Hi Team,

We are using the Stm32wb55 series for our project and how to load the BLE Stack file through this programmer and which hex file we need to load for our board like

stm32wb5x_BLE_Stack_full_extended_fw.bin (or) stm32wb5x_BLE_Stack_full_fw.bin (or) stm32wb5x_BLE_Stack_light_fw.bin for our board.

Is there any upgrade document please share it with us.

Regards,

Srinivas.V

stm32wb5x_BLE_Stack_full_fw.bin is the main one supporting both master and slave roles on different links (with the limitation of max 8 links in parallel, from which max 2 slave links to master devices).

stm32wb5x_BLE_Stack_light_fw.bin is a reduced version of the previous supporting only 2 peripherals. It will just advertise, and accept incoming connection request from other master devices (e.g. Smartphone) (Slave up to 2 links).

stm32wb5x_BLE_Stack_full_extended_fw.bin has more features supporting BLE Extended advertising.

Note that to use this binary, it is necessary to adapt the scatter file in the BLE applications.

You can find more information in the release notes located in the CubeWB FW package under directory STM32Cube_FW_WB_VX.Y.Z/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x
