This error is from an attempt to move a working sketch from an older win10 machine to a newer win11 machine. I am using v2.5.3 of the IDE. I have tried to find the library AsyncMqttClient on the new machine but can’t seem to find it. I find variations of the name but nothing that seems to work. I tried to copy and paste the library from the older machine, however that did not work either. The sketch is one from your ebook “Smart Home etc” . The system is one with an esp32 , a bme280 sensor and I have added a SSD display. I use this device to monitor the conditions in a 3D filament storage unit. I also use the mqtt/node-red to monitor the results remotely on a pc or phone. I moved the sketch to the win11 machine as it is much faster and I want to add some more features. The device works well when it is uploaded from the win10 machine.
Do you have any idea as to what is going on here?

Hi.
Install the library the way it is mentioned in the Smart Home Course.
Download the .zip folder and then include the .zip.
It’s explained in the course.

Sara

Sara, Thank you for the reply. That is exactly what I did with all the libraries in that sketch as soon as I fixed one, the next one failed.
I then proceeded on and got a new error that I have no idea about. I am reluctant to change things in the sketch because it still works on the older computer. But here is the error msg.

Hi.
That error is because you’re using the latest version of the ESP32 core (version 3). There were some breaking changes from version 2 to 3 (https://randomnerdtutorials.com/esp32-migrating-version-2-to-3-arduino/).
We still didn’t have the time to update all our codes to the newest version.
The codes in the Smart Home eBook were created for version 2.
To make things work, you can do one of the following options:
1) downgrade your ESP32 boards installation. Go tom Tools > Boards > Boards Manager, search for ESP32 and downgrade to version 2.
or
2) Update the code to be compatible with version 3.
Replace the following Wi-Fi events:
SYSTEM_EVENT_STA_GOT_IP
SYSTEM_EVENT_STA_DISCONNECTED
with
ARDUINO_EVENT_WIFI_STA_GOT_IP
ARDUINO_EVENT_WIFI_STA_DISCONNECTED
If you’re using a code that uses PWM, the functions were also updated. You can see this updated guide:
https://randomnerdtutorials.com/esp32-pwm-arduino-ide/
If you have doubts, just let me know. I can fix the code for you.

Sara, problem solved. The new computer did not have the right boards installed. I got them installed and now the sketch has compiled.
Thanks for your help
