00:00Hi everyone and welcome. In this video we will see how to set up MQTT broker in

00:07Xiao ESP32C3 using embedded MQTT broker library. So if you want to use

00:13your Xiao ESP32C3 board as a MQTT broker then you can use it using

00:18embedded MQTT broker library. So instead of using Mosquito MQTT broker or

00:23Hive MQTT broker or EMQX broker, Nano MQTT broker you can use tiny little Xiao

00:31ESP32C3 board as a MQTT broker and you can place in your local area network

00:36and your MQTT client can exchange the data using this Xiao ESP32C3 MQTT

00:42broker. So let's see how you can create MQTT broker using Xiao ESP32C3.

00:48So I have ESP32C3 connected with my system and here is the Arduino IDE.

00:54Before uploading the code here is the connection diagram. So our ESP32C3

01:00board is in the center which will act as a MQTT broker and different

01:04different MQTT client can connect with this Xiao ESP32C3 MQTT broker and they

01:09can exchange the data. Now every client can publish and subscribe to any topic

01:15that is also possible and everything will be work in the local area network.

01:19So if you have multiple devices in your local area network then you can exchange

01:23the data. If you want to control some LED in your local area network then

01:28also you can do that. If you want to read some sensor data from anywhere in the

01:32local area network to your mobile phone to your dashboard then also you can do

01:36that. So all these options are possible with the embedded MQTT broker library. So

01:42here is our Arduino and I have already installed the embedded MQTT broker

01:46library. So I'm going to copy this and here we will search it. OK. Here you can

01:51see it is already installed in my Arduino IDE. You can also install and

01:55then you can use it. Now once you install this embedded MQTT broker

01:59library you have to go to the examples. OK. And here you have to search for the

02:05embedded MQTT broker folder and here it is. OK. Embedded MQTT broker and here we

02:11have the two example HTTP server and MQTT broker and another example is

02:16simple MQTT broker. Now I'm going to use this simple MQTT broker sketch to use

02:21my ESP32C3 as MQTT broker. OK. So here is our sketch. So first of all what you

02:29have to do is you have to provide your Wi-Fi SSID and password to connect your

02:34Xiao ESP32C3 with your Wi-Fi. OK. Or you can say to put your ESP32C3 in the

02:41local area networks. So here I'm going to provide the SSID and password of my

02:45Wi-Fi. So. OK. So here is the SSID and the password of my Wi-Fi. So our ESP32C3

02:54will connect with our Wi-Fi. OK. And it will act as an MQTT broker. So all of the

02:59MQTT client can use our ESP32C3 MQTT broker and they can exchange the

03:04data. OK. And then after here you can see in this line you have to specify that on

03:10which TCP port you want to start your MQTT broker. So right now the default

03:15port is 1883. OK. But if you want to change the TCP port for your MQTT

03:19broker then you can change it from here. OK. And you can leave the rest of the

03:24thing as it is and you can directly upload this code into your ESP32C3

03:29board. So here is my ESP32C3 connected. I'm going to upload this sketch

03:34into my ESP32C3 board.

03:40OK. So our sketch is successfully uploaded to the ESP32C3 board and now we can open

03:59the serial monitor.

04:02Let me press the reset button. OK. OK. Here you can see Wi-Fi connected. Broker

04:09started and the broker is running on this IP address 192.168.1.2 and the port

04:15is 1883. OK. So we can use this IP address and we can use this port number to

04:20connect with the MQTT broker running inside our ESP32C3 board. So I can open

04:26my MQTT Explorer software. OK. And I can provide the IP address which is 192.168.1.2

04:34OK. I am going to create one more connection and it's our ESP32C3. OK. I'm

04:43going to save it. The port number is 1883 and we can click on connect. OK. You can

04:51see it is connected. Now we can open one more MQTT client. OK. Which is MQTT

04:56Explorer and I'm going to use the same IP address and port number to connect

05:01with my ESP32C3 MQTT broker. But I'm not going to use the same client ID. So

05:09here you can see MQTT client ID. So I'm going to change my client ID and then we

05:13will go back and then we will connect. OK. So we are connected with our ESP32C3

05:18MQTT broker and in the topic I'm going to publish some values on the test

05:24topic. So topic is test. The value is 1 2 3. OK. And I'm going to publish it. And

05:30here you can see we have received the value in another client. Also I can

05:34update the same topic value from different clients. So 4 5 6 and I can

05:41publish. And here you can see we have received the value. OK. So this is how

05:47you can use your ESP32C3 board as a MQTT broker. So multiple client can

05:52connect with your ESP32C3 board and they can exchange the data. And your

05:56client can be your Python client, your Node-RED, your SCADA system, your

06:00Raspberry Pi. OK. Or any other ESP32C3 board or any other ESP32 board or

06:06NodeMCU board anything. So you can use this ESP32C3 as a MQTT broker. Instead

06:12of using Raspberry Pi and installing another MQTT broker in the Raspberry Pi

06:16you can use this tiny and low cost microcontroller to create your own MQTT

06:21broker. Also you can do the port forwarding and you can use this ESP32C3

06:26MQTT broker as a cloud MQTT broker as well. OK. But with the help of port

06:30forwarding. So you have to learn that how to do the port forwarding for your ESP32C3

06:35board. So I hope this thing is clear that how you can set up MQTT

06:40broker in the Xiao ESP32C3 board. And if you still have any questions or any

06:46doubt then you can always ping me on Telegram, Instagram, WhatsApp, anywhere.

06:49And if you want to know more about the embedded MQTT broker library then here I

06:53have provided the GitHub repository link for this library. You can go and you can

06:56check out the limitations and everything. OK. So I hope everything is clear and if

07:01you still have any questions or any doubt then you can always ping me on Telegram,

07:04Instagram, WhatsApp. All the social media link is available on our website. So

07:09let's meet in the future videos. OK. Till then take care. Goodbye and thank you.
