Do you have anything else connected to the device - Please make sure that STM workbench, Terminal program etc. are all closed while you try to update the WiFi firmware.
You can remove the project level define USE_OFFLOAD_SSL and then the code should work with the old firmware as well. However, it will significantly impact performance as it will start doing TLS in software. We highly recommend updating the WiFi firmware.
Thanks.
