Waking up using 12V and IMU

Edge Systems
1

Currently, I am looking for a way to wake up the Particle One device. We would like to put it in a sleep mode and wake up using two sources: an input from the M8 pin 2 connector OR any motion.

I checked this link

https://docs.particle.io/reference/asset-tracking/tracker-edge-firmware/#trackersleep

it mentioned

motion (IMU), BLE, GPIO pin interrupts,

However, I wasn't able to see any APIs regarding the motion wake-up. I am able to see time based wakeup, BLE, and GPIO. I saw the motionservice but the document discourages to use that.

Second, the wake up from +12V input (rising edge trigger). I looked at the schematic, https://docs.particle.io/datasheets/asset-tracking/tracker-one/#tracker-one-schematics and I can't see if there is a way to wake up the Particle one. If that isn't possible, I think what we can do is do a voltage divider and connect the output to one GPIO pin for wake-up.

Also, is there a way to tell if the Particle Tracker one is operating on battery or on M8 pin 2 12V?

Third, is it possible to have two wake-up sources at the same time (motion and power +12V)?

thanks!

Yes, this is possible. Wake on movement is not on the sleep settings is that it’s handled automatically based on the configuration you’ve set in the product configuration in the console. Essentially the options you pass in code are in addition to the ones from the cloud.

To wake on power applied, see this post. Basically, you wake on the pin:

TrackerSleep::instance().wakeFor(PMIC_INT, FALLING);

Hi Rick,

Thanks for the reply. I implemented it but I am having challenges making it work.

This is the code on my initialization setup

    // Initialize tracker stuff
    Tracker::instance().init();

    TrackerSleep::instance().wakeFor(PMIC_INT, FALLING);

    // https://docs.particle.io/reference/asset-tracking/tracker-edge-firmware/#trackersleep
    TrackerSleep::instance().registerSleepPrepare(prepareSleepCallback);
    TrackerSleep::instance().registerWake(wakeCallback);

The callbacks just prints statements to see when they are activated

Here is the test code (there are some more codes but I just extracted the part that we are concerned with on the loop function

    // Must call this on every loop
    Tracker::instance().loop();

    static uint32_t executiontime = millis();
    if(millis()-executiontime>5000 ) // every 5 seconds
    {
        if (!TrackerSleep::instance().isSleepDisabled()) {
            Log.info("Sleep Enabled");  // This never gets called
        }

        Log.info("ExtendExecutionFromNow");
        TrackerSleep::instance().resumeSleep();
        TrackerSleep::instance().extendExecutionFromNow(2, true); // force the sleep within 2 seconds
        TrackerSleep::instance().resumeSleep();
        executiontime = millis();
    }


    if(millis()-recordedmillis>2000 ) // every 2 seconds
    {
        Log.info("Alive");
        recordedmillis = millis();
    }

I am wondering why the “Sleep Enabled” never gets printed. I did set that on the config but it seems the sleep isn’t enabled (I restarted the unit multiple times to ensure that it communicates to the cloud and get the configurations)

It just continues on printing and never sleeps. I guess the sleep is not enabled.

Second is the motion detection. I enabled it on the Tracker Fleet Config, but when I saw the JSON

Highly appreciate any help.

Thanks!

Hi,

I was able to make it work. There is another identical page for the device regarding settings. That’s the one I used instead of the Asset Tracker Fleet settings.

Thanks!
