# mDNS example
Shows how to use mDNS to advertise lookup services and hosts
## Example workflow
- mDNS is initialized with host name and instance name defined through the project configuration and `_http._tcp` service is added to be advertised
- WiFi STA is started and trying to connect to the access point defined through the project configuration
- The system event handler is used to pass the network events to mDNS so the service is aware when the interface comes up or down
- GPIO0 (BOOT Button) is initialized as pulled-up input that can be monitored for button press
- Example task is started to check if the button is pressed so it can execute the mDNS queries defined
### Configure the project
* Open the project configuration menu (`idf.py menuconfig`)
* Configure Wi-Fi or Ethernet under "Example Connection Configuration" menu. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../README.md) for more details.
* When using Make build system, set `Default serial port` under `Serial flasher config`.
* Set `mDNS Hostname` as host name prefix for the device and its instance name in `mDNS Instance Name`
* Disable `Resolve test services` to prevent the example from querying defined names/services on startup (cause warnings in example logs, as illustrated below)
### Build and Flash
Build the project and flash it to the board, then run monitor tool to view serial output:
```
idf.py -p PORT flash monitor
```
- Wait for WiFi to connect to your access point
- You can now ping the device at `[board-hostname].local`, where `[board-hostname]` is preconfigured hostname, `esp32-mdns` by default.
- You can also browse for `_http._tcp` on the same network to find the advertised service
- Pressing the BOOT button will start querying the local network for the predefined in `check_button` hosts and services
- Note that for purpose of CI tests, configuration options of `MDNS_RESOLVE_TEST_SERVICES` and `MDNS_ADD_MAC_TO_HOSTNAME` are available, but disabled by default. If enabled, then the hostname suffix of last 3 bytes from device MAC address is added, e.g. `esp32-mdns-80FFFF`, and a query for test service is issued.
(To exit the serial monitor, type ``Ctrl-]``.)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
