Original question:

IWR1443: Raw time data from each RX channel

Part Number: IWR1443

Team, 

If I need to turn on Rx4 and Tx1 only on and leave all other ports off, how do I configure the profile?

Should I use:

channel cfg 8 1

or use

channelcfg 4 1

Thanks

Viktorija

    Hello Viktorija,

    It looks like you are referencing one of the CLI (Command Line Interface) commands from the mmWave SDK out-of-box (mmw) demo. Those commands are documented in the mmWave SDK user guide. Assuming you are using mmWave SDK 1.2 (currently the latest SDK that supports IWR1443), they are documented in section "3. 4. Configuration (.cfg) File Format".

    For mmWave SDK 1.2:
    The first parameter for the channelCfg command is "rxChannelEn", which is a bitmask where each bit corresponds to an RX antenna (from most-significant to least-significant bit: bit3 = rx4, bit2=rx3, bit1=rx2, bit0=rx1). The value to use to only enable RX4 would thus be 1000b = 8. The second parameter is "txChannelEn" which is a similar bitmask for the TX antennas and can be set to 1 to only enable TX1. The third parameter is "cascading" which should be set to 0. Thus the command would be "channelCfg 8 1 0".

    If you are using a different mmWave SDK version then please refer to the user guide for that version.

    Please mark the thread as answered if the question is resolved or reply if more support is required.

    Regards,
    John
