Unfortunately, this outputs an empty string… After unsuccessfully trying to only retrieve the location field that I’m interested in, I added a text field in the metadata of the Blynk console section called “Test” and tried retrieving that:
This outputs the content of the “Test”-field only. So, is it possible that a “location-type” field in the Blynk console cannot be retrieved on the device? And if so, how can I allow the end user to set the device location in the app and make this information available to my ESP32?
Well, I’ve asked you a question and provided a screenshot, and you’ve replied “yes, I have”.
Some details might be good.
Details of what you get when you try using the REST API to retrieve the data might also be useful, but not if your reply is “same”.
Details of the Metadata IDs that you’ve cropped off of your screenshot might also be helpful.
Basically anything that helps to paint a full picture of what’s happening.
As you can see, there is a value in the field “Test” which I can retrieve without problems. Do you know if it could be a datatype issue? I’m not sure what to expect when retrieving the location field. Is it a string which concatenates adress, zip code and city or is it coordinates?
I’m not actively using REST API so unfortunately I would need to know how to test it if that is an important information.
