      @Egnos said in MMM-GroveGestures / Python script is terminated:

      Too long cabling, > 30cm. The signal would be weaker or noisy.

      It will surely be longer, 40 or 50 cm

      Hopefully not, over 30cm long cabling could be the issue. (You wrote 40~50cm, is it right?)

        @MMRIZE Yes, from the GPIO to the sensor there will be about 40/45 cm…

          40~45cm seems somewhat too long. Could you build it shorter? or use a lower frequency than usual case.
          Ref. these;

            @MMRIZE The path of the sensor cables (Yellow, red, white and black) is this:

            Maybe I could shorten the wires a bit…

            Thanks for the links.

              @Egnos Maybe Sparkfun Midpoint and Endpoint to give you ample length. They tout over 100’ with those devices.

                  There are several “I2C Extenders” (Or “Active Terminator”)

                  I haven’t tried this kind of thing, but it is worth researching.

                    @Egnos You want what is called a Midpoint which is Midpoint.jpg
                    Also need an Endpoint which is this Endpoint.jpg

                    I whipped this together in double quick time so pardon the lack of tidiness.
                    For reference sake I focused on a couple of BME688’s to give you sort of a benchmark.
                    First is screenshot showing both BME’s running. Had to do jumper on one to get a second address 0x76 and 0x77

                      It is connected to one of my Endpoints.
