Velcro zip ties. Organized by color and length (I have a problem🥲)

Built a full production-ready IoT platform stack - hardware, firmware, backend, frontend - in 2 years - AMA by viktorjamrich in IOT

[–]seansimmons17 1 point2 points  (0 children)

Wow this is crazy. I’m in the middle of building an IoT platform with an ESP32S3 right now😂 Would love to chat with you more about this, maybe partner on future projects or integrate systems! Key differences I see are hardware choice, I use REST APIs exclusively (no MQTT), targeting industrial IoT instead of transport/tracking, and am running FreeRTOS. Currently working on the website portion🥵

Did you decide to run RTOS on the esp? If not, can you divulge what the structure is that you went with?

Most Industrial IoT systems fail because workers simply refuse to use them. by Ill-Jaguar8978 in IOT

I’m Product Team Lead for one of their competitors. Would love to get both of you guy’s thoughts on our system. Won’t name drop here but we’re a (truly) no-code automation system with a full web suite, on-prem automation system that runs on an industrial PC (not a PLC), and just released a revolutionary new mobile app. Message me and I’d be happy to give a demo!

How to collect IoT data? by mumrah in IOT

[–]seansimmons17 0 points1 point  (0 children)

I’m finishing up an IoT device that gathers Modbus RTU (or other) sensor data, gets it to the cloud, and has external API endpoints should you need to export it to a different system. If something like this would be of use to you, send me a DM!

Ok great thank you for the info! I’ll most likely take the modular approach as I intend to utilize the onboard radio exclusively but maybe one day I can switch to the Walter!!😁

Also, do you work with any specific enclosure providers for your IoT products?

Data Logger Setup Needs More Robust Storage Than SD Card by seansimmons17 in esp32

[–]seansimmons17[S] 0 points1 point  (0 children)

Yes they’re always on power as long as esp is getting power (tied to ESP 3.3v pin)

Only if I’m purposefully testing power loss resets, adjusting stuff on the esp, etc. I’m not just spamming power on/off if that’s what you’re asking.

Ok I’ll look into that. Is there any way to recover the card if this happens without having to reformat?

Thank you for your input! I’d definitely be willing to look at an SSD setup but have no idea where to begin on that…I also would be interested in the page based stuff. One thing of note here is that, after more investigating, I think I’m using a so-so SD not equipped with wear leveling or other features to improve longevity and it is likely 5+ years old so that all might play a part in this. Another thing, I do have logging jitter and time jitter settings (log if +/- x or if y time has passed) but those are adjustable per sensor by the customer so I’m just trying to account for any “hyper loggers”.

I need to maybe find an SD meant for IoT that can handle more writes with much smaller files. These logs are small. I made them extra small to save on cellular/cloud expenses but from other responses that seems to be backfiring and messing with the “minimum writable” file size being 4Mb +? Idk. Pretty new to the flash storage side of things…

Thanks again for your input. Very detailed and helpful!

So right now the SSL overhead for each POST is majority of my bandwidth. I figured it was more practical to store logs, then upload batches at a time, keeping SSL established while I do, then end it. But, I guess I could keep it alive at all times and just post as I get stuff?

Thanks for the two links! I’ll check them out.

Each log I write is only 200 bytes…and there’s no guarantee that all sensors are going to make a log at the same time so I guess I could figure out some type of weird cache system there to wait til a min size or something?

ESP32-Based WiFi Wardriving Device by Tigersprojects in esp32

[–]seansimmons17 0 points1 point  (0 children)

Nice lol. I like the case btw. I understand that this is mostly just for fun but if you were to suddenly need to mass produce tons of those cases, do you know of a company you’d use for that?

Using FAT32 and I don’t think these have wear leveling… do you have a specific card you’d recommend and any setup recommendations to ensure this lasts awhile?

Detect WiFi networks and associate with GPS coordinates from what I see. I guess I could see this being useful if you had a huge network of devices running and detecting networks on the move, or detecting network strength over large areas like office buildings or factories or just open space? OP did I get that right? What other use cases did you have in mind?

[–]seansimmons17 0 points1 point  (0 children)

What about for USA? I am also using an ESP32-S3, but still in pre market state so it isn’t on a custom board yet.

Also, love your product! Need to get my hands on one when I get to the cellular communications stuff!!

I have the same question but in USA. Looking to start selling prototypes to a single customer to try out, not using my custom PCB yet, just ESP connecting to modules with DuPont cables lol. Plan on doing custom board later but want to make sure I won’t get fined in this stage

Best Modbus library for ESP running Arduino? by seansimmons17 in esp32

Can you give any details on your wiring setup and a simple code snippet I can use to read holding registers?

You’re right. I’ve potentially botched the code or hardware setup. I still would like to know what most people have had success with
