Can't connect

Need Help With My Project
1

Hi All,

I’m having problems connecting to the blynk servers.

When I attempt to use my wifi shield it just repeats “Connecting to cloud.blynk.cc:8442” over and over again. When I run telnet cloud.blynk.cc 8442 the cmd box says connecting… then goes blank with a blinking cursor.

When I try to connect with the Arduino_Serial_USB sketch, the serial monitor just repeats my Auth Token over and over again on the same line.

Any help would be greatly appreciated. Thanks!

If telnet doesn’t work, problem is in the router (or PC firewall). Check that Windows firewall doesn’t block 8442 port and check same for your router.

Telnet does work. I end up in Telnet cloud.blynk.cc after command.

Okay, I got it to work following these steps:

but this really didn’t work, the .elf files have to be in the Flip directory, so I followed the advice on this forum:

I always received the “WARNING: The user program and the bootloader overlap!” but that didn’t seem to matter.

After the wifi shield firmware was up to date, the ConnectWithWPA example sketch still tells you to “Please Upgrade the firmware” so add serial.printin(fv) to know what firmware version you are on. like so:

String fv = WiFi.firmwareVersion();
if ( fv != “1.1.0” )
Serial.println(“Please upgrade the firmware”);
Serial.println(fv);

Don’t forget to remove the jumper and reset the wifi shield. Then change:

// Your WiFi credentials
char ssid = “my NetworkName is there”;
char pass = “my Password is there”; // Set to “” for open networks
IPAddress server_ip (45,55,195,102);

void setup()
{
Serial.begin(9600);
//Blynk.begin(auth, ssid, pass);
// Or specify server using one of those commands:
//Blynk.begin(auth, ssid, pass, “server.org”, 8442);
Blynk.begin(auth, ssid, pass, server_ip, 8442);
}
IPAddress server_ip (45,55,195,102);

per these instructions:
