Hi,I'm using the WB55RG-NUCLEO board,I upload the FUS and stack(1.16.4), I upload the firmware BLE TRANSPARENT MODE in cube IDE, In debug mode but when i step over HAL_GPIO_Init(GPIOA, &gpio_config) in MX_APPE_Init();,it says target is not responding

Hello,

By default the support of debugger is not supported in BLE_TransparentMode see the following define in app_conf.h file:

#define CFG_DEBUGGER_SUPPORTED    0

So, you have to set this define to 1 if you want to debug.

Best Regards
