The mbed OS driver for the ISM43362 WiFi module

https://www.inventeksys.com/products-page/wifi-modules/ism4336-m3g-l44-e-embedded-serial-to-wifi-module/

ISM43362 module is soldered on the following platforms from STMicroelectronics

• DISCO_L475VG_IOT01A
• DISCO_F413ZH

Correct pins have already been configured for both supported platforms.

Here is configured pins:

• MBED_CONF_ISM43362_WIFI_MISO : spi-miso pin for the ism43362 connection
• MBED_CONF_ISM43362_WIFI_MOSI : spi-mosi pin for the ism43362 connection
• MBED_CONF_ISM43362_WIFI_SPI_SCLK : spi-clock pin for the ism43362 connection
• MBED_CONF_ISM43362_WIFI_SPI_NSS : spi-nss pin for the ism43362 connection
• MBED_CONF_ISM43362_WIFI_RESET : Reset pin for the ism43362 wifi module
• MBED_CONF_ISM43362_WIFI_DATAREADY : Data Ready pin for the ism43362 wifi module
• MBED_CONF_ISM43362_WIFI_WAKEUP : Wakeup pin for the ism43362 wifi module

Some debug print on console can help to debug if necessary.

• in ISM43362Interface.cpp file, set ism_interface_debug to 1
• in ISM43362/ISM43362.cpp file, set ism_debug to 1
• in ISM43362/ATParser/ATParser.cpp file, there are 3 different level : dbg_on / AT_DATA_PRINT / AT_COMMAND_PRINT

Another way to enable these prints is overwrite MBED_CONF_ISM43362_WIFI_DEBUG in your json file: "ism43362.wifi-debug": true

This driver has been tested with C3.5.2.2 and C3.5.2.3.BETA9 firmware version

Only Wifi module from DISCO_L475VG_IOT01A can be updated (HW limitation for DISCO_F413ZH).
