It seems that you have a Location metadata type called Location, and have added a Coordinates metadata type also called Location, which has no coordinate values in it.
Did you add some coordinates, and did you change your sketch to reflect the new name?
Pete.
Yes sir tried
if not possible,
tell m how t read it using http api
@VIGHNESHNS2008 do you have some data assigned to the location metafield of the specific device?Do you get some response at all? Or you get empty response?
yes assigned value.
empty response
@Dmitriy I’ve been doing a bit of testing, and ther seems to be an issue with coordinates…
Metadata setup:
Map Coordinates is populated as follows:
Test code…
BLYNK_CONNECTED()
{
// Send requests for different metadata
Blynk.sendInternal("meta", "get", "Board Type");
Blynk.sendInternal("meta", "get", "Device Location");
Blynk.sendInternal("meta", "get", "Map Coordinates");
}
BLYNK_WRITE(InternalPinMETA) {
String field = param[0].asStr();
if (field == "Board Type")
{
String value = param[1].asStr();
Serial.print("Board Type = ");
Serial.println(value);
}
if (field == "Device Location")
{
String value = param[1].asStr();
Serial.print("Device Loaction = ");
Serial.println(value);
}
if (field == "Map Coordinates")
{
String value = param[1].asStr();
Serial.print("Map Coordinates = ");
Serial.println(value);
}
}
Serial Output…
[2652] Connecting to blynk.cloud:443
[3529] Certificate OK
[3540] Ready (ping: 10ms).
Board Type = ESP32 DevBoard
Device Loaction = The desk in my office
Map Coordinates =
Note that Map Coordinates is blank (or 0.00 if I change to Float).
I also tried param[2].asStr() and param[3].asStr() in the hope that Latitude and Longitude were hidden in there, but no joy.
Also, when you view the Device metadata, the field names are capitalised…
which could get confusing.
Pete.
I tried writing values. Wks fine. but reading is a problem
Same Issue for Me
Yes. You’re right. Not all fields yet supported. I forgot about that. I’ll fix this.
ok.
And… has that unexpeted error fixed?
@VIGHNESHNS2008 location meta reading should work now. Please check.
Yes. Do you still see any errors?
Ok, wil try in some time and reply
Getting only lattitude
no longitud, text, state, zip etc.
Edit: Sorry Mistake
How do you read the data?
Could you please show it?
From device
By the way I am reading the prebuilt location metadata.
ANy clues?
Please show your code… Otherwise i can only guess.

@VIGHNESHNS2008 please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
```
Pete.
So you read the first param lon, in order to read the next one you need to use param[2].asStr(). Right only lon/lat is supported. It was done for one of the clients. I’ll check if can attach more data.
