I'm trying to use the STMicroelectronics.X-CUBE-BLE2 version 3.2.2 to test my BLUENRG-232N device. But the mcu goes into the Infinite_Loop: during the call of the MX_BlueNRG_2_Init function

I'm working on a new IOT device. I'm using your BLUENRG-232N device with STM32L496AGI6 microcontroller, and I'm using your STMicroelectronics.X-CUBE-BLE2 version 3.2.2 stack for the firmware and the application. but unfortunately the mcu goes into the Infinite_Loop: during the call of the MX_BlueNRG_2_Init function. 

Find attached the demo_project and schematic.

Hello,

from your ioc I see you did not enable the EXTI line3 for the BlueNRG interrupt.

You should enable it as shown in the attached picture.

 

The EXTI line[15:10], also enabled in the picture, is used for the User Button that is configured in EXTI mode.

Please, let me know if this solve your issue.
