Heartbeat not working?

1

I’ve deployed a remote device based on the basic asset tracker for testing purposes. During movement the device is reporting properly however during periods of inactivity I am not getting a heartbeat message? I’ve also tried the same setup on another device locally with the same result? Here is the setup I used:

{
“req”: “hub.set”,
“product”: “myproduct:etc”,
“mode”: “periodic”,
“outbound”: 60,
“inbound”: 720
}

{
“req”: “card.location.mode”,
“mode”: “periodic”,
“seconds”: 1800
}

{  "req":"card.voltage",  "mode":"lipo"}

{  "req":"card.location.track",  "start":true,  "heartbeat":true,  "hours":12,  "file":"_track.qo"}

{
“req”: “card.wireless”,
“method”: “dual-primary-secondary”,
“apn”: “m2m-west.telus.iot”
}

ok my local device does appear to be sending the heartbeat message now. I’m guessing its because I didn’t set sync to be true for card.location.track? If that’s the case then that crucial piece of info was left out of the hackster.io article.

I don’t see the ability to change this on my already deployed remote device. The closest enviornment variable is: _sync_continuous_inbound. but that presumes continuous and not periodic? Is there any way to change this without retrieving the deployed unit?

Hi @Willemb

You are correct, in order for the heartbeat to upload a note to Notehub, the sync parameter should be set to true otherwise, it will sync based upon the periodic outbound sync you have set to 60 minutes.

I had a look through the reserved environment variables (which can be used to update some command remotely) and there’s currently nothing that would allow you to remotely update the sync: true parameter on card.location.track unfortunately.

Is it just the single deployed device that is affected or is it a fleet of devices?

Thanks,
Alex

Thanks Alex. It is just a single deployed device and it was a very rushed, let’s just go for it type of deployment. :sweat_smile: I’m going to do some further testing first and then go visit it in the field next week to make changes. Really I was curious if the blues.com (Rogers) carrier here in Canada would work in the areas where I need it. I did at least discover that Rogers does not work and the outbounds I did receive were all from the secondary sim card I installed which uses Telus. So not a complete loss of a deployment - learned something crucial

Thanks for the clarification! Out of curiosity, regarding your deployment / coverage, which Notecard are you using?

It the Notecard Cell+WiFi (Cat-M).
