Hi Harrison
Thanks for your post.
I don’t have logs at my device, so I really don’t know. My next step would be to reach my computer instead and monitor what comes in.
Yes, it is indeed the SONOS you linked to I’m trying to control. I am able to do it using Fiddler from my PC.
You are right - the &status was a leftover from the twitter example. I have removed it now but the same result remains - nothing.
I’m a software engineer, but I’m a C# / Javascript guy NOT a c++ which is why I’m struggling, hehe. This is y first microcontroller that I have been developing towards in years.
I have tried hitting a webserver on my local PC and have Fiddler running to monitor any traffic - there isn’t any :/.
//Edit - no I don’t mind installing some new software.
I can’t tell if Fiddler can be setup to recieve incoming requests. Any idea? If it can you could try to POST to fiddler and see what comes across.
If Fiddler doesn’t then you could always do a quick install of apache + php and code up a quick php page to dump the incoming request to a file. I’m sure there are faster / cleaner ways but since I do local web dev it would be quickest for me.
Thanks both of yuo, but it didn't solve the issue - still nothing here.
I have tried setting up a webserver and listening on the correct port (with a webservice) - nothing. Is there any other way to figure out if the core is actually transmitting anything? Can I force it to connect through my USB cable using tethering?

Edit - this is how the code looks now:

What happens if you use the example code on the docs?
TCPClient client;
byte server[] = { 74, 125, 224, 72 }; // Google
void setup()
{
// Make sure your Serial Terminal app is closed before powering your Core
Serial.begin(9600);
// Now open your Serial Terminal, and hit any key to continue!
while(!Serial.available()) SPARK_WLAN_Loop();
Serial.println("connecting...");
if (client.connect(server, 80))
{
Serial.println("connected");
client.println("GET /search?q=unicorn HTTP/1.0");
client.println("Host: www.google.com");
client.println("Content-Length: 0");
client.println();
}
else
{
Serial.println("connection failed");
}
}
void loop()
{
if (client.available())
{
char c = client.read();
Serial.print(c);
}
if (!client.connected())
{
Serial.println();
Serial.println("disconnecting.");
client.stop();
for(;;);
}
}
Open up the serial port via usb if you can and look at the serial output of the core.
Great project idea! Would be awesome to integrate this and a hover board to make a sweet remote and you could even have a little screen on it to see whats playing
@krvarma’s code above looks good, but if your having trouble you can also try changing the server to one you create at runscope. then you can see what the core is sending and compare its saved me a bunch of messing around a while back.
Thanks a bunch Krvarma for taking your time. It’s still not working. I will try and setup an URL at runscope tonight and see what’s going on. I don’t think anything is being sent, though :/.
Anyway, here is my full code - is it me having done anything incredibly stupid?
