IWR1443: SDK1.1, capture demo, how to repeatedly trigger 1 frame of a preset configuration?

hi, 

in IWR1443 capture demo in SDK1.1, I want to repeatedly trigger 1 frame of a preset configuration.

The configuration is as below:

flushCfg

dfeDataOutputMode 1

channelCfg 15 3 0

adcCfg 2 1

adcbufCfg 0 0 1 1

lowPower 0 0

profileCfg 0 77 5 5 29 0 0  9 1 128 6000 0 0 48

chirpCfg 0 0 0 0 0 0 0 3

frameCfg 0 0 128 1 30 1 0

setHSI LVDS ADC disable

sensorStart

I suppose this will configure the sensor and trigger 1 frame.

But when I want to take another trigger as soon as the last frame is done, where shall I add code, and what code?

I tried to add rlSensorStart(RL_DEVICE_MAP_INTERNAL_BSS) in case RL_RF_AE_FRAME_END_SB in CaptureDemo_eventCallbackFxn.

but it does not work? 

Any suggestions?

Thanks!
