IWR1443: Is it possible to open individual 1 tx antenna by configuring channelCfg ?

Hi,

The  tx antenna channel can be set to any channel, 1 2 3 4 5 6 7 are available for this value.

Which SDK you are using? The latest one is SDK1.2

Also, when you change the TX channel, you should change the chirp config too. Here's an example.

sensorStop
flushCfg
dfeDataOutputMode 1
channelCfg 15 4 0
adcCfg 2 1
adcbufCfg 0 1 0 1
profileCfg 0 77 52 7 40 0 0 100 1 128 4000 0 0 30
chirpCfg 0 0 0 0 0 0 0 4
frameCfg 0 0 32 0 400 1 0
guiMonitor 1 1 1 1 0 1
cfarCfg 0 2 8 4 3 0 2000
peakGrouping 1 1 1 1 112
multiObjBeamForming 1 0.5
calibDcRangeSig 0 -5 8 256
clutterRemoval 0
compRangeBiasAndRxChanPhase 0.0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0
measureRangeBiasAndRxChanPhase 0 1.5 0.2

yes! that works! thanks Wesley, and could you tell me if there is any settings to reduce the power consumption? I've changed the frame periodicity to 1000("frameCfg 0 0 1 0 1000 1 0"), is there any other configuration I can set?

Hi Leon,

You can try Low power ADC mode, LDO bypass mode, and here's a ti-design you can refer:
