+
+Wi-Fi example for Mbed OS
+
+## Getting started with the Wi-Fi API ##
+
+This is an example of a Wi-Fi application using the Wi-Fi and network socket APIs that [Mbed OS](https://github.com/ARMmbed/mbed-os) provides.
+
+The program brings up the Wi-Fi and the underlying network interface and uses it to scan available networks, connects to a network, prints interface and connection details and performs an HTTP operation.
+
+For more information about Wi-Fi APIs, please visit the [Mbed OS Wi-Fi](https://os.mbed.com/docs/latest/reference/wi-fi.html) documentation.
+
+### Supported hardware ###
+
+* [NUCLEO-F401RE](https://os.mbed.com/platforms/ST-Nucleo-F401RE/) with [X-NUCLEO-IDW04A1](http://www.st.com/content/st_com/en/products/ecosystems/stm32-open-development-environment/stm32-nucleo-expansion-boards/stm32-ode-connect-hw/x-nucleo-idw04a1.html) Wi-Fi expansion board using pins D8 and D2 _(of the Arduino connector)_.
+* [NUCLEO-F401RE](https://os.mbed.com/platforms/ST-Nucleo-F401RE/) with [X-NUCLEO-IDW01M1](https://os.mbed.com/components/X-NUCLEO-IDW01M1/) Wi-Fi expansion board using pins PA_9 and PA_10 _(of the Morpho connector)_.
+* [DISCO_L475VG_IOT01A](https://os.mbed.com/platforms/ST-Discovery-L475E-IOT01A/) with ISM43362 built-in module
+* [DISCO_F413ZH](https://os.mbed.com/platforms/ST-Discovery-F413H/) with ISM43362 built-in module
+* Other Mbed targets with  [X-NUCLEO-IDW04A1](http://www.st.com/content/st_com/en/products/ecosystems/stm32-open-development-environment/stm32-nucleo-expansion-boards/stm32-ode-connect-hw/x-nucleo-idw04a1.html) or [X-NUCLEO-IDW01M1](https://os.mbed.com/components/X-NUCLEO-IDW01M1/) expansion board.
+  *(The Mbed target board the Wi-Fi shield connects to shouldn't have any other network interface, for example Ethernet.)*
+
+#### Connecting the X-NUCLEO-IDW0XX1 ####
+
+To connect the [X-NUCLEO-IDW04A1](http://www.st.com/content/st_com/en/products/ecosystems/stm32-open-development-environment/stm32-nucleo-expansion-boards/stm32-ode-connect-hw/x-nucleo-idw04a1.html) or [X-NUCLEO-IDW01M1](https://developer.mbed.org/components/X-NUCLEO-IDW01M1/) expansion board to your NUCLEO development board, plug the expansion board on top of the NUCLEO board using the Arduino or Morpho connector.
+
+##  Getting started ##
+
+1. Import the example.
+
+   ```
+   mbed import mbed-os-example-wifi
+   cd mbed-os-example-wifi
+   ```
+   
+2. Configure the Wi-Fi shield to use.
+
+   Edit ```mbed_app.json``` to include the correct Wi-Fi shield, SSID and password:
+
+   ```
+       "config": {
+ 	  "wifi-shield": {
+               "help": "Options are WIFI_IDW0XX1",
+               "value": "WIFI_IDW0XX1"
+        	  },
+           "wifi-ssid": {
+               "help": "WiFi SSID",
+               "value": "\"SSID\""
+           },
+           "wifi-password": {
+               "help": "WiFi Password",
+               "value": "\"Password\""
+           }
+       },
+   ```
+
+   Sample ```mbed_app.json``` files are provided for X-NUCLEO-IDW04A1 (```mbed_app_idw04a1.json```),  X-NUCLEO-IDW01M1 (```mbed_app_idw01m1```), DISCO_L475VG_IOT01A/ISM43362 (```mbed_app_ism43362.json```) and DISCO_F413ZH/ISM43362 (```mbed_app_ism43362.json```)
+   
+   For built-in Wi-Fi, ignore the value of `wifi-shield`.
+
+3. Compile and generate binary.
+
+   For example, for `GCC`:
+
+   ```
+   mbed compile -t GCC_ARM -m UBLOX_EVK_ODIN_W2
+   ```
+   
+ 4. Open a serial console session with the target platform using the following parameters:
+ 
+    * **Baud rate:** 9600
+    * **Data bits:** 8
+    * **Stop bits:** 1
+    * **Parity:** None
+ 
+ 5. Copy or drag the application `mbed-os-example-wifi.bin` in the folder `mbed-os-example-wifi/BUILD/<TARGET NAME>/<PLATFORM NAME>` onto the target board.
+ 
+ 6. The serial console should display a similar output to below, indicating a successful Wi-Fi connection:
+ 
+ ```
