WIFI driver code

https://github.com/ARMmbed/wifi-ism43362

Add this wifi driver in your mbed-os directory :

cd mbed-os
git clone https://github.com/ARMmbed/wifi-ism43362.git

STM32 boards with this ISM43362 built-in module

- DISCO_L475VG_IOT01A : https://os.mbed.com/platforms/ST-Discovery-L475E-IOT01A/

- DISCO_F413ZH : https://os.mbed.com/platforms/ST-Discovery-F413H/

Configuration for these boards are known within the driver, no need to update.

For information, file is : wifi-ism43362/mbed_lib.json

mbed-os tests

Wifi tests

Some tests are provided within mbed-os :

- tests-netsocket-tcp/udp/tls/dns

- tests-network-wifi

Test setup

For netsocket tests, you need to configure 1 access point :

  • Internet access
  • SSID name : "wifi-secure-ssid" (SSID can be private)
  • WPA2 password : "wifi-password"

For network-wifi test, you need to configure 2 access points:

  • no need to Internet access
  • SSID name : "wifi-secure-ssid" (SSID has to be broadcasted)
  • WPA2 password : "wifi-password"
  • guest SSID name : "wifi-unsecure-ssid" (SSID has to be broadcasted)
  • channel and the BSSID of secure AP : "wifi-ch-secure", "ap-mac-secure"
  • channel and the BSSID of unsecure AP : "wifi-ch-unsecure", "ap-mac-unsecure"

Test configuration

Now update your mbed_app.json file with :

{
    "config": {
        "echo-server-addr" : {
            "help" : "IP address of echo server",
            "value" : "\"echo.mbedcloudtesting.com\""
        },
        "echo-server-port" : {
            "help" : "Port of echo server",
            "value" : "7"
        },
        "echo-server-discard-port" : {
            "help" : "Discard port of echo server",
            "value" : "9"
        },
        "echo-server-port-tls" : {
            "help" : "Echo port of echo server",
            "value" : "2007"
        },
        "echo-server-discard-port-tls" : {
            "help" : "Discard port of echo server",
            "value" : "2009"
        },
        "wifi-secure-ssid": {
            "help": "WiFi SSID for WPA2 secured network",
            "value": "\"TOREPLACE\""
        },
        "wifi-unsecure-ssid": {
            "help": "WiFi SSID for unsecure network",
            "value": "\"TOREPLACE\""
        },
        "wifi-password": {
            "help": "WiFi Password",
            "value": "\"TOREPLACE\""
        },
        "wifi-secure-protocol": {
            "help": "WiFi security protocol, valid values are WEP, WPA, WPA2, WPA/WPA2",
            "value": "\"WPA2\""
        },
        "wifi-ch-secure": {
            "help": "Channel number of secure SSID",
            "value": 1
        },
        "wifi-ch-unsecure": {
            "help": "Channel number of unsecure SSID",
            "value": 2
        },
        "ap-mac-secure": {
            "help": "BSSID of secure AP in form of AA:BB:CC:DD:EE:FF",
            "value": "\"TOREPLACE\""
        },
        "ap-mac-unsecure": {
            "help": "BSSID of unsecure AP in form of \"AA:BB:CC:DD:EE:FF\"",
            "value": "\"TOREPLACE\""
        },
        "max-scan-size": {
            "help": "How many networks may appear in Wifi scan result",
            "value": 10
        }
   },
    "target_overrides": {
        "DISCO_F413ZH": {
            "target.network-default-interface-type": "WIFI",
            "nsapi.default-wifi-ssid": "\"TOREPLACE\"",
            "nsapi.default-wifi-password": "\"TOREPLACE\"",
            "nsapi.default-wifi-security": "WPA2",
            "ism43362.provide-default": true
        },
        "DISCO_L475VG_IOT01A": {
            "target.network-default-interface-type": "WIFI",
            "nsapi.default-wifi-ssid": "\"TOREPLACE\"",
            "nsapi.default-wifi-password": "\"TOREPLACE\"",
            "nsapi.default-wifi-security": "WPA2",
            "ism43362.provide-default": true
        }
    }
}

You need to update it to indicate your local settings (network SSID, password, ...)

Test execution

mbed test -m DISCO_F413ZH -t ARM -v -n tests-network-wifi
mbed test -m DISCO_L475VG_IOT01A -t GCC_ARM -v -n tests-netsocket-*

WIFI firmware update

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

Instructions will come asap
