Format for GPS geopoint

Question

I'm sure this should be really simple to find but i can't see this info anywhere.

What is the required format for the location property on Iot Central? I can see it is geopoint but i have formatted my data as per the below and this doesn't work:

"gps":"lat: 53.065151, lon: -2.478252"

gps in the data handle, i can see the data is sat against the correct data handle in raw data but none of the map tiles are working so i am presuming i have the wrong format?

Answer 1

I believe it expects and object with lat and lon properties, not a string. For example:

"devicelocation": { "lat": 53.065151, "lon": -2.478252 }

Answer 2

I’ve spent most of the day trying to debug this and it’s bizarre, i think i’ve now managed to get everything in the right place but i still get blank maps “Awaiting Data”. I have tried both with and wihout lat: lon: and that made no difference. I don’t really know who to ask as Microsoft don’t appear to offer any kind of support? Any ideas welcome!

My code to get to this point is (summarised a little):

location_format =(String(GPS.latitudeDegrees) + "," + String(GPS.longitudeDegrees));
createEventPayload(27,location_format,longi,lati);

void createEventPayload(int temp, String location_format, float longi, float lati)
{
temp=32;
JsonWriterStatic<256> jw;
{
JsonWriterAutoObject obj(&jw);
jw.insertKeyValue("temp", temp);
jw.insertKeyValue("gps", location_format);

}
Particle.publish("Test_data", jw.getBuffer(), PRIVATE);
Serial.println("Sent Test Data");
Serial.println(jw.getBuffer());

}
