Bluetooth communication - X-NUCLEO-WB05KN1 & NUCLEO-L476RG

[luckyluc1908]

Hello, everybody!

As you can see from the name of the subject, I am currently working on a bluetooth communication between an stm32-nucleo-l476rg and an extension board x-nucleo-wb05kn1.

To this day, I have a code that seems quite coherent and functional. However the problem lies in the configuration of my boards, indeed, the configuration in CubeMX is more idfficile than expected between this board and the extension. I’m looking to use USART and I wanted to learn about the configuration of my TX and RX (pin PA2 and PA3) but I think missing parameters because the connection is still not done. In addition, I have the impression that my wb05kn1 is in 'sleep' mode and I don’t know how to reactivate it.

Every attempt to verify connection is a failure and I have no feedback from my module. Do you have solutions for the software settings and module focus?

Thank you in advance!

Hello @luckyluc1908 

First, are you working on connecting a NUCLEO-L476RG to a X-NUCLEO-WB05KN1 throw BLE or are you trying to establish a connection between the NUCLEO-L476RG as a host and a X-NUCLEO-WB05KN1 throw USART. If it is the first case, you should be aware that the X-NUCLEO-WB05KN1 need a Host to work (a NUCLEO-U575ZI for example). For the second case, I suggest you use the X-CUBE-WB05N throw CubeMX and follow the implementations of the available examples on the same package for the NUCLEO-U575ZI (they should be helpful). Also, the UM3406 should be a good guide.

Best Regards.
