Dear community,

FW1.1.0 for SPWF04Sx series of Wi-Fi modules has been released! Please update your SPWF04Sx devices, so you can have the access to new features and fix for bugs and vulnerabilities. Link 

http://www.st.com/content/st_com/en/products/embedded-software/wireless-connectivity-software/stsw-wifi004.html

• WPA2 security in miniAP mode
• ECDH and ECDSA algorithms for TLS key exchange (ECC)
• MicroPython classes for TFTP, HTTP, SMTP, MQTT and WebSocket clients
• AT+S.FSM command for filesystem mount
• ramdisk_memsize configuration variable to set the length of RAM_disk
• 2 new GPIOs, 19 and 20, from module's bottom
• another PWM instance
• increased webserver capability, now able to support up to 4 parallel HTTP Post request
• support for 8MB SPI flash from Macronix

Moreover, WPA2 vulnerability has been fixed. This is a list of others fixes:

• garbage collector in microPython environment
• SPI management, including chip select, frame header, and CrLf removal from asynchronous events
• watchdog coming from AT+S.INPUTSSI command
• mixing output_demo WIND:57 with others synchronous (AT-S.event) events
• duplicated character at the end of MQTT WIND:86
• memory leak in AT+S.FSP command
• PWM reload

A few changes in backward compatibility have been introduced:

• WIND:29 in miniAP now adds STA MAC address
• PWM command now needs an ID, since a new instance has been added
• give an higher priority to SDCard, rather than RAM disk, when no path is specified
• SPI management of synchronous (AT-S.event) events now takes care of console_verbose configuration variable (set this variable to 0 to ensure fully compatibility with FW1.0.0)

Some bugs were found and raised also into this forum, so, thanks to you guys!

Last but not least, WIFI1 package FW3.1.0 for X-NUCLEO-IDW04A1 Wi-Fi shield has been released too. It adds MQTT, TFTP, Websocket and SMTP management. Link

For STM32+SPI users, please be sure to use FW3.1.0 of WIFI1 with FW1.1.0 of SPWF04.
