DISCO-L475VG-IOT01A and HTTP EXAMPLE

Mbed OS
1

Can anyone help me to get the DISCO-L475VG-IOT01A working with the HTTP EXAMPLE,

README.md file does say’

Tested on DISCO-L475VG-IOT01A with WiFi (requires the wifi-ism43362 driver).

So someone at Mbed must have got it working.

I’m using the online compiler.

I have added the st wi-fi driver to the root of the HTTP EXAMPLE folder,

This is my mbed_app.json file,

        "wifi-dataready": "PG_12",
        "wifi-wakeup": "PB_15"
    }
}

}

I have also added this to network-helper.h file,

#include "ISM43362Interface.h"
ISM43362Interface wifi(MBED_CONF_APP_WIFI_SPI_MOSI, MBED_CONF_APP_WIFI_SPI_MISO, MBED_CONF_APP_WIFI_SPI_SCLK, MBED_CONF_APP_WIFI_SPI_NSS, MBED_CONF_APP_WIFI_RESET, MBED_CONF_APP_WIFI_DATAREADY, MBED_CONF_APP_WIFI_WAKEUP, false);

But still get this when trying to connect,

[NWKH] No network interface found, select an interface in ‘network-helper.h’
Cannot connect to the network, see serial output

No build errors or warnings and have tried many different combinations.
Its going to be really simple, but I can’t get there.
The example works fine on many other platforms using the Mbed ESP8266 wi-fi.
Any suggestions would be appreciated.

I also have problems with examples mentioned by the mbed-http repo. It seem that latest mbed-os, may be after 5.11, may break mbed-http library. BTW, my WiFi works with the following mbed_app.json.

{
    "config": {
        "wifi-ssid": {
            "help": "WiFi SSID",
            "value": "\"SSID\""
        },
        "wifi-password": {
            "help": "WiFi Password",
            "value": "\"PASSWORD\""
        }        
    },
    "target_overrides": {
        "*": {
            "platform.stdio-convert-newlines": true     
        },
        "DISCO_L475VG_IOT01A": {
            "ism43362.provide-default": true
        }
    }
}

For the code, I have used the following code.

WiFiInterface* wifi = WiFiInterface::get_default_instance();
