B4R Question memory occupation of the Bluetooth library

Gerardo Tenreiro · Nov 1, 2021

Hello
I am testing the rESP32Bluettoh version 1.0 library that I downloaded from the forum and I observe that just initializing it consumes 71% of the memory of the ESP32 "uPesy ESP32 Wroom DevKit" that I have for testing
It is normal?
Can someone verify if the occupancy of this code is 71%
Thank you

It is normal. This is the size of the native Bluetooth SDK.

Don't worry about it. If needed you can increase the program storage by choosing a different partition such as this one:

B4X:

Sketch uses 927144 bytes (44%) of program storage space. Maximum is 2097152 bytes.

Thank you so much. I'll try.
Currently the program without the BLUETOOTH is at 90% occupancy to see with this option if I manage to implement everything necessary
By the way where can I find documentation of memory partitions?
Thank you

A more informative description is available in Arduino IDE:

The items are listed in the same order.

Thanks
I have already read the subject and I think I have it under control, for the moment I continue with the BLUETOOTH at times that it did not finish working as it should.
Thank you
