I am using the AES-BCM4343W which includes the STM32F411 MCU (512KB FLASH and 128KB SRAM).

My application is utilizing both Bluetooth and WiFi and I am running up against the SRAM limit.  I tried suggestions I have found in the forums, but these have not had any success in reducing SRAM usage.  I am using WICED Studio 6.1.  Any suggestions would be appreciated.

Check if this helps:

CYW4343W + STM32F411: BLE & Wi-Fi, memory issues 

I hope Cypress can release bug fix sdk ASAP.

It's painful for users to pick up several fixes manually from the forum.

You can check SRAM memory to optimize the SRAM usage.

Making the BT firmware "const" made a huge difference.  The other suggestions did not make any difference, though I have not gone back and tried them after fixing the issue with BT firmware.
