Hello! I welded the controller p-nucleo-wb55 on my board(out of debug board) and powered it how is described in the documentations, but bluetooth does not work(does not advertise). How can I solve this problem?

Do you mean you unsolder the chip from the Nucleo board and solder it on your own board?

Did you ensure the proper 50-Ohm matching of the antenna you are using on your board?

Did you prepare a correct matching network in between the RF out pin of the STM32WB device and the antenna available on your board?

The RF part is a critical part to ensure a proper communication with other devices that may not correctly receive the adverisement packets.
