# Hello World Example
Starts a FreeRTOS task to print "Hello World".
# Wi-Fi Station Example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example shows how to use the Wi-Fi Station functionality of the Wi-Fi driver of ESP for connecting to an Access Point.
## How to use example
Follow detailed instructions provided specifically for this example.
### Configure the project
Select the instructions depending on Espressif chip installed on your development board:
Open the project configuration menu (`idf.py menuconfig`).
- [ESP32 Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/stable/get-started/index.html)
- [ESP32-S2 Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/get-started/index.html)
In the `Example Configuration` menu:
* Set the Wi-Fi configuration.
* Set `WiFi SSID`.
* Set `WiFi Password`.
## Example folder contents
Optional: If you need, change the other options according to your requirements.
The project **hello_world** contains one source file in C language [hello_world_main.c](main/hello_world_main.c). The file is located in folder [main](main).
### Build and Flash
ESP-IDF projects are built using CMake. The project build configuration is contained in `CMakeLists.txt` files that provide set of directives and instructions describing the project's source files and targets (executable, library, or both).
Build the project and flash it to the board, then run the monitor tool to view the serial output:
Below is short explanation of remaining files in the project folder.
Run `idf.py -p PORT flash monitor` to build, flash and monitor the project.
(To exit the serial monitor, type ``Ctrl-]``.)
See the Getting Started Guide for all the steps to configure and use the ESP-IDF to build projects.
* [ESP-IDF Getting Started Guide on ESP32](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html)
* [ESP-IDF Getting Started Guide on ESP32-S2](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/get-started/index.html)
* [ESP-IDF Getting Started Guide on ESP32-C3](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/get-started/index.html)
## Example Output
Note that the output, in particular the order of the output, may vary depending on the environment.
Console output if station connects to AP successfully:

## Running the example on ESP Chips without Wi-Fi
This example can run on ESP Chips without Wi-Fi using ESP-Hosted. See the [Two-Chip Solution](../../README.md#wi-fi-examples-with-two-chip-solution) section in the upper level `README.md` for information.
## Troubleshooting
* Program upload failure
* Hardware connection is not correct: run `idf.py -p PORT monitor`, and reboot your board to see if there are any output logs.
* The baud rate for downloading is too high: lower your baud rate in the `menuconfig` menu, and try again.
## Technical support and feedback
Please use the following feedback channels:
* For technical queries, go to the [esp32.com](https://esp32.com/) forum
* For a feature request or bug report, create a [GitHub issue](https://github.com/espressif/esp-idf/issues)
We will get back to you as soon as possible.
For any technical queries, please open an [issue](https://github.com/espressif/esp-idf/issues) on GitHub. We will get back to you soon.
