BlueNRG-M2 no SPI signals

[attemptx]

Hello,

I am currently working with a BlueNRG-M2 module and STM32L433CC. I am unfortunately struggling right at the beginning.....

I tried the example codes generated with CubeMX but nothing worked.

So I tried to write my own code in a test project with FreeRTOS.

First I call the hci_init(); function and everything seems to be executed as it should from what I could observe through debugging.

Then hci_reset(); follows to reset the module and nothing appears on the SPI lines.

I have read in this forum that hci_send_req(); should communicate through SPI with the module and then wait for an event, but nothing is happening.

Does anyone have an idea?

I followed all the "Getting Started" documentations with step-by-step guide for CubeMX but it won't work.

An answer would be appreciated.

Best regards

Clément
