STM WiFi module
The SPWFxxxx
series, of micro-sized intelligent Wi-Fi Modules, offers affordable an
easy Plug&Play solution for integration into IoT and standalone
802.11 b/g/n devices.
The modules are configured around a single-chip 802.11 transceiver with integrated PA and an STM32 32-bit microcontroller with extensive GPIO support, the modules also incorporate timing clocks and voltage regulators.
With, low power consumption and small form factor, the modules are ideal for both fixed and mobile wireless applications.

SILICA WiFi EvaBoard
The SILICA WiFi EvaBoard was developed by SILICA Italy to help customers to using the STM WiFi module.
The name of this board is: BRANCA BOARD (see below).
NOTE:
Now STM has released is WiFi EvaBoard (STEVAL-IDW001V1).
Also is available a Serial to USB (STEVAL-PCC018V1) bridge to connect with the STM EvaBoard.
STEVAL-IDW001V1 + STEVAL-PCC018V1
is equivalent to Silica Branca Board, this means that each example that use the USB interface, see the STM traning manual, can also be done with the Branch Board.

How to Update the SW on SILICA STM WiFi EvaBoard
The explanations on how to update the SW on the STM WiFi module via Flash Loader are here.
Please remember to use the last version of Flash Loader that is here.
Attention: the update of the SW on WiFi module via OTA is possible only on the modules that have Flash on board (SPWF01SA.11 and SPWF01SC.11).
Please remember to use the last version of Flash Loader that is here.
ATTENTION:
Up to now there is online the Flash Loader version 2.7 that has some problems to upload the FW on WiFi module.
STM will resolve the issue as soon as possible, at the moment use the Flash Loader release 2.6 that is here.

Again are available two different releases one for WiFi module with Flash and another one for WiFi module without Flash.
In the package are present a lot of new docs and examples.
The previus SW release ver.3.3 is available and are:
In the package are present a lot of new docs and examples.
User Manual ver.4, FootPrint, Tutorials (TLS (Transport Layer Security) and SSL (Secure Sockets Layer) protocol, Power Management, Socket Server, Dynamic Web Pages), etc.
NOTE:
New FeaturesNOTE:
The SSL/TLS protocols provide security for communications over networks.
The IETF standard body adopted SSLv3.0 with minor tweaks and published it as TLS version 1.0 (RFC 2246, 1999):
the two versions are very similar, but interoperability is precluded. TLSv1.2 (RFC 5246, 2008) is the latest and recommended version, which is superior because it offers flexibility and key features that were unavailable in earlier protocol versions.
All TLS versions were further refined (RFC 6176, 2011) removing their backward compatibility with SSL such that TLS sessions will never negotiate the use of SSLv2.0.

* Removed block for scan in miniAP mode
* Added possibility to fast reconnect to the last associated AP
* Force TCP/IP stack to immediately output packets received by TCP socket server into Data Mode. This means high throughput
* Updated WIND:28 showing if incoming STA is going to re-associate
* Signal how many STA are associated to miniAP through blink_led
* Added WIND:75 to WIND:79 to signal different kind of association failures (rejections, time outs, and low memory)
* Added commands for ADC, DAC and PWM usage
* Extended remote.html webpage, managing ADC, DAC and PWM peripherals
* Updated WIND:5 showing reason of HW failure
* Extended remote.html webpage, managing set configuration variables
* Extended devsts, devconf, and peers SSIs, sopporting specific field from status, configuration, and peers table. Use ":field" for status and configuration, and ":number:field" for peers, as postfix
* Added apredirect lwip config variable, allowing user to select his own redirected homepage in miniAP
* Extended input_demo SSI mechanism, supporting customer defined tags
* Added wait_timeout lwip config variable, allowing user to set the amount of time in time_wait state
* Added optional parameter to FSC command, allowing user to select if HTTP header if going or not to be part of the FSA payload
* and more...

Regenerate the FW inside the WiFi module
If you are loaded the new WiFI SW release on wrong address it is not
possible reboot the WiFi module.
If you are in this condition, please use this FW:
WiFi_FW_Start_From_Scratch
and reload it on WiFi module via JTAG using the ST-LINK-v2 and ST-LINK-Utility starting from the address 0x08000000.
After this, reload the last SW version using the standard procedure.
