Hello Dear Person,

Hello @melihakalin 

First it may be broken but let's do some checks before. First, please update your FUS and Stack to the last Versions using the binary files from the STM32CUBEWB V1.20.0 (Don't forget to click on the button "Start wireless stack" after updating the FUS and STACK). If you still have a problem, please upload the content of all your option bytes. You can also take a look at the FAQ of this WIKI (last part) it should be helpful.

Best Regards.
