DCA1000EVM: Decrease ethernet packet delay from 25us to 10us

Hello Allen,

Could I get a screenshot on how the packet delay is being set within the JSON file?

Hi Pedrhorn,

Here is the json file.

Hello,

Is this behavior seen as well when using mmWaveStudio and one of its default JSON scripts?

Hi Pedrhorm

No, customer could not use GUI in their test system, it was thought the JSON file should work with mmwave studio GUI. Actually this JSON file attached is from the mmwave SDK and they just modified the packet delay.
