mbed_official | 0:857719181846 | 3 | WiFi example for mbed OS |
mbed_official | 0:857719181846 | 4 | |
mbed_official | 0:857719181846 | 5 | ## Getting started with the WiFi API ## |
mbed_official | 0:857719181846 | 6 | |
mbed_official | 0:857719181846 | 7 | This is a quick example of a simple WiFi application using the WiFi and network-socket APIs that is provided as a part of [mbed-os](github.com/armmbed/mbed-os). |
mbed_official | 0:857719181846 | 8 | |
mbed_official | 0:857719181846 | 9 | The program brings up the WiFi and the underlying network interface, and uses it to scans available networks, connects to a network, prints interface and connection details and performs simple HTTP operation. |
mbed_official | 0:857719181846 | 10 | |
mbed_official | 0:857719181846 | 11 | ### Supported hardware ### |
mbed_official | 0:857719181846 | 12 | |
mbed_official | 22:887649aaedcb | 13 | * [UBLOX Odin board](https://developer.mbed.org/platforms/ublox-EVK-ODIN-W2/) built-in WiFi module |
mbed_official | 22:887649aaedcb | 14 | * [REALTEK_RTL8195AM](https://developer.mbed.org/platforms/REALTEK-RTL8195AM/) built-in WiFi module |
mbed_official | 32:bca3f5f442b3 | 15 | * [NUCLEO_F401RE](https://developer.mbed.org/platforms/ST-Nucleo-F401RE/) with [X-NUCLEO-IDW01M1](https://developer.mbed.org/components/X-NUCLEO-IDW01M1/) WiFi expansion board using pins D8 D2 |
mbed_official | 10:5b5beb106156 | 16 | * [NUCLEO_F429ZI](https://developer.mbed.org/platforms/ST-Nucleo-F429ZI/) with ESP8266-01 module using pins D1 D0 |
mbed_official | 10:5b5beb106156 | 17 | * [NUCLEO_L476RG](https://developer.mbed.org/platforms/ST-Nucleo-L476RG/) with ESP8266-01 module using pins D8 D2 |
mbed_official | 32:bca3f5f442b3 | 18 | * Other mbed targets with ESP8266 module or [X-NUCLEO-IDW01M1](https://developer.mbed.org/components/X-NUCLEO-IDW01M1/) expansion board |
mbed_official | 32:bca3f5f442b3 | 19 | *(the mbed target board the WiFi shield gets connected to shouldn't have any other network interface e.g. Ethernet)* |
mbed_official | 0:857719181846 | 20 | |
mbed_official | 32:bca3f5f442b3 | 21 | ESP8266 is a fallback option and will be used if the build is for unsupported platform. |
mbed_official | 0:857719181846 | 22 | |
mbed_official | 32:bca3f5f442b3 | 23 | #### Connecting the ESP8266 #### |
mbed_official | 27:b3c6dba3b6e9 | 24 | 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 | 25 | |
mbed_official | 32:bca3f5f442b3 | 26 | **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 | 27 | |
mbed_official | 32:bca3f5f442b3 | 28 | #### Connecting the X-NUCLEO-IDW01M1 #### |
mbed_official | 32:bca3f5f442b3 | 29 | To connect the [X-NUCLEO-IDW01M1](https://developer.mbed.org/components/X-NUCLEO-IDW01M1/) expansion board to your NUCLEO development board, just plug the expansion board on top of the NUCLEO board using the Morpho connector. |
