Getting Started with MQTT on Arduino Using ESP8266

Watch this video to learn how to use the Arduino IDE to program an ESP8266 microcontroller for reading sensor data and publishing it using MQTT to a HiveMQ Cloud MQTT broker.
Additionally, see how to receive MQTT messages as commands from the cloud and activate the microcontroller output to switch ON and OFF a Light Emitting Diode (LED).

How you created this certificate, can u pls explain i a bit confused

[Godsbeloved]

Great explanations but how do you get the root ca, tried everything but cant get it

[josedanielmartinez]

Thanks, could it be possible to get the code?? And how can i get the root certificate?

[adelsonauzier]

HI. Great Job. Can you explain the conditional compiling in the lines 150 to 154? setInsecure() is mandatory? I'm confused with this comand at now. I have a trouble with the function setCACert( ), IDE talks: Compilation error: 'class BearSSL::WiFiClientSecure' has no member named 'setCACert'

Thanks but it's not working

Connecting to MQTT Broker as
Failed to connect to MQTT broker, rc=-2 try again in 5 seconds

I'm guessing I could use a MQTT broker on my home server and send publish messages from Home Assistant (not really sure, I'm still a noob).... Would be awesome to build some totally custom stuff. You've showed me the path forward, thank you for a good video.

There is a 10 GB data limit in your free plan. So, is there a data upload speed limit in this plan? Can I upload data at 500 kbps with ESP32?

[GurgelBR]

Where Can I obtain the certificate? (time reference of video: 9:08)

[ArdyAryan]

where do we get the certificate?
Thanks

[SravyaTaduthuri]

thanku sir... can you please make a video on connecting to mqtt broker on stm32cube ide using esp8266

[batirniyazmatov]

for esp32 how can I connect. there is a video tutorial for esp32

[Lachlan.Wright]

Love your videos man. I am curious if yoy can get Sparkplugb on Arduino. Eg on an Opta?

[shreyasstuffbits]

bro you didn't explained how to setup MQTT Fx

[trinhquocphong]

Can you share your Arduino code? Thank you.

What a bad video, only shown code like a grad student and no explanation about how to get CA, why do need randomised client id etc
