Hardware filtering of packets that fail CRC


#1

Is there any way to do hardware filtering of radio packets that fail the CRC check? Ideally, what I’d like is to prevent the RF interrupt from being triggered at all if the radio packet that is received fails the CRC.

Hello. As far as I know, there is no way to filter out packets with a bad CRC in hardware. If you figure out how to do it, we would be happy to hear about it. Section 13.8.3 of the CC2511F32 datasheet, which is entitled “Packet Filtering in Receive Mode”, talks about address filtering and maximum length filtering, but does not mention CRC filtering.
