CCS / IWR1843： HOW TO SET 3tx bpm mode

Hi, there:

If you check SDK users guide and search for bpmCfg, you can find the information below:

Every frame should consist of alternating chirps with pattern TXA+TxB and TXA-TXB where TXA and TXB are two azimuth TX antennas. This is alternate configuration to TDM-MIMO scheme and provides SNR improvement by running 2Tx simultaneously. When using this scheme, user
should enable both the azimuth TX in the chirpCfg. See profile_2d_bpm.cfg profile in the xwr16xx mmW demo profiles directory for example usage.
This config is supported and mandatory only for demos that use Doppler DSP DPU (xwr16xx/xwr68xx). This config is not supported and is not needed for demos that use Doppler HWA DPU (xwr18xx/xwr64xx).

So, we only support 2TX BPM.   For 3 TX BPM, we do not have a system solution yet.  But if you need help to configure on the chirp configuration level, we probably can help.  Can you explain what functionality you need to enable 3 TX BPM mode?

Best,

Zigang
