Hi,
I am using a CC2541 chip for communication in proprietary mode.
I want a trigger signal as soon as a packet is detected(SYNC word matched). Currently, I am using the SFD bit as a trigger by redirecting it onto a GPIO .But the latency between the the SFD bit going high and actual end of SYNC word in transmission is around 12-13 microsecond which is high.
Why does it have such a huge delay? Is this delay due to hardware(time required to demodulate, de-whiten the packets) ?
Is there anyway to reduce this delay and detect a packet quickly?
