Error compiling about switchbot-mqtt-ble-esp32

[devWaves]

Have you been able to compile and upload any other example esp32 project? you can google to find examples or this one https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/

without changing the code, it should at least compile and upload. so it sounds like an arduino ide setup issue, not easy to tell based on error from what I can see

You are using a d1 mini esp32 correct?

if you are not using a fresh install of arduino IDE it can result in conflicting libraries sometimes. You can try uninstalling reinstalling, but I assume this is your first arduino project?

It's not my first project, I'll try uninstalling and reinstalling the IDE to rule out libraries.
As for other ESP32 projects, I just tried the example from the link you suggested, compiled without problem. Thanks

So, just wanted to close this.
First and foremost: thank you for having taken the time to answer!! I think it had something to do with other libraries I had installed but after uninstalling the ide and reinstalling everything from scratch, it worked.
