XNUCLEOBNRG2A1 and NUCLEOU575

Hi,

I picked up a X-NUCLEO-BNRG2A1, and I am trying to communicate with it through a Nucleo-U575 Board. I basically generated a project template through CubeMX for the STM32U575 and included the BlueNRG-2 (X-CUBE-BLE2) Pack to include Bluetooth HCL/ACI APIs along with the project template. These are some images from cubeide. The project doesn't work...when the flow enters in MX_BlueNRG_2_Init,  hci_send_req function
returns BLE_STATUS_TIMEOUT. D7 pin and the pin #5 of the J12 on the X-NUCLEOBNRG2A1
expansion board are bridged. Is there something else to do in order to make all works together?thank you

Isabella

Hello @IVent.1 

 

It could be required to bridge D13 and D3 pins to set correctly SPI SCK.

Also with D3 and D13 connected, hci_send_req function returns BLE_STATUS_TIMEOUT.
