IDW01M1 via nucleo 401RE serial communication

Hello,

I am trying to follow the 6LoWPAN Tutorial at 

https://blog.st.com/tutorial-6lowpan-guide-creating-network-sending-data-internet/

. I have the same hardware as in the tutorial. Unfortunately, I can't find how to check the software version on the X-Nucleo IDW01M1 module via serial communication (1.3.1 Checking the Wi-Fi Module�s firmware). Nothing shows up on the serial emulator (except some wrong characters). I tried to change the speed, but none work. With some example code, I checked that I'm able to communicate with the Nucleo 401RE and the IDW01M1 (Hello world code).

The only thing that differs in what I do is the X-CUBE-WIFI1 version which is now 3.1.1 instead of 2.1.1 in the tutorial. Does someone has the same issue? Can it be a hardware problem?

Regards,

Clement

Hi !

The example lists the wrong baud rate (115200). Use 921600 instead and it will work.

Cheers !
