Hi, I am hoping someone can help me.
I have an ESP8266 running ESPBasic. It has a Thingspeak send function and it works like a charm to get data from the IOT device to my channel/field. I want to send this data (using time control) as part of a https:// URL which has the format
Using GET i can successfully send the &value=111 to my.zipato.com as a manual entry so i know the URL works.
How can i replace the &value=xxx so that it contains the actual field value of my channel ?
I tried to replace the manual value with %%channel_1234_field_1%% but this doesnt work.
I would appreciate any suggestions
There is some evidence to suggest that variable substitution doesn't occur in GET requests (where the values are passed in the URL). Is it possible for you to use the POST format instead? Otherwise Vinod's solution looks good if you can find your way around the Matlab syntax.
