ISM43362 WiFi driver for mbed-os

The mbed OS driver for the ISM43362 WiFi module

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

Currently supported platforms

ISM43362 module is soldered on the following platforms from STMicroelectronics

Configuration

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

Debug

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

Options

Country code can be specified by using the "ism43362.wifi-country-code" parameter of mbed_app.json.

The default country code = US (USA)

Link between code and country is here : https://www.juniper.net/documentation/en_US/release-independent/junos/topics/reference/specifications/access-point-ax411-country-channel-support.html

Useful to use all the Radio Channels available in a country.

Firmware version & firmware update

The recommended firmware version is ISM43362-M3G-L44-SPI-C3.5.2.5.STM

The utility to upgrade firmware on B-L475-IOT01A and B_L4S5I_IOT01A boards can be found here: https://www.st.com/resource/en/utilities/inventek_fw_updater.zip

It contains instructions and URL where to get firmware from (https://www.inventeksys.com/iwin/firmware/)

Note that only Wifi module from DISCO_F413ZH cannot be updated (HW limitation).
