# smartconfig Example
This example shows how ESP32 connects to AP with ESPTOUCH. Example does the following steps:
This example shows how ESP32 connects to a target AP with ESPTOUCH.
* Download ESPTOUCH APP from app store. [Android source code](https://github.com/EspressifApp/EsptouchForAndroid) and [iOS source code](https://github.com/EspressifApp/EsptouchForIOS) is available.
## How to use example
* Compile this example and upload it to an ESP32.
### Hardware Required
* Make sure your phone connect to target AP (2.4GHz).
Download ESPTOUCH APP from app store:
[Android source code](https://github.com/EspressifApp/EsptouchForAndroid)
[iOS source code](https://github.com/EspressifApp/EsptouchForIOS) is available.
### Configure the project
```
make menuconfig
```
* Set serial port under Serial Flasher Options.
### Build and Flash
Build the project and flash it to the board, then run monitor tool to view serial output:
```
make -j4 flash monitor
```
(To exit the serial monitor, type ``Ctrl-]``.)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
## Example output
* Make sure your phone connect to the target AP (2.4GHz).
* Open ESPTOUCH app and input password. There will be success message after few sec.
### Example output
Here is an example of smartconfig console output.
```
I (372) wifi: mode : sta (24:0a:c4:00:44:86)
