I want to connect my NUCLEO board via bluetooth to a RN42 bluetooth module. The RN42 recieves sensor data from an adruino and needs to send it wirelessly to my STM board. How can i go about connecting the two?

Then you need to re-think your design ?

The STM32WB doesn't support Bluetooth Classic; the RN42 doesn't support BLE - so they are not compatible.

You're going to have to change (at least) one of them!

Isn't the RN42 "classic" Bluetooth - not BLE ?

:thinking_face:

Note that RN42 is Not Recommended For New Designs (NRND) as it cannot be certified for new products:
