Why am I getting does not name a type for IPAddress and Serial? I want an ESP8266 to pass through serial int data from an Uno to UDP packets to send to another ESP8266.
int code, x;
IPAddress ip(192, 168, 1, 139);
const char* ssid = "JMR";
const char* password = "crystal2965";
#include <SPI.h> // needed for Arduino versions later than 0018
#include <Ethernet.h>
#include <EthernetUdp.h> // UDP library from: bjoern@cs.stanford.edu 12/30/2008
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
WiFi.mode(WIFI_STA);
WiFi.config(192, 168, 1, 137);
WiFi.begin(ssid, password);
Serial.println("");
// Wait for connection
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.print("Node7b: Connected to ");
Serial.println(ssid);
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
unsigned int localPort = 8888; // local port to listen on
// buffers for receiving and sending data
char packetBuffer[UDP_TX_PACKET_MAX_SIZE]; //buffer to hold incoming packet,
// An EthernetUDP instance to let us send and receive packets over UDP
EthernetUDP Udp;
void setup() {
// start the Ethernet and UDP:
Udp.begin(localPort);
Serial.begin(115200);
}
void loop() {
if (Serial.available) {
code = Serial.read();
// send a reply, to the IP address and port that sent us the packet we received
x = Udp.beginPacket(ip, 8888);
Serial.print("Packet status: "); Serial.print(x);
Serial.print("Sent: "); Serial.print(code);
Udp.write(code);
Udp.endPacket();
}
delay(100);
}
