ECG and pulse sensor at the same time

Hi! I'm trying to collect both my ECG data and data from pulse sensor at the same time. I did the setup just according to the file (things like 5-lead ECG and purple wire of pulse sensor connects to D11). But when I do them independently, everything's fine. When I do the 2 things together, the analog channel 1 in my data file is all 0. I'm wondering if there's anything I missed? Thanks!!!

    Ruabbita, hi.

    I assume you are using the Pulse Widget,

    https://docs.openbci.com/Software/OpenBCISoftware/GUIWidgets/#pulse-widget

    Which puts the Aux data stream (normally carrying the 3 Accelerometer values) into what is called "Analog board mode" for you. This is what records the D11 analog value from the pulse sensor.

    https://docs.openbci.com/Cyton/CytonSDK/#board-mode

    Assuming your stream is already going, when you start the Pulse Widget. Can you be more specific about the steps you take when you say:

    When I do the 2 things together, the analog channel 1 in my data file is all 0.

    You are referring to the Aux channel or the regular ECG channel 1? The Pulse Widget data disappears? Or ECG channel 1 disappears? What happens to the live Time Series display? Etc. The Aux data for D11 is separate from EXG channels 1 to 8. Mentioning Richard @retiutut.
