WiFi-ISM43362-M3G-L44

Arduino library to support the Wi-Fi module Inventek ISM43362-M3G-L44 (802.11 b/g/n)

API

The API is based on the Arduino WiFi API. Refer you to the documentations at https://www.arduino.cc/en/Reference/WiFi

List of the adaptations:

WiFiST

• Class constructor changed, 3 new constructors depend on the communication driver: WiFiClass(SPIClass \*SPIx, uint8_t cs, uint8_t spiIRQ, uint8_t reset, uint8_t wakeup); WiFiClass(HardwareSerial \*UARTx, uint8_t reset, uint8_t wakeup); WiFiClass(uint8_t tx, uint8_t rx, uint8_t reset, uint8_t wakeup);
• status(): less verbose; only WL_CONNECTED, WL_NO_SHIELD, WL_IDLE_STATUS, WL_NO_SSID_AVAIL, WL_SCAN_COMPLETED, WL_CONNECT_FAILED implemented.
• setMac(): function added to set MAC address of the Wifi module.

WiFiClientST :

• available(): not supported. Always returns 1.
• peek(): not supported. Always returns 0.
• flush(): empty function. Do nothing (already empty in Arduino Wifi API).

WiFiUdpST:

• endPacket():The data are sent when you call write(). By default, do nothing and always return 1. If true is passed as argument the client connection started by beginPacket() is closed.
• available(): not supported. Always returns 0.
• parsePAcket(): not supported. Always returns 0.
• peek(): not supported. Always returns 0.
• flush(): Do nothing (already empty in Arduino Wifi API).

WiFiServerST:

• status(): Do nothing (always returns 1).

Version

Important

The WiFi library is based on FW "Inventek eS-WiFi ISM43362-M3G-L44-SPI C3.5.2.5.STM".

Caution

• WiFiServerST is not stable due to issue of the current WiFi firmware version: C3.5.2.5.STM
• WEP-128 is not functional. Issue probably due to the current WiFi firmware version: C3.5.2.5.STM
• UDP server is not functional with the current WiFi firmware version: C3.5.2.5.STM while it was with FW version C3.5.2.3.BETA9 (#12)

To update the Inventek ISM-43362 Wi-Fi module firmware, please read the readme file for instructions include in this archive: https://www.st.com/resource/en/utilities/inventek_fw_updater.zip

Supported Secure Wi-Fi authentication by the Wi-Fi module Inventek ISM43362-M3G-L44:

• WEP-128
• WPA-PSK (TKIP)
• WPA2-PSK

Examples

The examples are close of the Arduino WiFi library but with some adaptations to work with the ISM43362-M3G-L44 WiFi module.
