- Send messages between Raspberry Pi Pico W's from anywhere using MQTT Broker HiveMQ in MicroPython!
You will only need two or more Raspberry Pi Pico W's with an internet connection!
Library:

This looks like fun. Thanks for the video. Please keep them coming.
Thanks Night Coder, I will do more segments on MQTT eventually! Appreciate that!
How can we handle situations where the MQTT publisher loses internet connection sometimes a day for few hours?
Haha thats a intricate situation you would have to gave the publisher keep trying periodically I would say (programmatically) essentially keeping it running at all times
@@mmshilleh But I wonder how is this problem tackled in real world scenarios. Internet outages can happen suddenly and sometimes it is uncertain, the work goes on and the data is collected but it can't send due to lack of interney
Very nice. I am trying to run a BME280 and SSD1306 together via I2C. I am still working through it (haven't got it to work yet), but it might be something that a lot of other people would find useful as well.
I never played with such screens but I will write this down for a future video. Could be cool to delve into!

Hi i am facing an issue when i install CircuitPython the storage is reducing from 128 mb to 470 kb do you know the reason why it is happening?
BTW it is pico w
Hello Shaik, I used MicroPython for this. I am not sure why it would take a majority of the storage. Do you know the size of the CircuitPython package?
I took your advice and am trying to use mqtt for my controller project. I need some help. How do I buy you a cup of coffee. I'm missing something fundamental. No problem sending stuff to node-red, or back to HiveMQ, but I can't get the messages back to the Pi Pico.
Hey Jack the link is on my youtube page in the links. TH-cam sometimes deletes comments when I link an item in the comments hence why I didnt send it in the chat.

Can you do a video on non blocking tasks. I want two things going at the same time. Read Temp,humidity every 10-15 minutes (post that to MQTT), read distance sensor continuously, turn on LED when distance sensor
I certainly can thanks for bringing this up. I guess before I proceed with that, is the current MQTT framework not sufficient to produce non-blocking tasks or are you having trouble with the coding aspect of it? I would imagine it could be a structure of while loops and timers but I could be naive in the sense that I have not tried to solve the problem or that being an issue for me.
Please elaborate more :)
@@mmshilleh Coding aspect. My MQTT works just fine I was following an example of uasyncio and cannot for the life of me get it to work. Then another video using Time Tics. That one; his Indie accent was too hard for me to follow.
@@mmshilleh They are super cheap. I suppose I could just use 2 Wemos esp8266. 1 for the weather sensor and another for the distance sensor. I'm Just trying to grasp the concept of doing two things at once on one ESP usng micropython.
