+# STM32WB family
+
+[st.com STM32WB family page](https://www.st.com/en/microcontrollers-microprocessors/stm32wb-series.html)
+
+This ST MCU family is dual-core : based on an Arm Cortex-M4 core and an Arm Cortex-M0+ core.
+
+- M4 core is dedicated to application (mbed-os)
+- M0 core is dedicated to BLE FW (only binary, source files not provided)
+
+# Supported boards
+
+## NUCLEO_WB55RG
+
+[st.com STM32WB55RG MCU page](https://www.st.com/en/microcontrollers-microprocessors/stm32wb55rg.html)
+
+[st.com NUCLEO page](https://www.st.com/en/evaluation-tools/p-nucleo-wb55.html)
+
+- Total FLASH is 1MB, but note that it is shared by M4 and M0 cores.
+    - mbed-os application size is then limited to 768 KB
+
+- RAM: 256 KB
+    - SRAM1: 192 KB
+    - SRAM2a: 32 KB
+    - SRAM2b: 32 KB
+
+
+# BLE
+
+## MBED-OS support
+
+BLE feature is based on Cordio stack and API (above HCI) implementation.
+
+Note that the BLE controller firmware running on the cortex-M0 is the same as in STcubeFW solution
+
+- within mbed, the controller will run only the below-HCI part
+- within STcubeFW (and STM32WPAN middleware), it can run also up to GATT / GAP layers ...
+
+## mbed-trace support
+
+trace group: BLE_WB
+
+example:
+````
+[INFO][BLE_WB]: WIRELESS COPROCESSOR FW VERSION ID = 1.4.0
+[INFO][BLE_WB]: WIRELESS COPROCESSOR FW STACK TYPE = 1
+[DBG ][BLE_WB]: mbox_write type:1, len:3
+[INFO][BLE_WB]: TX>> BLE CMD
+[DBG ][BLE_WB]:   Type 0x1
+[DBG ][BLE_WB]:    Cmd 0xc03
+[DBG ][BLE_WB]:    Len 0D]

+## BLE FW flashing procedure
+
+Release Note and complete flashing procedure:
+https://htmlpreview.github.io/?https://github.com/STMicroelectronics/STM32CubeWB/blob/master/Projects/STM32WB_Copro_Wireless_Binaries/Release_Notes.html
+
+
+- STEP 1: Use STM32CubeProgrammer
+
+https://www.st.com/en/development-tools/stm32cubeprog.html
+
+````
+FLASHPATH="C:\Program Files (x86)\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin"
+export PATH=$FLASHPATH:$PATH
+````
+
+- STEP 2: Access to Bootloader USB Interface (system flash)
+
+    * Boot0 pin set to VDD : Jumper between CN7.5(VDD) and CN7.7(Boot0)
+    * Jumper JP1 on USB_MCU
+    * Power ON via USB_USER
+
