Hi Robert,
You are right, `AUTOCRC` is on after reset, so `CRC_OK` gets appended to
the frame but is currently not checked.
I understand that corrupted packets with CRC errors are interesting if
you are doing research, in general I am not convinced handing those on
to upper layers though. Would it be sufficient for you to include CRC
errors in netstats?
Best, Thomas

Dear Thomas,
the CRC was generated already, also I need it for an evaluation and I
am
interested in packets with wrong CRC, so in my opinion the packet
should
be forwarded to the user, but with flag CRC_OK=0 set.
Best Regards,
Robert

Hi Robert,
First, to read and use the CRC_OK bit we will have to generate it.
Apparently that slipped through and we didn't notice so far, anyhow
I opened PR #6015 [1] to fix that. Thank you for leading us in that
direction!
Regarding a `crc_ok` bitfield I don't have a strong opinion.
Best, Thomas

Hey everyone,
I try to get CRC information for the received packet with the
CC2420.
When searching for CRC_OK there isn't really a way in RIOT.
I've looked at the *cc2420_rx* method and found that rssi is already
extracted. The same can be applied easily for the CRC of the last
packet.
I've also seen that there is the *info argument which is nothing
else
than *netdev2_radio_rx_info* from drivers/include/net/netdev2.h.
Would
it makes sense to add a "unsigned int crc_ok : 1" bit field to that
struct to indcate the CRC status or should it be implemented as a
NETOPT?
Best Regards,
Robert
