Hello. I am doing a Thingspeak project and I am having this issue that is printed out on only one of my MATLAB analyses which is:
Error using matlab.internal.webservices.HTTPConnector/copyContentToByteArray (line 396)
The server returned the status 429 with message "Too Many Requests" in response to the request to URL
Error in readContentFromWebService (line 46)
byteArray = copyContentToByteArray(connection);
Error in webwrite (line 139)
[varargout{1:nargout}] = readContentFromWebService(connection, options);
Error in High humidity (line 8)
result = webwrite(alert_url, jsonmessage, options);
Can I know what this issue means? The rest of my analyses do not have an issue -- only one of them does.

you mention private channels. Are you using thingspeak? I do not know very much about thingspeak

You are making your thingspeak requests too quickly. Bulk requests should not be any less than 15 seconds apart, and if your bulk request is large then you might have to wait extra time.

Bulk Write JSON Data see the Limitations section at the bottom.
The reacts are set to stop triggering erroed code after a few tries to prevent wasteful MATLAB calls.

Hi. Im trying to send data from matlab which is the data from serial monitor from arduino. It is fine until 9th of data and then it stopped and says :
Error using Untitled (line 27)
'Values' must have a maximum of 9 elements, including the timestamp.
My coding is:
clear all
s = serial('com4');
fopen(s);
i = 1;
while(1)
data(i)= str2double(fscanf(s));
plot(data);
title('Temperature Monitoring')
xlabel('Time')
ylabel('Temperature')
pause(15);
i=i+1;
%thingSpeakWrite(1463959,data,'WriteKey','9OUSQA9OXZU0EO4X')
% Generate timestamps for the data
%tStamps = datetime('now')-minutes(9):minutes(1):datetime('now');
channelID = 1463959; % Change to your Channel ID
writeKey = '9OUSQA9OXZU0EO4X'; % Change to your Write API Key
% Write 10 values to each field of your channel along with timestamps
tStamp = datetime('now')
thingSpeakWrite(1463959,data,'WriteKey','9OUSQA9OXZU0EO4X','TimeStamp',tStamp)
end
