LoRa or WiFi Client-Server Library (Help and/or Interest)

@inq 7

Hi @inq,

   Sorry, I don't presently have any great ambitions as an end-user about a general purpose IoT station, but curiosity etc. will almost certainly mean I will be at least at casual observer level, probably more interested in technology (soft, hard or whatever) bits that are different or unusual, especially if they are relevant in other spheres.

I'm reluctant to take on open-ended commitments but obviously, if something piques my interest, I'll see what I can do, and if requested, may be willing to help out on specific bits.

Sorry if that sounds rather negative, but hope it makes sense.

Best wishes and good luck with whatever you decide, Dave

I understand and that's great.  I always appreciate when you keep me between the fence posts. 😆 

Clarification - in case others got the same impression.  My intention is not to necessarily solicit for any kind of commitments.  It is primarily to see if there might be any interest. 

It has always been my contention when writing code (even if it is just for me) to consider... "Will I ever use this again even once?"  If the answer is no, the code goes into the Sketch file.  If the answer is even potentially... maybe, I'll put it in a library.  I'll comment it up more, so I can at least say... look at that $#!+... what was I thinking?  If I think it might be useful and consider publishing it, I'll write cleaner code so as not to show my underwear in public and double the comments in the code and formally document the capabilities, limitations and the API.  I'll also entertain people's suggestions... in the hope it'll be even more generalized for things I didn't think of, but might say someday... hey I'm glad I added that.

I know some people would want to code their own even if this system did exist.  But I think there might be a contingent here that just want to solve something simple like, get/set the temperature in the work shop or green-house a hundred yards away.  They don't want to learn all the intricacies and pitfalls of LoRa, Deep Sleep, RTC, GUI, Database, or Web servers so they never realize the feature.  If a library turns those challenges into a 5 line program, someone might benefit.

In this specific posting.  If there is not enough interest,   I have no need for most of the MPU's.  I won't add those.  I'll pick one LoRa library to use.  I won't support a WiFi version.   I'll hard code features instead of exposing them for optional configuration.  It'll just remain a private library.

 I have interest in the project but am not savvy enough to help with anything. Would the portal be able to handle video or security camera stills ?  Sounds like a very good project either way 🙂

Cheers,

Rainer

I too would be interested in that.  Unfortunately the library could not be written to handle those.  The LoRa communication is geared to "Long Range" (miles) and extreme minimal power (to run on batteries for months and even years).  To do that it sacrifices bandwidth (how fast it can send it) and size of the data sent (< 256 bytes).  It was really designed for remote sensors running off batteries.  As you can see, it would not be capable of either video or images.

Sorry,

@80stech If your interest is video and stills, get an ESP32CAM, but get the one with a MotherBoard. Here is a link on Amazon https://amz.run/7MGF    but those are relatively expensive. I have probably a dozen or more but most were bought on Aliexpress, likely 10 for $20.

 Yep I have quite a few as well but am currently using them remotely using port forwarding and would really like to have a portal to use for this and other projects.

Cheers 🙂 

I have some interest in LORA as well but was hoping to use that to avoid using the internet. 

@80stech I don't understand what you mean by portal. The sample code that comes with the board is a web server that allows you to control the camera. It sounds like you are doing that already for some purpose. Remember these are 2MP cameras, very low quality.

LORA can not be used for data intense applications, it is for passing small messages such as instrumentation (temperature, humidity, pressure) It has NO retry ability, no encryption, no ack/nak. You must build all that capability your self if you want it. I have designed several protocols in my days as an employee so have a 5th draft done so far. For me #5 is usually final, but this is a tricky beast. I have it down to 11 bytes of overhead. I could go smaller, but I am placing data integrity as my #1 priority.

Try to rephrase your question and ask again.

@zander

No question really,  I was just replying/commenting 🙂
