Description

Switching form Arduino 2.x to Arduino 3.x increase flash size from

RAM:   [==        ]  16.8% (used 55180 bytes from 327680 bytes)
Flash: [======    ]  58.7% (used 769481 bytes from 1310720 bytes)

to

RAM:   [==        ]  16.6% (used 54332 bytes from 327680 bytes)
Flash: [=======   ]  65.9% (used 863499 bytes from 1310720 bytes)

it is around 10% of memory, without changing of code. Looks that arduino-esp32 overhead increased. Maybe here is some place for size optimization? Maybe some refactor needed to allow compiler/linker remove unused part of code?

yes. this is a fact. it is caused by many changes in ESP-IDF, supported WiFi encryptions and more. It is normal for that to happen
