B-L475E-IOT01A how to connect to AWS

Hi

 

Is anyone using the B-L475E-IOT01A with the AWS from amazon as mentioned in the documentation?

 

I have problems getting it to work. I have the same problem with the default firmware which has been delivered and the one I compiled myself.

I use attolic truestudio and I have imported the example project provided in en.x-cube-aws.zip

The only thing I changed in the exmaple project is I have increased the debug level.

I created the AWS account and created the certifiacted and "thing" as shown in the video and written in the handout en.STM32L4_Discovery_Kit_IoT_Node_Hands_on.

 

The Wifi connection works. I get an IP from the dhco server.

The controller is able to get the time from a server. Althoug ssl_tls returns an error the time is delivered.

For me it seems ssl in general is working.

 

In the next step the conenction to AWS should be done.

Starting there I get a lot of errors. With wireshark I was able to detect there is a connection attempt. The amazon interface shows there are connection attempts. Unfortunatly none of them was successful.

 

I have attached the terminal output.

 

Can anybody give me a hint how to proceed?

 

Thank you very much!
