Not receiving VS_HCI_C2_Ready

VBess.1 · ‎2025-03-24

Hello,

I'm trying to implement a custom BLE Client on a P-Nucleo-WB55 board. The ST P2p_client example runs fine on the board and I could add some traces and do little modifications in it before trying to start my project from scratch with CubeMX. It seems the VS_HCI_C2_Ready is not received in my project since I never reach a breakpoint in IPCC_C1_RX_IRQHandler. I have checked many times the differences (clocks, code generated, initialisations...) between the P2P example and my project. I don't know what more to check. Since the example runs fine, I guess it's not a stack firmware problem.

If a kind soul could enlighten me...

Thanks.

Ooops, yes of course. I should have done that in the first post.

Thanks for your quick answer.

Hello,

I tried your project and it is working on my side. Can you please try it again?

Please erase full chip flash memory and reflash the BLE stack. After uploading the BLE stack, click on "Start Wireless Stack" button and try to run your application again.

Best regards,
