Original question:
Linux/IWR1642: Issue with sync pattern ( 8 byte magic bytes)
Team,
When capturing ADC samples with IWR6843ISK/DCA1000 over Ethernet - I see from the capture datafile a HSI header per chirp - as below.
If I loose a packet and therefore HSI header, how can I resynchronise to the start of frame or profile index ? Is there a way of using User bits for this ?
Thanks.
Hello,
Current frame work (UDP) does not allow re-synchronize after a lost packet.
To reduce it's periodicity you could try increasing the Packet delay shown below.
Thanks and regards,

Hello,
Typically there could be out of order packet could be received on the host PC side, It could be interpreted as dropped packet.
On the newer version of mmWave studio it encapsulate the out of order packet and corrects it.

Also in the new version of mmWave studio some feature enhancement is also made one of the item is "Packet reorder utility is no longer required" if you use the mmWave studio.
If you use the standalone DCA1000 with CLI interface, There is reference code is shared you could access from the below link:
C:\ti\mmwave_studio_02_01_00_00\mmWaveStudio\ReferenceCode\DCA1000
You could refer Userguide from the below link also available on the above link after the installation.
Please note that this release incorporate correction for the packet out of order reception at the host PC side.
Thanks and regards,
