Hi, I want to build arduino with 2 servers.
one of them is for web service to change IP address from the web page(port 80)
second server is for snmp agent protocol to send temperature to the MIB manager (port 161)
both of them works great when they are not mixed with each other
but when I want to use both of them none of them works! is it possible to do this?
this is part of my code:
#include "SnmpAgent.h"
#include <TextFinder.h>
#include <EEPROM.h>
#include <avr/pgmspace.h>
#include <UIPEthernet.h>
#include <OneWire.h>
#include <DallasTemperature.h>
#include <SimpleTimer.h>
SNMPAgent SnmpAgent;
OneWire oneWire(2);
DallasTemperature Sensors(&oneWire);
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
byte ip[] = {192,168,1,15};
byte subnet[] = {255,255,255,0};
byte gateway[] = {192,168,1,1};
byte dnsserver[] = {192,168,1,1};
EthernetServer server(80);
EthernetServer server2(161);
void setup() {
ShieldSetup();
Sensors.begin();
server.begin();
server2.begin();
// Setup default SNMP Agent information
SnmpAgent.SetCommunity(PSTR("public")); // Password/Community (Read-Only)
SnmpAgent.SetDescription(PSTR("Force Sensor")); // 1.3.6.1.2.1.1.1.0
SnmpAgent.SetContact(PSTR("vader@deathstar.com")); // 1.3.6.1.2.1.1.4.0
SnmpAgent.SetLocation(PSTR("Death Star")); // 1.3.6.1.2.1.1.6.0
SnmpAgent.SetSystemName(PSTR("arduino")); // 1.3.6.1.2.1.1.5.0
// Setup custom SNMP values (1.3.6.1.4.1.49701.1.X.0),
// where X is a value between 1 and 5 (defined by MAX_SNMP_VALUES in SnmpAgent.h)
SnmpAgent.SetValue(1, temperature); // 1.3.6.1.4.1.49701.1.1.0
SnmpAgent.SetValue(2, &lastMillis); // 1.3.6.1.4.1.49701.1.2.0
