Host MCU memory space required for WiFi host drivers and BLE libraries to integrate ESP32- WROOM 32 UE

[kotteswaran P]

Hello Experts,

We are trying to integrate ESP32 - WROOM 32 UE as a radio module with MSP430F5438A host MCU.

Earlier we were using Microchip's RN171 where it has WiFi. We are planning to replace RN171 with ESP32 to get WiFi and BLE support.

MSP430F5438 has 16Kb RAM and 256Kb Flash. Right now we have 3Kb RAM and 59Kb Flash available on host MCU.

Is available memory space really enough for ESP32 drivers and libraries to place on host MCU.

Could you please let me how much memory space required on host MCU to port drivers and libraries to bring esp32 full functionality

Thanks,
Kotteswaran

If you are running esp-at firmware on WROOM 32 UE then you only need simple command support on host.
