Hi,
I downloaded your firmware for the AQMIII to start work on my current AQMIII to get it fixed for the problem I reported earlier.
I finally managed to get the correct board in place (ESP32 Dev Module) and compiled the code as is after configuration.
I get loads of errors, the short version - all library resolve seems to go OK - is below. I can post the long version as well.

Any suggestion? (IDE version 2.3.6; and no this is not my daily doing so you may be verbose)
Should I update the libs, if so howto without damage?

Code:

Hi HansR

Fisrt of all try with IDE ESP32 2.0.3, as said it may not compile with newer versions.

I installed Board v2.0.3 and reinstalled the code from the zip (effectively removing the library updates)
The setup of the EDE shows as follows:

I Compiled and had the errors as in the txtfile in zip.

Hi HansR

From the errors below it seems Arduino IDE isn't using the provided libraries

Multiple libraries were found for "SoftwareSerial.h"

Ussually all Arduino libraries should be placed under this folder:

Code:
C:\Users\hansr\Documents\Arduino\libraries\

The code (without the libraries) can be placed anywhere, ex:

Code:
C:\Users\hansr\Documents\WeatherDuino_AQMIII

Errors show on the image bellow aren't significant, and the code compiles fine.

Two things:
1) You use IDE 1.8.19 I use 2.3.6
2) No matter where I put the libs, I don't get it compiled correctly

When the libraries are placed here C:\Users\hansr\Documents\Arduino\libraries and the software here C:\Users\hansr\Documents\Arduino\WeatherDuino_AQM_III\software it definitely does not work at all (no libs are found)

When software and libraries are on the same level (so, just as extracted from the rar archive, C:\Users\hansr\Documents\Arduino\WeatherDuino_AQM_III) it does compile but with errors.

Maybe I should use IDE 1.8.19 but a readme really would be useful)
I'll muddle along no solution yet.

HansR · 03-11-2025, 12:08

I just installed 1.8.19 (from here)

Unzipped your archive in C:\Users\hansr\Documents\Arduino\WeatherDuino_AQM_III => does not compile, it does not find any library

Moved libraries to C:\Users\hansr\Documents\Arduino\libraries. Then it compiles (note: this is very different from version IDE 2.3.6 where it seems to require the llibraries to be in the Sketch directory))

Then is does start compilation (after configuration) but I get the following errors:

Sketch uses 806201 bytes (61%) of program storage space. Maximum is 1310720 bytes.
Global variables use 44464 bytes (13%) of dynamic memory, leaving 283216 bytes for local variables. Maximum is 327680 bytes.

So it does compile - it does not give any error, only warnings which I highly dislike - but I have the following concluding remarks:

I think you should have a readme, it is dissatisfactory that there is no indication of the board required, the library location and that it does not compile out of the box. Not everybody works with the IDE on a daily basis. Once per 5 years is already frequent if one only uses AQMIII.
The warnings are not very comforting.
I think you should do some upgrade related to the new IDE and especially pay more attention to the location of the libraries relative to the sketch root
I am not going to replace my current firmware with this compile, I'll await your solution for the NULL in the return of the AirLink simulation (see this post)

Hello HansR,

I'm glad that finally you are able to compile the code.

I understood your complains, however let me counterpoint:

Quote:1 - I think you should have a readme, it is dissatisfactory that there is no indication of the board required, the library location and that it does not compile out of the box. Not everybody works with the IDE on a daily basis. Once per 5 years is already frequent if one only uses AQMIII

For every WeatherDuino firmware version, there is a clear information about which IDE version should be used as also the boards version that should be used. For the case of the WeatherDuino AQMIIII:

Quote:WeatherDuino Air Quality Monitor III - v6.1_b010 - Release date: 2022-05-21
Tested with Arduino IDE 1.8.19 and ESP32 2.0.3 (may not compile with other versions).

-------------------------------------

Quote:2 - The warnings are not very comforting

Warnings are common when compiling Arduino code, and they are just that, if the software will compile successfully then it will work as expected.

-------------------------------------

Quote:3 - I think you should do some upgrade related to the new IDE and especially pay more attention to the location of the libraries relative to the sketch root

In the short term there are no plans to convert any of the WeatherDuino software to work with Arduino IDE 2.x.x
I think its not my responsibility teach how to use Arduino and where Arduino libraries should be installed. Please refer to this statement on the WeatherDuino Wiki:

Quote:Do I need to have Arduino programming skills?

No, there is no need to have programming skills. However its assumed that the user has a minimal knowledge of the Arduino IDE. It is necessary to know how to install libraries and how to make minor edits to code.
Editing the code is only required to change the value of some pre-defined settings, to make the software work correctly with the set of weather instruments you intend to use, and to define some user preferences, such as using metric or imperial units.

-------------------------------------

Quote:4 - I am not going to replace my current firmware with this compile, I'll await your solution for the NULL in the return of the AirLink simulation (see this post)

In a few days I will release a new WeatherDuino AQMIII firmware version with a fix for NULL in the return of the AirLink simulation.

Thank you for your comments and concerns.

Hi wergk_ag,

Thanks for your remarks pointing out where I went wrong.

Hello Hans,

I am the one who should be grateful for your collaboration.
My apologies for not always being able to meet user expectations.

A new firmware version was released today for the AQMIII; I hope it solves the NULL issue. Please provide feedback.

Hi werk_ag,

The problem is solved and AQMIII now is correctly read by CMX v4.7 (to be released later)
If any issue - it was a quick test - I will get back to you but it looks reading the data which is the result I am looking for Like

regards,
