    Hi All,
    I am developing application around X4M03 that setting up XEP configuration with down-conversion enable and fps set to 330.
    There will be 184 base band IQ sample which is 368 floats data.
    But every time I am getting one or two frame per second, is that XEP set fps is failing? (Please give up some pointer for same).
    I am using mcp_wrapper_1.3.0 C code,
    Below are sensor configuration
    /* Xethru x4m03 sensor configuration */
    x4_dac_min=949
    x4_dac_max=1054
    x4_iteration=232
    x4_pps=1
    x4_fps=330
    x4_offset=0.2
    x4_fa1=0.4
    x4_fa2=10
    x4_dc=1

    Regards,
    Snehal

    Hi All,

    Is changing serial baud for X4M03 will help for this issue?

    Hi Snehal,
    I have performed FPS tests on my computer (windows 10 - 64 bit) with your settings. All tests are ok. May be there is a time consuming part in your code, which can explain the dramatic drop of frames.
    Hope this help to find solution on this issue.

    Best regards,
    Chouaibou.

    Hi Snehal,

    You can try to test with low FPS or just output frame counter at first to verify if this is caused by speed limit.

    Hi,
    I have check frame counter and every frame are in the sequence.
    But when I set serial baud to 921600, I am getting all frames at 330 fps.
