TTGO T-Beam topic

Thank you jezd. I’ll read LMIC library.

Thanks! you are my master now!!

Hey Guys,

i am an absolute beginner in LoRa. I finished my Gateway on PiZero+RAK831. Now i tried to setup a TTGO-Beam as a GPSMapper with Display. Is there anywhere a step-by-step tutorial for use with PlatformIO?

Thanks and greetings

Did you search for t-beam mapping node step by step?

I want to create a paxcounter with a t-beam but the sketch needs platform Io.
This program does not work with my windows, I am sick of it.
Is there a way to upload this sketch
with Arduino program like other sketches?

PlatformIO is a well elaborated and documented IDE. If it does not run on your system, you probably have issues with your system.

My system is fine, but it gets more and more trashed thru such inflated, tinkered and user unfriendly software like atomio and platformio. It is totally ridiculous that I need to have a few 100mb software to compile and upload a few kb to an esp32. However, if lean and efficient software is not available for this sketch, I am not interested in spending lifetime in this sketch.

Keep the tone civil. If you don’t like a platform you don’t have to use it. However the author of software is free to choose a development platform so might not be able to use their code. That is a choice you have to make. Complaining about the choice the author made regarding a development platform is not done.

I agree with @kersing’s standpoint.

That said, you seem not to be aware of the advantages and power of PlatformIO (and VSCode).
Also, this is 2019 and a few hundred megabytes for an IDE and a platform tool chain are quite common.

The author of ESP32-PaxCounter has deliberately chosen to use PlatformIO. Apparently because having ran into limitations of the Arduino IDE and needing something more flexible and more productive (no pun intended).

I’m sorry to hear that PlatformIO does not run well on your computer, but that is probably more related to your computer than related to PlatformIO and/or Visual Studio Code.

PlatformIO uses many of the same tool chains and Arduino cores as the Arduino IDE. From that perspective I would be surprised to see much difference in size between them.
You complain that you need “few 100MB” software to compile and upload a few kb to an esp32.
Well, the Xtensa toolchain for ESP32 and ESP32 Arduino Core together are about 500MB in size.
This is independent from any IDE, so also independent from whether using the Arduino IDE or PlatformIO (but each installs their own separate copy of them). Your negative remarks regarding software size, lean and efficient therefore seem to be unsubstantiated.

If PlatformIO is not an option for you then the same holds for ESP32-PaxCounter, there is no reason to be negative about that here.

Fine for you. I will not use platformio again or give it another chance.
Software that has a crappy usability is useless in my eyes. Stick with it and be happy with it. This is not the place to discuss about that and I am not interested in discussing about because it is useless.
But it shows that til now, no one had the idea to give the alternative solution that the platformio files could be modified to work with Arduino…THAT would have been helpful instead telling me how great platformio is and my system might be the problem…however.

If you don’t want your system to get “trashed” by software you install, there are various means to isolate installations inside containment units you can later remove without any impact on the rest of your system.

I’m thinking about virtual machines, docker, etc.

But of course it takes some effort to setup…

Yes, you are right but as Docker was swallowed by Mirantis we will see how long this will work. Sorry to all for posting my frustrations about platformio and writing too much rubbish in this thread…maybe I will post a workaround how to modify platformio sketches to use it with Arduino if I think this is a suitable workaround.

Its only recently that running PlatformIO on a virtual machine has been useable in my view. I did try it some 18 months ago, on a decent specification desktop PC running VMWare Workstation 14. The VM is Windows 8. At the time VS code, and hence PlatformIO ran like a complete dog in the otherwise OK VM, maybe a minute or so to start, if it started at all.

Whatever the problem with VS code was, it appears now to be solved, and Platform IO is now useable in a VM.

I totally agree.

Possibly because your behavior was not inviting to motivate people to spend energy on that and you bash the tools and software from the people that you seek assistance from.

A similar remark:

You seem to have a certain opinion of what other people need to do in order to make your own code (samples) work and try to make that clear in your posts. That is not respectful and is not tolerated on the forum.

Maybe it’s because I am german and not native english speaker. However I share my experiences instead let other people waste their time. What is wrong showing others how to quickly setup a mapping node and avoiding mistakes? Nothing.

There is nothing wrong with showing others how to quickly setup a mapping node and avoiding mistakes. Positive contributions are what the forum is meant for.

What is wrong is negatively hinting/complaining that things have not (yet) been done by other users. “But it shows that til now, no one had the idea to give …” reads like a sneer to other posters that have tried to assist you, and “… but takes time til it works. So I am wondering why nobody did a tutorial for that til now” also does not sound like a compliment either.
While this may be related to English not being your native language, it certainly requires attention and so does language like “inflated, tinkered and user unfriendly software like”, “It is totally ridiculous that” and “I am not interested in spending lifetime in this sketch”.

Discussion closed. Let’s go back on track and stay on topic.

The paxcounter code is open source, so why don’t YOU start a port to Arduino IDE (or maybe the new Plus IDE) instead complaining here? If you want to just consume software, please move on to commercial suites, pay for it and push your complaints to the support hotline.

Loud and clear!

Ok back on track…
I was wondering why some 868mhz antennas works better then others. Meanwhile I have a few antennas that were delivered with a t-beam.
After removing the plastic you see the differences. The 868mhz tuned one is the right one according to my nanovna. The left one is better tuned at 915mhz for the us market…!

It is often a surprise what differences you get to see when removing the caps from antennas that look similar on the outside.
