Other Parts Discussed in Thread: IWR1642BOOST, IWR1642
Hi,
I'm using the IWR1642BOOST (ES1.0) together with DCA1000EVM. I want to increase the number of frames recorded, so I change line 168 in the DataCaptureDemo_xWR.lua script from ar1.FrameConfig(0, 0, 8, 128, 40, 0, 1) to ar1.FrameConfig(0, 0, 80, 128, 40, 0, 1), but then I get an error message

If I change the number of frames from 80 back to 8 again, the recording works as intended. There is a similar thread on this: https://e2e.ti.com/support/sensors/f/1023/t/697731?DCA1000EVM-Modifying-frame-number-in-DataCaptureDemo-xWR-LUA-script-based-on-quick-start-guide-instructions
