asset tracker not updating the gps values

[Muhammad Usman]

Hi All , 

I am using nrf9160Dk ,When i use asset tracker V2 i successfully get the GPS values on the nrf Cloud . But when i use the Asset Tracker only then i am unable to get the GPS values.

these are the values i get on the terminal . 

"Received":{

"appId":

"RSRP"

"data":

"messageType":

Can you please help me in this regard ? Do we have to set some configuration in kconfig or .config ?

Thanks & Regards

Hi All! 

I have one more observation while working with nrf9160Dk and the Asset Tracker V1.

When I pressed button # 1 for 10 Seconds I got the following string into my nrf cloud terminal.

"Received":{3 items
"appId":"AGPS"
"messageType":"DATA"
"data":{6 items
"mcc":334
"mnc":20
"tac":5146
"eci":38360578
"rsrp":-140
"types":[8 items
0:1
1:2
2:3
3:4
4:6
5:7
6:8
7:9
]
}
}

After that, I waited for 5 mins but still no GPS update on the Location window. After that, I move the nrf9160DK a little bit almost half meter. then it updated the following string on the terminal

"Received":{4 items
"appId":"GPS"
"data":"$GPGGA,XXXXXX.16,2034.37917,N,XXXXX.XXXXX,W,1,04,4.06,1570.26,M,,M,,*5E
"
"messageType":"DATA"
"ts":1645377692091
}

And it also updated my current location on the Location window of nrf cloud! And after that whenever I restart my nrf9160DK it sends the GPS value once and updates it on the map. Means it's working fine!

Can you please tell me? that where I can enable GPS without pressing Button # 1 for 10 seconds and moving the kit. I want it to automatically enable it.

Thanks & regards,

Muhammad Usman

Hello Muhammad,

the Asset Tracker v1 is deprecated. Please use Asset Tracker v2.

Hello Markus,

Thank you so much for the response!

I am using esp32c3 reading sensor values and sending them to nrf9160DK via UART. And nrf9160DK read the values and send them to nrf cloud via LTE. 

My requirement is to read the GPS values and RSSI from the nrf9160 as well. For me, it's difficult to make changes in the asset tracker v2 as compared to v1. Asset tracker v1 is similar to the cloud client app.I did my task with the cloud client.

Can you please recommend me asset tracker V1 or v2 ? as I mentioned my requirements. Will it be problematic for me in the future?

If you recommend asset tracker v2 is there any programming guidelines other than this

In general, our recommendation is to use the Asset Tracker v2. Asset Tracker v1 is not available anymore from NCS version 1.9.0 neither.

Then of course I get your point, that using v1 as a starting point for own application development can be more convenient due to reduced complexity. But please note that v1 does not support all features that are implemented in v2.

The Asset Tracker v2 is build on modules, making it possible to exclude the ones you are not intending to use. This should reduce complexity at least a little bit.
