Hi,

Hardware: NOTE-NBGL-500 and Notecard AA.  
Notecard Firmware: 8.1.3.17044

I have set up the Notecard to function as asset tracker using these commands.  
{“req”:“hub.set”, “product”:“com.gmail.robregadomarkel:cellular\_legacy”, “mode”: “periodic”, “outbound”: 5}  
{“req”: “card.wireless”, “apn”: “http.globe.com.ph”}  
{“req”: “card.location.mode”, “mode”: “periodic”, “seconds”: 60}  
{“req”: “card.location.track”, “start”: true}

It does connect to Notehub. I power the Notecard and Notecarrier using 3 x AA batteries. Then I placed it in a box. I walked around my place for 23 minutes. I came back to my place and checked Notehub. There is only 1 \_track.q0 in 23 mins of walking. I am walking so the Notecard should detect movement.

I am following this [youtube video](https://www.youtube.com/watch?v=MVYVVkgdDC4) by TJ.

According to the video guide there should be \_track.q0 every 1 minute at Notehub.

How do I make this work?

I did place the Notecard and Notecarrier in a small cardboard box, then I walked around my area for 23 mins.

Regards,  
Markel

Hi @mtrobregado,

It’s actually the same issue as you reported [in this thread](https://discuss.blues.com/t/notecard-cellular-note-nbgl-500-and-notecarrier-aa-asset-tracker-not-working/2880):

{“req”:“hub.set”, “product”:“com.gmail.robregadomarkel:cellular\_legacy”, “mode”: “periodic”, **“outbound”: 5** }

and

{“req”: “card.location.mode”, “mode”: “periodic”, **“seconds”: 60** }

You’re asking the Notecard to ascertain its location AND connect to a cell network at virtually the same time (which it’s not able to do). You must increase the values on these considerably to use both cell and GPS together.

Thanks,  
Rob

Hi Rob,

I followed TJ youtube video. [How to Build a Fully Functional GPS Asset Tracker in Ten Minutes](https://www.youtube.com/watch?v=MVYVVkgdDC4)

I set the commands same as TJ youtube video.  
{“req”:“hub.set”, “product”:“com.gmail.robregadomarkel:cellular\_legacy”, “mode”: “periodic”, “outbound”: 5}  
{“req”: “card.location.mode”, “mode”: “periodic”, “seconds”: 60}

I don’t understand why I am not getting similar results with same commands. Also, if you watch the video the outbound is set to 5 minutes, but there is \_track.q0 file every less than 5 minutes.

I tested again with these parameters below.  
{“req”:“hub.set”, “product”:“com.gmail.robregadomarkel:cellular\_legacy”, “mode”: “periodic”, “outbound”: 10}  
{“req”: “card.wireless”, “apn”: “http.globe.com.ph”}  
{“req”: “card.location.mode”, “mode”: “periodic”, “seconds”: 120}  
{“req”: “card.location.track”, “start”: true}

I doubled the outbound and seconds from previous testing. I tested for 32 minutes from 6:42 AM to 7:14 AM. I received 3 \_track.q0 at Notehub.

 ![image](https://us1.discourse-cdn.com/flex020/uploads/blues/original/2X/e/eaa80d2bd2cf5340eb6a86098e174ed9d3f0e43f.png)

Here are all three \_track.q0 GPS coordinates.

first \_track.q0:  
“best\_location\_type”: “gps”,  
“best\_location\_when”: 1740956303,  
“best\_lat”: 14.406422500000001,  
“best\_lon”: 120.96319140625,  
“best\_location”: “Imus”,  
“best\_country”: “PH”,

second \_track.q0:  
“best\_location\_type”: “gps”,  
“best\_location\_when”: 1740956313,  
“best\_lat”: 14.406522500000001,  
“best\_lon”: 120.96337890625,  
“best\_location”: “Imus”,  
“best\_country”: “PH”,

third \_track.q0:

“best\_location\_when”: 1740956319,  
“best\_lat”: 14.406547499999999,

Hi Rob,

I entered the three GPS coordinates at Google Map. Here is [link](https://www.google.com/maps/dir/14.4064225,120.9631914/Mambog+III,+Bacoor,+Cavite/TVH+Milktea+and+Lemonade+Hub,+Open+field,+Sampaloc+compound,+Citta+Italia+Subd,+Bacoor,+Cavite/@14.4066313,120.9628084,105m/data=!3m1!1e3!4m15!4m14!1m0!1m5!1m1!1s0x3397d24ab56161bd:0xefc93bce65f6059f!2m2!1d120.9631028!2d14.4064778!1m5!1m1!1s0x3397d370cbb2341b:0x57f1784036c03bb6!2m2!1d120.9634117!2d14.4066631!3e2?entry=ttu&g_ep=EgoyMDI1MDIyNi4xIKXMDSoASAFQAw%3D%3D).

I walked for 32 minutes and I got three GPS coordinates. The distance from first to third GPS coordinates is about 25 meters. It assume walking it took me about 40 seconds to walk 25 meters. If the outbound is set to 10 minutes, why do I get three \_track.qo files in less than 10 minutes? Is it triggered by movement?

Markel

Hey @mtrobregado,

When viewing your `_track.qo` events in Notehub it’s usually more helpful to switch the “Uploaded” column to “Captured”. Captured is the time the Note was created on the Notecard, and Uploaded is the time that Note was uploaded to Notehub. In your screenshot the three `_track.qo` events have nearly identical timestamps because they were uploaded in the same sync.

As for why you only have three events—you are using a narrowband Notecard which can take a long time to make a cellular connection, especially its initial one. (I was using a wideband Notecard in my video.) Plus, getting an initial GPS/GNSS fix can also take a non-trivial amount of time. My guess is that for a large portion of your walk you were waiting for both the initial cellular connection and initial GPS fix.

Can you check the `when` field of your three `_track.qo` events, and let us know if they’re towards the start or end of your walk?

Thanks,  
TJ

If location data is more important than the cadence of syncing the data with the cloud, I would encourage you to use the extensive flash memory available on the Notecard and store as many Notes as possible before syncing. For example:

Change your outbound to once/hour:

```auto
{“req”:“hub.set”, “product”:“com.gmail.robregadomarkel:cellular_legacy”, “mode”: “periodic”, “outbound”: 60}

```

Change your GPS mode to continuous (because `seconds` \< 300 is effectively the same as continuous mode anyway):

```auto
{“req”: “card.location.mode”, “mode”: “continuous”}

```

</div>

If you’re not working with other data, I’d still set a `seconds` as it determines how often the Notecard will create `_track.qo` Notes.

```json
{"req":"card.location.mode","mode":"periodic","seconds":300}

```

Before you try this again, I’d also make sure your Notecard is outside with a clear view of the sky for several minutes before you start your walk. This will help make sure the Notecard can make an initial GPS fix that should get you more reliable readings.
