mbed_official 49:d44cac40bf15 3 Wi-Fi example for Mbed OS
mbed_official 0:857719181846 4
mbed_official 49:d44cac40bf15 5 ## Getting started with the Wi-Fi API ##
mbed_official 0:857719181846 6
mbed_official 49:d44cac40bf15 7 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.
mbed_official 0:857719181846 8
mbed_official 49:d44cac40bf15 9 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.
mbed_official 49:d44cac40bf15 10
mbed_official 49:d44cac40bf15 11 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.

mbed_official 77:b74ac6641a3e 30 #### Adding connectivity driver
mbed_official 77:b74ac6641a3e 31
mbed_official 77:b74ac6641a3e 32 If the target does not have internal WiFi driver, or Mbed OS does not supply one, you need to add driver to your application and configure it to provide default WiFi interface.
mbed_official 77:b74ac6641a3e 33
mbed_official 77:b74ac6641a3e 34 ```
mbed_official 77:b74ac6641a3e 35 mbed add <driver>
mbed_official 77:b74ac6641a3e 36 ```
mbed_official 77:b74ac6641a3e 37
mbed_official 82:122bb3ae6de5 38 For example adding ISM43362 driver `mbed add wifi-ism43362` or ESP8266 `mbed add esp8266-driver` or X-Nucleo-IDW01M1 driver `mbed add wifi-x-nucleo-idw01m1`
mbed_official 77:b74ac6641a3e 39
mbed_official 77:b74ac6641a3e 40 Then pin names need to be configured as instructed in the drivers README file.
mbed_official 77:b74ac6641a3e 41
mbed_official 32:bca3f5f442b3 42 #### Connecting the ESP8266 ####
mbed_official 49:d44cac40bf15 43
mbed_official 27:b3c6dba3b6e9 44 To connect the ESP8266 module to your development board, look at the [ESP8266 Cookbook page](https://developer.mbed.org/users/4180_1/notebook/using-the-esp8266-with-the-mbed-lpc1768/). In general, this means hooking up the ESP8266 TX pin to `D0` and the ESP8266 RX pin to `D1` on your development board.
mbed_official 6:9944c5308062 45
mbed_official 49:d44cac40bf15 46 **Note:** On NUCLEO development boards, pins `D0` and `D1` are used for serial communication with the computer. Use pins `D8` (to ESP8266 TX) and `D2` (to ESP8266 RX) instead.
mbed_official 32:bca3f5f442b3 47
mbed_official 44:63be19b7a3db 48 #### Connecting the X-NUCLEO-IDW0XX1 ####
mbed_official 49:d44cac40bf15 49
mbed_official 49:d44cac40bf15 50 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.
mbed_official 6:9944c5308062 51
mbed_official 44:63be19b7a3db 52 ## Getting started ##
mbed_official 0:857719181846 53
mbed_official 49:d44cac40bf15 54 1. Import the example.
mbed_official 0:857719181846 55
mbed_official 32:bca3f5f442b3 56 ```
mbed_official 32:bca3f5f442b3 57 mbed import mbed-os-example-wifi
mbed_official 32:bca3f5f442b3 58 cd mbed-os-example-wifi
mbed_official 32:bca3f5f442b3 59 ```
mbed_official 71:a0fbcc153b55 60
mbed_official 82:122bb3ae6de5 61 1. Configure the Wi-Fi shield and settings.
mbed_official 49:d44cac40bf15 62 Edit ```mbed_app.json``` to include the correct Wi-Fi shield, SSID and password:
mbed_official 0:857719181846 63
mbed_official 86:92e4be20dc8b 64 ```json
mbed_official 82:122bb3ae6de5 65 {
mbed_official 82:122bb3ae6de5 66 "config": {
mbed_official 82:122bb3ae6de5 67 "wifi-ssid": {
mbed_official 82:122bb3ae6de5 68 "help": "WiFi SSID",
mbed_official 82:122bb3ae6de5 69 "value": "\"SSID\""
mbed_official 82:122bb3ae6de5 70 },
mbed_official 82:122bb3ae6de5 71 "wifi-password": {
mbed_official 82:122bb3ae6de5 72 "help": "WiFi Password",
mbed_official 82:122bb3ae6de5 73 "value": "\"PASSWORD\""
mbed_official 82:122bb3ae6de5 74 }
mbed_official 82:122bb3ae6de5 75 },
mbed_official 82:122bb3ae6de5 76 "target_overrides": {
mbed_official 82:122bb3ae6de5 77 "*": {
mbed_official 82:122bb3ae6de5 78 "platform.stdio-convert-newlines": true,
mbed_official 82:122bb3ae6de5 79 "esp8266.provide-default" : false
mbed_official 82:122bb3ae6de5 80 }
mbed_official 82:122bb3ae6de5 81 }
mbed_official 82:122bb3ae6de5 82 }
mbed_official 86:92e4be20dc8b 83 ```
mbed_official 0:857719181846 84
mbed_official 82:122bb3ae6de5 85 For build-in WiFi, you do not need to set any `provide-default` values. Those are required
mbed_official 82:122bb3ae6de5 86 if you use external WiFi shield.
mbed_official 82:122bb3ae6de5 87
mbed_official 49:d44cac40bf15 88 Sample ```mbed_app.json``` files are provided for ESP8266 (```mbed_app_esp8266.json```), X-NUCLEO-IDW04A1 (```mbed_app_idw04a1.json```) and X-NUCLEO-IDW01M1 (```mbed_app_idw01m1```).
mbed_official 71:a0fbcc153b55 89
mbed_official 33:12f0df4d51d7 90
mbed_official 71:a0fbcc153b55 91 1. Compile and generate binary.
mbed_official 71:a0fbcc153b55 92 For example, for `GCC`:
mbed_official 71:a0fbcc153b55 93 ```
mbed_official 71:a0fbcc153b55 94 mbed compile -t GCC_ARM -m UBLOX_EVK_ODIN_W2
mbed_official 71:a0fbcc153b55 95 ```
mbed_official 32:bca3f5f442b3 96
mbed_official 71:a0fbcc153b55 97 1. Open a serial console session with the target platform using the following parameters:
mbed_official 36:aa0b6789bbd2 98 * **Baud rate:** 9600
mbed_official 36:aa0b6789bbd2 99 * **Data bits:** 8
mbed_official 36:aa0b6789bbd2 100 * **Stop bits:** 1
mbed_official 36:aa0b6789bbd2 101 * **Parity:** None
mbed_official 71:a0fbcc153b55 102
mbed_official 71:a0fbcc153b55 103 1. 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.
mbed_official 36:aa0b6789bbd2 104
mbed_official 71:a0fbcc153b55 105 1. The serial console should display a similar output to below, indicating a successful Wi-Fi connection:
