IRAM constrains in ESP32

I’m developing a BLE code in ESP32 using nimble stack, that itself consuming around 70% of the IRAM. I want to integrate few other peripherals like CAN, SPI.

How can I optimize or reduce the IRAM size with working functionality?

    @edison_ngunjiri_94786 @umeshlokhande any suggestions?

    Hi @iamnarendrans try to *optimize memory* using `menuconfig` settings. By allocating less memory space means reducing Blocks and Buffer counts, you may gain some additional ~20KB of heap. I’d suggest play with menuconfig to find out best possible IRAM for other use.

    That’s where, I’m playing. As of now I reduced 5KB, I have to reduce a lot

    Is there any other chances to do the same @umeshlokhande
