MMM-GroveGestures / Python script is terminated

Have you tried testing the sensor?

Yes, and also when appear [GESTURE] Python script is terminated. It will restart soon. the gesture works well.

Pins are not stably connected

I exclude it.

@MMRIZE 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

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

I2C frequency is still too high. Set slower (lesser number than your trials)

I tried all speeds, maybe with 32000 seems better.
From this value (32000) do I go down or up?

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

I2C Bus overloaded, if you are connecting other i2c connections. (maybe more than 3 or 4s)
I exclude it. I have only Paj7620 and PIR sensor on GPIO…

I’m sure with the old version v2.23 of MM I always had the error messages but the gesture sensor always worked, with the new version v2.24.0 of MM sometimes the sensor stops working and I have to redo this procedure

@MMRIZE Thanks for your precious advises.

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

Egnos

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

MMRIZE

@Egnos
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.

Endpoint

Hi @ankonaskiff17, wich one of these?

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

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

https://www.sparkfun.com/products/16988 (It needs QWIIC environment)

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

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

@ankonaskiff17 Here is screenshot of BME688 0x77
It is connected to one of my Endpoints.
