Farm Data Relay System not able to compile in PlatformIo but in Arduino IDE

1

The Farm Data Relay System is a very useful library to build an independent network of sensors via ESPnow, LoRa, WiFi and UART connection.
Farm-Data-Relay-System
Unfortunately I was not able to compile the example code for the UART gateway with PlatformIo. Even with help from my coworker :wink: Copilot I found no way after two days. Although I dont like to work with the Arduino IDE I tried finaly to compile the code with it and … it worked without any error. I would be glad if somebody could explain me the reason. As there is no library.json in the FDRS repo I uploaded the header files in /lib/FDRS/src folder.

The FDRS library is using the newer ESP-NOW libraries from the Espressif Arduino 3.x core. But you’re still on Espressif Arduino 2.x.

To get the latest Espressif Arduino 3.x you can use the community fork pioarduino/platform-espressif32:

platform = https://github.com/pioarduino/platform-espressif32/releases/download/53.03.13/platform-espressif32.zip

This will use the Espressif Arduino version 3.1.3.

You’ll find more about the available versions here

Also add the the FDRS library to the lib_deps.
This will download the library automatically when the project is built.
See lib_deps — PlatformIO latest documentation

Your full platformio.ini should look like this:

[env:esp32dev]
platform = https://github.com/pioarduino/platform-espressif32/releases/download/53.03.13/platform-espressif32.zip
board = esp32dev
framework = arduino
lib_deps = 
  bblanchon/ArduinoJson@^7.3.1
  https://github.com/timmbogner/Farm-Data-Relay-System@2.0.1

Aside from a few warnings caused by the FDRS lib still using deprecated ArduinoJson functions and a few type conversion warnings, the project should now build successfully:

Many thanks for your quick response!

I updated my platformio.ini to get the recommended Espressif Arduino version 3.1.3.

platform = https://github.com/pioarduino/platform-espressif32/releases/download/53.03.13/platform-espressif32.zip

It gave me an error and recommended me to check the last version of platformio:

python -m pip install -U platformio

This did not work either. Unfortunately I did not copy the error messages when I closed the window and I do not know where PlatformIo stores logfiles related to this.

After that I opened a new window in PlatformIo and tried to build a new project, but now I was not able to load the boards list and recent projects anymore and gave me this messages.

I didn’t notice your edit. In such a case it is better to create a new reply.

The error you have is strange and should not happen when changing just the platform setting.

It looks like your espressif platform or the whole PlatformIO installation is broken.

  • Close VS Code
  • delete C:\Users\username\.platformio
  • Start VS Code
  • Wait until PlatformIO finished reinstalling the necessary files and platform

Many thanks for your support! I will report later.

Many thanks again for your help! I tried your advises serveral times again and again.
Removed VSC and installed it again. The FDRS had been installed by PlatformIo in

C:\esp32\RpmSensor\.pio\libdeps\esp32dev\Farm-Data-Relay-System

I renamed all the .ino files and had a look at the correct alignement of the functions (setup and loop at last and #include <Arduino.h> on top).

But it did not work and I got errors and errors compiling it.

..................................

In the last moment after lots of hours of wasted time when I was about to turn to the Arduino IDE … I remembered the main difference between PlatformIo and Arduino IDE and perhaps the reason why all the error messages did show up althoug #include <Arduino.h> has been done in the .cpp files !!!

I gave them a last chance and included Arduino.h in every header file of the FDRS library.
And… :drum: It worked finally! :pray::pray::pray:

By the way, GitHub Copilot had many ideas to solve the problem which were not helpful but time consuming!

I have had much the same experience using chatGPT to try and solve issues with platformIO, ending up going round in circles and wasting hours. IMHO if sivar2311 can’t solve an issue then AI can’t either. I love platformIO and the joy it gives when a project is successfully completed.

I am pleased that this has worked for you, but unfortunately I have to tell you that this is the wrong way!

I have to withdraw my last post because I misunderstood the statement. If the changes refer to your own .cpp files and not to those of the FDRS library, this is of course correct.

Hi I noticed you made a comment about setup and loop being last. I assume you mean after the functions. You do not need to do that if you use function prototypes at the top of the file. Alternative you can put the prototypes in a .h file.
The Arduino IDE doesn’t require one to use function prototypes but proper C/C++ does! unless you do as you did and put setup and loop after when a function is called, i.e. at the end.
Anyway I am about to try FDRS so your experience of it with platformIO will be helpful.

Many thanks! My problems occured when I tried to integrate FDRS in a sketch containing some other libraries having little experience in that. In the meantime I found out how to do. My platformio.ini for the FDRS project looks like this and works perfectly.

Thank you for sharing further information. I am pleased to see you get it working with the latest ArduinoJson . I have had to address those issues with ArduinoJson too.
