GCI search & multiple cell location

[barbiz]

Hello,

since location accuracy is not enough for us with single cell, we are trying to use multiple cell location.

We tries with %NCELLMEAS = 2 but we don't get multiple cells. Maybe the serving cell has good signal?

Then we tried with GCI search and fw 1.3.4.

%NCELLMEAS = 3,3

and we got those 3 cells (I added newlines for easiness of reading):

%NCELLMEAS: 0,

"0AAE62A2","22201","92B9",65535,0,6254,243,62,19,178936,0,0,

"0319AFA2","22201","92B8",65535,0,6254,295,62,18,178936,0,0,

"0094586F","22210","69D9",65535,0,6354,105,77,29,178973,0,0

so we tried to inject this data into the nrfCloud API:

{
  "lte": [
    {
      "mcc": 222,
      "mnc": 1,
      "eci": 179200674,
      "tac": 37561,
      "earfcn": 6254,
      "adv": 65535,
      "rsrp": -78,
      "rsrq": -10,
      "nmr": [
        {
          "earfcn": 6254,
          "pci": 295,
          "eci": 52015010,
          "rsrp": -78,
          "rsrq": -10.5
        },{
          "earfcn": 6354,
          "pci": 105,
          "eci": 9721967,
          "rsrp": -63,
          "rsrq": -5
        }
      ]
    }
  ]
}

and this is the response:

{
	"lat": 45.39999247,
	"lon": 11.90999508,
	"uncertainty": 2472,
	"fulfilledWith": "MCELL"
}

which does not give any improvement on the original location with SCELL.

Can you help us? Are we formatting the data the wrong way?

Hi Marco,

Your formatting is correct. What is the device ID? I can look into the logs and see if I can help you get a better result. 

Thanks,

Cole

Actually, I am directly calling the API cloud-to-cloud so there is no device id. How can I make my call trackable?

Also, I was wondering: what is the difference between my formatting and passing an array of cells direcly in the "lte" object?

Hello, any updates?

thanks
