On a NUCLEO-WB55RG board, I've flashed the Wireless Coprocessor with stm32wb5x_BLE_Zigbee_FFD_dynamic_fw binary at address 0x08077000 (firmware version 1.16.0). Then I run BLE_Zigbee_Dyn example, but the application failed.

[BBlin.1]

On HyperTerminal, I just see :

[M4 APPLICATION] ConcurrentMode = 0

[M4 APPLICATION] ==> Start_BLE

On debugging, the software infinity loops on BLE stack starting up on CPU2 in :

-> APP_BLE_Init

-> SHCI_C2_BLE_Init

-> shci_send

-> shci_cmd_resp_wait

-> UTIL_SEQ_WaitEvt : whille loop on line 447

Is there any extra operation to do before using this example code ?

Have you any idea why this loop occurs ?

Thanks in advance.

My mistake : I've used BLE_Zigbee_Dyn example from version 1.14.1
