App inventor doesnt see the gps data in firebase and its 0 in lat,long

[Z_A]

Hello everyone! I wanted to create the app,that shows arduino gps location from firebase. But ita always 0.000000
using ESP8266(NodeMCU), GPS6MV2
theres a code for arduino
#include <TinyGPSPlus.h>

#include <ESP8266Firebase.h>

#include <ArduinoJson.h>

/*
Note: The latest JSON library might not work with the code.
So you may need to downgrade the library to version v5.13.5

It goes like this

Thanks for help in advance!

That means either your Arduino GPS receiver is not achieving a satellite fix or your script is not sending the value to your Android. 0,0 is the default gps value.

If you code a simpler app, one that does not include Firebase but only posts the data from the Arduino to a Label on the Android, do you get valid location changed values? If you do post valid values, the problem is with your Firebase code; if you do not, the issue is your code that passes the location to your Android.

By the way, your Blocks image is out of focus and not readable
