MMM-GroveGestures module automatically stop running

I found that the module automatically stop running. The console log is as followings:

2019-03-18T22:54:47 <log> Keyboard Interrupted (/home/pi/MagicMirror/modules/MMM-GroveGestures/node_helper.js:39 Class.log)
2019-03-18T22:54:47 <log> [GESTURE] Gesture script is finished. (/home/pi/MagicMirror/modules/MMM-GroveGestures/node_helper.js:39 Class.log)

There are not keyboard or mouse in Raspberry Pi 3b+. During the whole process, I did not touch any windows from remote ssh session.

The config is very simple. There is one or two modules in each page. the config is as following:

    modules: [

How to troubleshooting this issue? Could you give me some suggestion? Thanks in advance!

Have a nice day!

When did that error occur? on start? or some period after running?

Keyborad Interrupt means, Grove Gesture detection script (grove_gesture_sensor.py) was quitted by external interruption (Sorry for confusing, someday I'll edit the error message) This error will occur when;

• User stop program by force (by example; Ctrl + C with keyboard)
• Your Sensor and RPI has a problem to connect through GPIO pin (bad assembly, electricity shortage, ...) => Check your assembly.

Well, I'll try to modify source to restart when that error occurs, Plz wait a few days.

@eouia Thanks for your suggestion.

I'll check these connections although I don't think so. The PAJ7620u2 sensor was tightly connected Respeaker-2mic I2C interface by one 4-Pin cable.

This issue often happened during some period after MagicMirror running. NO KEYBOARD, NO TOUCH, even if NO SSH SESSION (disconnect ssh session).

According to the issue https://github.com/eouia/MMM-GroveGestures/issues/5, I modified i2c speed to 10000. Although after that the issue happened one time again, I found that the issue seems like disappear. I'm not sure. I'll pay attention on it.

[eouia]

Maybe some i2c speed might make too fast or too slow connection between sensor and RPI. I didn't think about it before. I hope you'll get a good luck. (if so, I don't need to edit... :D)

If the issue will not happen again in future, I'll tell you. Thanks for your fantastic application and your conscientious attitude!

@eouia When the i2c speed is 10000, the issue unluckily appeared two times during 24 hours. Although it seems like that the frequency decreases, I still adjusted the i2c speed to 32000. The issue hasn't happened in past 30 hours. Let me keep watching it.
