CC2538: AES / ECC / ZigBee Pro

Hi Support,

#1. Security Issue

• AES128/AES256: Can only use AES128… Could you advise how to use AES256? 

#2. ECC Security Feature

• Hardware Accelerator: How to use this? What is the SW implementation?

#3. Using ZigBee Pro solution from TI

• Core Application: Interfaces to PWM/I2C/UART/SPI

• Sometimes the link is wireless link is broken due to processing from the above interfaces. Please advise how to prevent wireless link break.

Thanks.
