Hi
i'm using your lib on an board with a ESP32 wrooom for the very firts time, but

even a small sketch seems use a lot of resources.
for example the attached sketch use 83% of the program storage..

Sketch uses 1096561 bytes (83%) of program storage space. Maximum is 1310720 bytes.
Global variables use 38004 bytes (11%) of dynamic memory, leaving 289676 bytes for local variables. Maximum is 327680 bytes.

thank for your attention

My suggestions:

• use OTG (i.e. Serial)
• or use WiFi
• or use Bluetooth
• BLE is your last choice

Another thing is ... declare the app to be a "huge app" ... e.g. with with PlatformIO, put in platformio.ini:

board_build.partitions = huge_app.csv
