Hi all
STM32WB55RG nucleo board
zephyr (3.0)
When BLE stack is enabled, it becomes halt.
Can't I use LSI clock to make the BLE stack run ?
We made a sample board, but We didn't attach an LSE.
So. use LSI clock.
If We use LSE in nucleo , it will behave normally, and if We use LSI, it will be halted.
I want to disable stop mode, but I don't know how in zephyr
Do you have any idea ?
Thanks

Hello,
On STM32WB55RG, you can only use LSE or HSE/1024 clock for RF system wake up clock. In your case, you should use HSE/1024. Only on STM32WB15, you can use LSI clock for RF system wake up clock.
Best Regards
