Nucleo-L433RC-P board with a BlueNRG-2 BLE

Hi

I am testing the Nucleo-L433RC-P board with a BlueNRG-2 BLE interface. I configured the setup, but the BLE device is not being detected in the ST BLE app. Look at pic, Any modifications require are not ?

You'd need to show your code, too.

Does the app detect other things?

For a device to be detected, it must be Advertising.

Are you sure you have started advertising?

Hi Andrew

Ble are not showing in ST BLE Sensor app.

That doesn't answer any of the questions asked!

Hi Andrew

Check the configuration part, that is correct are not. Let me know.

Hi Andrew
BNRG2A1 BLE supports with Nucleo-L433 board are not.

Andrew Neil · ‎2025-06-14

Pardon?

We've been through all this before.

The BNRG2A1 just uses standard interfaces - SPI, UART, GPIO, etc.

It neither knows nor cares what microcontroller is used.

You said you have it working on a Nucleo-F401RE board - so use that as your reference.

Hi

I am trying to migrate the BNRG2A1 BLE module to other STM32 boards. It works perfectly with the Nucleo-F401RE board, but it doesn't work with other boards like the STM32F407VET6 or STM32L433RCT6P.

Currently, I am testing with the STM32L433RCT6P board, but the BLE is not being detected. I have thoroughly checked the .ioc configuration settings.
