STM32WB Bluetooth is Not Working

Hello ST,

Same thing is happening to me also, I had taken reference of MB1293 board that what I had put in my design too.

The only difference in the reference and my design is of MCU part no i.e., STM32WB55CGU6U (Reference board MCU) and STM32WB55CGU6 (Used in my design).

But the problem is that, in a reference board a band pass filter (FLT1) is not connected and that do so in my board too. And Reference board is getting Bluetooth signal but not in mine board.

So my question is that, after connecting the band pass filter(FLT1) my design should I able to receive a Bluetooth signal? Or have to change something in API?

If not, please suggest some solution for the same, if I have to change some thing in my design or else what you know about it.

Here I am attaching some images of reference board and my board along with the schematic.

Please Suggest some solution for this as I also looking from my side.

Thanks - Soham Mistry.
