The packet has been waiting for such a long time in the input buffer (4min) that it is discarded.
•
Fragment - sequence error
The serial number of the fragment does not correspond to that expected.
•
Fragment - total number error
Information about the total number of fragments does not correspond to the previous fragment.
•
Fragment - source address error
The received fragment is from another source address (serial number of radio modem) than the
previous fragment.
•
Fragment - receive timeout
The next fragment (does not apply to the first one) did not arrive within the timeout period (timeout
is given by the transmission time of a single fragment in RFC).
•
Fragmented packet being transmitted -> new packet delayed
Transmission of a packet has been held up (the packet is stored in the input buffer) owing to
transmission or receipt of a fragmented packet. During receipt this doesn't apply to the first fragment
(it is not yet known that it is a fragment).
•
Fragment - missing first fragment
A fragment not marked as the first has been received (and the first hasn't yet been received).
•
Compression inflate error
Packet decompression error.
•
Compression deflate error
Packet compression error.
•
Receive process interrupted
Received data is damaged because transmission occurred during receipt.
•
(ERR2) - header corrupted
FPGA does not understand the packet header (another version of the protocol in the air or interfer-
ence).
•
(CRC16) - header corrupted
CRC16 didn't appear in the header of the received packet.
•
(CRC32) - data corrupted
CRC32 didn't appear in the data of the received packet.
The following messages only for
Number of repeaters
> 0 :
•
Returned packet -> discarded
(for NoR>0)
The same packet that was sent arrived back during the timeout period.
•
Same packet -> discarded
(for NoR>0)
The same packet, but with a different source address, was repeatedly received during the timeout
period.
•
TX delayed -> new packet delayed
(for NoR>0)
Packet transmission has been held up owing to activation of delays related to the repeater.
