Part Number: IWRL1432
Other Parts Discussed in Thread: IWR1443

Hi , datasheet says IWRL1432 has transmitter binary phase shifter

Are there any demo or example has a CLI to set this?
or How to set phase shifler?

Hello,

You can set it to either TDM or BPM mode, but nothing custom. This is done in the CFG file, within the chirpComnCfg parameter under the ChirpTxMimoPatSel field.

More information on these two can be found in our MIMO guide

Hello Abhishek,

BPM stands for binary phase modulation. Modulation and shifting are synonymous, please look at the BPM section of the document listed above.

Hi Pedrhom.

I have used iwr1443 before, in its mmwave sdk,
There is a cli command ‘profileCfg’as follows

There is para txPhaseShifter to set tx phhase. (but for iwr1443 it is not work)

For IWRL1432 , Is there a parameter for this, or is there an example containing a similar cli command

Hello,

We do not have this for 1432/6432 because it would not make sense to do this with only two TX antennas as it would not have much coherent gain.
