how to send data to firebase and also receive data using matlab
I want to send data from some variables to the firebase database and then I also want to receive this data, I used this code:
% Load the Firebase credentials
firebaseCredentials = jsondecode(fileread(‘path/to/firebase_credentials.json’)); %I exchanged this for my data
% Specify the Firebase URL and the data to send
firebaseURL = ‘https://your-firebase-project.firebaseio.com/’; %I exchanged this for my data
data = struct(‘current’, 10, ‘voltage’, 220); % Replace with your actual sensor data
% Encode the data as JSON
jsonData = savejson(”, data);
% Create the HTTP request options
options = weboptions(‘RequestMethod’, ‘post’, ‘HeaderFields’, {‘Content-Type’ ‘application/json’}, ‘Timeout’, 10);
% Send the data to Firebase
response = webwrite([firebaseURL ‘.json’], jsonData, options);
But whenever I send data it creates a new node, but I wanted it to replace the information that was already there in a specific node, because later I want to use an application that I created to read these values in Firebase and create another variable in the same node that will be used to send data to change variable data in Matlab, and now if you could also help me with how to read the node that It’s in Firebase through Matlab and writing it in a variable would be appreciatedI want to send data from some variables to the firebase database and then I also want to receive this data, I used this code:
