BlueNRG-2 with STM32F411 not working

[kaushika]

Hi,
I am working on a project that needs Bluetooth support. 

Our main MCU: STM32F411CE.
Bluetooth module: BlueNRG-2 (Brought a BLUENRG-M2SP module and then fabricated a simple custom breakout board)

Initially, I tried to use the official example project from STM32CubeIDE (Beacon, Central, and SensorDemoBLE). But it is not working. I could not discover any signal through a BLE scanner. 

But I tried to read BLUENRG-M2SP directly using ST-Link and the RF Flasher utility. It worked.
I checked the SPI lines of the MCU using a logic analyzer, but I could not read any signal. Why does the MCU not send any data to the Bluetooth chip?
How do I set it as workable? Is there any simple example to power up this module?

Hello @kaushika and welcome to the community;

Please make sure that the SPI lines (MOSI, MISO, SCK,.....) are correctly connected.

Could you please share the SPI configuration.

Thank you.
