DCA1000EVM: automated data recording with AWR1642

Hello,

I would like to record radar data in an embedded setup, e.g. the AWR1642 and DCA1000 are connected to a raspberry Pi or Asus Tinkerboard.

I currently have the following setup:

• the AWR1642 has the binaries of the SDK demo uploaded
• the AWR1642 is connected via usb to the Pi
• the Pi sends commands via CLI (from python) to the AWR (e.g. the configuration files provided by the SDK
  e.g. like this: https://github.com/PreSenseRadar/OpenRadar/blob/master/mmwave/dataloader/radars.py
• The DCA1000 is connected to the Pi via Gigabit Ethernet
• The Pi sends commands via UDP (from python) to the DCA, although I am not sure what commands I need to send(?)
  e.g. like this: https://github.com/PreSenseRadar/OpenRadar/blob/master/mmwave/dataloader/adc.py

When I send my configurations, the radar starts measuring (DS3 is on, frames are audible) but on the DCA the LEDs

LVDS_PATH_ERR and HDR_ERR (red) light, together with the DATA_TRANS_PRG (green). The DCA doesnt stream any data over Ethernet.

I use the following config file:

I use the DCA commands from the "OpenRadar" project linked above.
I must be missing something?

Help and hints are appreciated :)
Kind regards
