+Bluetooth and compatibility with STM32WB Copro Wireless Binaries
+================================================================
+
+To operate bluetooth on Nucleo WB55RG, Cortex-M0 core should be flashed with
+a valid STM32WB Coprocessor binaries (either 'Full stack' or 'HCI Layer').
+These binaries are delivered in STM32WB Cube packages, under
+Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x/
+To date, interoperability and backward compatibility has been tested and is
+guaranteed up to version 1.5 of STM32Cube package releases.
