# MQTT Subscriber and Sender Example
Here's an example for MQTT subscriber and sender.
## Introduction
The MQTT protocol is very simple, which is very suitable for IoT devices with limited processor resources and limited network bandwidth.
## Requirements
- paho-mqtt
## Usage
First, make a subscriber.
You can change the topics and MQTT server address(a.k.a MQTT Broker) in the program.
The default is official server `test.mosquitto.org` with default port `1883`.
```bash
python3 example_subscriber.py
```
And, we can try sender(a.k.a publisher) to send messages.
The messages can be any format like `JSON`, `list`, `Numpy Array` and so on cause `Sender` will change the data you send to be **binary object** in the backend by using pickle package.
When the message is sent, all users with subscription related items can receive the message.
```bash
python3 example_sender.py
```
## Result
* Subscriber
```
Connected with result code 0
yee {'test1': 1234, 'test2': 'yee'}
yoo 1234
yoo b'ABCDEFG'
yoo ['1', 'a', 'b']
```
