So, I want the boron to read data from a web page to configure itself when it wakes up. I understand that normally variables or functions could be use for this, but in my configuration the boron is mostly sleeping. Having a particle.function or variable called when it wakes up to reconfigure a parameter is unreliable.
I would like the boron to actively read the page when it wakes up, rather than have something outside the boron tickle the function block. This seems like a simple thing, but there is nothing that I can find that fits the bill.
I did find someone who posted this code below, which I will try. But I would have thought particle would have a library function for doing this as it seems pretty basic. If someone has a recommendation please let me know. Thanks.
String host = "toptalkback.com";
const int serverPort = 80;
String DownloadJson(String url){
String output;
if(client.connect(host, serverPort)) {
client.println("GET "+url+" HTTP/1.0");
client.println("Host: " + host);
client.printlnf("Content-Length: %d", 2);
client.println("Content-Type: application/json");
client.println();
client.flush();
delay(5000);
while(client.available()) {
char c = client.read();
output = output + c;
}
}
return output;
}
Thanks for any feedback or suggestions.
