Correct WiFi firmware for B-L475E-IOT01A Discovery to connect to AWS

Have just spent a day or more going around in circles trying to connect the B-L475E-IOT01A Discovery to AWS using the code examples downloaded from the AWS console. Specifically the console reports the WiFi firmware need to be updated, despite having followed the update process. Also the WiFi does not connect to AWS. I have followed the instructions here: https://www.st.com/resource/en/utilities/inventek_fw_updater.zip and have watched the WiFi firmware program and verify however the firmware still reports as C3.5.2.5 not the required C3.5.2.5.STM. I am downloading the firrmware item: "New STM32L4 Discovery kit IoT node (B-L475E-IOT01A) ISM43362-M3G-L44-SPI-C3.5.2.5.STM SPI Firmware(unzip for bin file)". Any help welcomed.

C3.5.2.5 should be OK. maybe you have another problem. What does the application say on serial terminal ? could you give a log ?

are you using X-Cube-AWS ? what version ?
