Hello,
The concurrent mode (either static or dynamic) is not supported by CubeMX. If you want to use the static concurrent mode (BLE+Zigbee), you need to refer yourself to the following application project : Firmware\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE_Zigbee\BLE_Zigbee_Static. Refer to the associated readme.txt file for more details. The easiest way to develop an example of application using Zigbee/BLE static mode is start from the provided example.
Best Regards
