")?
- If not, can the missing light.a A variant be added?
This would help developers optimise for RAM-constrained devices like the STM32WB05 (24KB RAM), especially when targeting single-link BLE applications.
Thank you for the clarification and support!
