Okay thanks.

I'm Rémi I come from France

Currently I'm working on trains (the software part) and in my free time I'm working on a slam robotics project

RémiOP•3/29/24, 7:47 PM

I'm working mainly with c/c++

RémiOP•3/29/24, 7:47 PM

Before all that I was web developer

RémiOP•3/29/24, 7:47 PM

For about 3 years

Thanks

RémiOP•3/29/24, 7:49 PM

I'm happy to be here

RémiOP•3/29/24, 7:50 PM

It's the first embedded systems community I found on discord

RémiOP•3/29/24, 7:50 PM

It's nice to have somewhere to talk about all of this

nour_oud•3/29/24, 7:55 PM

You are in the right place, if you have any questions, do not hesitate to ask them here or in the forums:

skarif•3/30/24, 2:39 PM

Hiii @techielew i got into Embedded Ai and working as a research Engineer. Seeking to explore deeper into hard core Embedded systems. If anyof you can suggest a clear roadmap it will be highly appreciated. Thanks

Ttechielew @Umesh Lokhande dyk?

Umesh Lokhande•3/30/24, 2:40 PM

Usually, MQTT protocol allows the payload size of up to 256 MB. But always recommended to check with the broker documentation to ensure if there is any limit from mqtt broker s/w side. I don't think the size has to do with MCU either ESP32 or any other

Publishing an important size of data we'll block the cpu or just pass data to the tcp/ip stack and initiate tye transfer and do something else ?

Umesh Lokhande•3/30/24, 2:57 PM

I'd prefer asynchronous handling of data using buffer and then let the CPU handle other tasks. In this case, data transfer will be hapenning in the background so the CPU is free to complete other tasks

@Middleware & OS any micropython users in server? We’re discussing C, Rust, Python/micropython on next week’s Office Hours and would love the additional perspective? I know @abhishek awasthi is a Python user, @barafael is a rust lover, and everyone better know some C/C++

(hopefully @kmulier will be able to join and lend some perspectives).

If you’d like to address any other languages lmk but really curious if there’s a micropython power user in the house!

Thank you Ben but I'm searching for one that can be cut by cnc, cuz 3d printing is not available, do you have any other ideas?

techielew•3/30/24, 3:32 PM

That’s great do you want to join OH on Friday and lend some of your experience to the discussion?

Camila_99$$•3/30/24, 3:43 PM

Hi! Has anyone already used the MQTT protocol with an ESP32 for external access to the local network? Is there any documentation available to set up such a system or a tutorial?

Camila_99$$•3/30/24, 3:45 PM

I could also consider a solution via Firebase, but I don't know how to connect multiple ESPs to the same real-time database and segment the data by ESP connecting to the database.

Yes, I'll be covering how to control devices connected to ESP32 from anywhere using the public server and MQTT Protocol.

Umesh Lokhande•3/30/24, 3:55 PM

There are many ways you can make this happen. My preferred approach will be using MEAN/MEARN stack where MongoDB will be used as a database to store realtime data on MQTT server. I have not used firebase. But handled these scenarios very often.

I'm using my own broker on Digital Ocean with NodeJs for backent and Mysql as database and React for front end, but as @Umesh Lokhande told mern is the beetter way but you have to do any thing by your self
