# ESP-MQTT sample application

(See the README.md file in the upper level 'examples' directory for more information about examples.)

This example connects to the broker URI selected using `make menuconfig` (using mqtt tcp transport) and as a demonstration subscribes/unsubscribes and send a message on certain topic.
Note: If the URI equals `FROM_STDIN` then the broker address is read from stdin upon application startup (used for testing)

It uses ESP-MQTT library which implements mqtt client to connect to mqtt broker.

## How to use example

### Hardware Required

This example can be executed on any ESP32 board, the only required interface is WiFi and connection to internet.

### Configure the project

```
make menuconfig
```

* Set serial port under Serial Flasher Options.

* Set ssid and password for the board to connect to AP.

### 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.
