Other Parts Discussed in Thread: CC2520, CC2530
Hello,
I use CC2520 & CC2530 with our own evaluation board.
I'd like to build antenna diversity system using external RF switch with MCU.
CC2520 does have the function of SFD notification/exception, but it doens't have the preamble notification/exception.
Does anyone know how to detect the preamble (Appropriate GPIO setting value) and issue the exception to MCU?
(So, I'd like to decide the antenna using preamble detection signal.)
# if I set 0x40 to GPIOx as input signal, it seems like preamble detection... Please confirm the below.
Many thanks
