Hey guys, I am new to retrieving information from the web, and am trying to run the code from the TCP example from Documentation: // EXAMPLE USAGE TCPClient client; byte server[] = { 74, 125, 224, 72 }; // Google void setup() { Serial.begin(9600); delay(1000); Serial.println("connecting..."…

TCPClient client; byte server[] = { 74, 125, 224, 72 }; // Google void setup() { Serial.begin(9600); delay(1000); Serial.println("connecting..."); if (client.connect(server, 80)) { Serial.println("connected"); client.println("GET /search?q=unicorn HTTP/1.0"); client.printl…

oops, I had no idea that I copied that twice. In my original code, the initialization is done only once! in my serial, it says “connection failed. disconnecting.” I don’t know what is wrong :frowning: Also, when I flash this code, my Spark is unable to flash itself again. I don’t know why that is.…

Maybe this should help :wink: [image] Basic tcp example always returns connection failed on serial [Solved] Firmware Try the following modification. Instead of delaying for 1 second after beginning a serial connection, just s…

Yes! Thank you so much! It works fine after that fix! <3
