Struggle using `termux-sensors`

[Benjamin-Loison]

On my Fairphone 4 LineageOS 23.2:

termux-sensor -l

Output:

{
  "sensors": [
    "lsm6dso Accelerometer Non-wakeup",
    "lsm6dso Accelerometer Wakeup",
    "ak0991x Magnetometer Non-wakeup",

}

Would help Benjamin-Loison/android/issues/27 and Benjamin_Loison/EXIF/issues/4.

termux-sensor --help

termux-sensor: illegal option --

termux-sensor -h

Output:

Usage: termux-sensor

  -h, help           Show this help
  -a, all            Listen to all sensors (WARNING! may have battery impact)
  -c, cleanup        Perform cleanup (release sensor resources)
  -l, list           Show list of available sensors
  -s, sensors [,,,]  Sensors to listen to (can contain just partial name)
  -d, delay [ms]     Delay time in milliseconds before receiving new sensor update
  -n, limit [num]    Number of times to read sensor(s) (default: continuous) (min: 1)

termux-sensor -a

hangs at least for tens of seconds without returning anything.

termux-sensor -s "motion_detect"

Output:

{}
{}
{}
...

every second it seems without changing output while moving physically the phone.

termux-sensor -n 1 -s 'gravity  Wakeup'

Output:

{
  "gravity  Wakeup": {
    "values": [
      -0.15379945933818817,
      -0.1192815750837326,
      9.804718971252441
    ]
  }
}

if flip the phone:

termux-sensor -n 1 -s 'gravity  Wakeup'

Output:

{
  "gravity  Wakeup": {
    "values": [
      0.14795950055122375,
      0.1675386130809784,
      -9.804102897644043
    ]
  }
}

Force stop Termux API helps having commands not hang.

[Benjamin-Loison]

Output:

{
  "stk_stk3a5x Proximity Sensor Non-wakeup": {
    "values": [
      0
    ]
  }
}
{
  "stk_stk3a5x Proximity Sensor Non-wakeup": {
    "values": [
      5
    ]
  }
}

acts like binary.

[Benjamin-Loison]

termux-sensor -s "pedometer  Non-wakeup"

Output:

{}
{}
...

DuckDuckGo search sns_smd.

LineageOS/issues/android/-/work_items/6356 explains sns_smd meaning.

So no other relevant sensors it seems.

[Benjamin-Loison]

Note the multiple occurrences of pedometer, I have verified that it is the only one, only considering Non-wakeup.

What is the difference between Non-wakeup and Wakeup?
