ESP32 Forum

Hi to all,
I'm developing a project using 2 ESP32-WROOM modules.
ESP1 is using Bluetooth classic and ESP-NOW.
ESP2 is using only ESP-NOW.
Connections are working great.

But when compiling for ESP1 I get flash to 95%, because of the huge WiFi library, and 90% of application algorithm is still to develop.
Is there a way to use only portion of this library?
For ESP-NOW usage, is necessary to have the WiFi in station mode.
But does this "Station mode" require the entire WiFi library?

Thanks to everyone.

What SDK are you using? If ESP-IDF, are you sure you're not filling up 95% of the app partition, instead of the entire flash? If that's the case, you can tweak the partition sizes and get some of your flash back.

Sorry, I'm relatively a newbie on this sector.
To code I use VS Code, with PlatformIO extension.
Actually, when I compile the ESP1 code, i get 95% "Application" and 14% "RAM"

Thanks

I don't know PlatformIO that well, so I can't tell you how to do that... but I'd suggest to look into resizing the partitions, as I mentioned before.

That's enough for me.
Knowing that I can increase/decrease partitions is a good news.
Thanks
