I am trying to connect an ESP-13 module (yes, from jaycar) with an Uno. I've figured out the dip switches etc, and I am getting some information from it when I upload the following code:
/*
WiFiEsp example: ConnectWPA
This example connects to an encrypted WiFi network using an ESP8266 module.
Then it prints the MAC address of the WiFi shield, the IP address obtained
and other network details.
For more details see: http://yaab-arduino.blogspot.com/p/wifiesp-example-connect.html

#include "WiFiEsp.h"
// Emulate Serial1 on pins 6/7 if not present
//#ifndef HAVE_HWSERIAL1
//#include "SoftwareSerial.h"
//SoftwareSerial Serial1(6, 7); // RX, TX
//#endif
char ssid[] = "Flip Broadband"; // your network SSID (name)
char pass[] = "jekhuvbn"; // your network password
int status = WL_IDLE_STATUS; // the Wifi radio's status
void setup()
{
// initialize serial for debugging
Serial.begin(115200);
// initialize serial for ESP module
//Serial1.begin(9600);
// initialize ESP module
WiFi.init(&Serial);
// check for the presence of the shield
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("WiFi shield not present");
// don't continue
while (true);
}
// attempt to connect to WiFi network
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to WPA SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network
status = WiFi.begin(ssid, pass);
delay(5000);
}
Serial.println("You're connected to the network");
}
void loop()
{
// print the network connection information every 10 seconds
Serial.println();
printCurrentNet();
printWifiData();
delay(10000);
}
void printWifiData()
{
// print your WiFi shield's IP address
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// print your MAC address
byte mac[6];
WiFi.macAddress(mac);
char buf[20];
sprintf(buf, "%02X:%02X:%02X:%02X:%02X:%02X", mac[5], mac[4], mac[3], mac[2], mac[1], mac[0]);
Serial.print("MAC address: ");
Serial.println(buf);
}
void printCurrentNet()
{
// print the SSID of the network you're attached to
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print the MAC address of the router you're attached to
byte bssid[6];
WiFi.BSSID(bssid);
char buf[20];
sprintf(buf, "%02X:%02X:%02X:%02X:%02X:%02X", bssid[5], bssid[4], bssid[3], bssid[2], bssid[1], bssid[0]);
Serial.print("BSSID: ");
Serial.println(buf);
// print the received signal strength
long rssi = WiFi.RSSI();
Serial.print("Signal strength (RSSI): ");
Serial.println(rssi);
}
In the serial monitor, I get the following:
AT
AT+RST
ATE0
AT+CWMODE=1
AT+CIPMUX=1
AT+CIPDINFO=1
AT+CWAUTOCONN=0
AT+CWDHCP=1,1
AT+GMR
AT+CIPSTATUS
Attempting to connect to WPA SSID: Flip Broadband
AT+CWJAP_CUR="Flip Broadband","jekhuvbn"
Attempting to connect to WPA SSID: Flip Broadband
AT+CWJAP_CUR="Flip Broadband","jekhuvbn"
You're connected to the network
SSID: AT+CWJAP?
AT+CWJAP?
BSSID: 18:F1:45:33:06:D8
AT+CWJAP?
Signal strength (RSSI): -79
AT+CIFSR
IP Address: 0.0.0.0
AT+CIFSR
MAC address: 60:01:94:0F:30:9B
However, I'm stuck from here. My plan is to use it to send some sensor data to a web server. Any pointers as to why I am not able to get an IP address? Any help much appreciated
The exact module I have is:
