arduino_uip do not work every times with mqtt library PubSubClient
I try to use mqtt library PubSubClient with arduino_uip https://github.com/knolleary/pubsubclient this is the ino file:
/*
Basic MQTT example
- connects to an MQTT server
- publishes "hello world" to the topic "outTopic"
- subscribes to the topic "inTopic"
*/
#include <UIPEthernet.h>
// The connection_data struct needs to be defined in an external file.
#include <UIPServer.h>
#include <UIPClient.h>
#include <PubSubClient.h>
// Update these with values suitable for your network.
byte mac[] = { 0xDE, 0xED, 0xBA, 0xFE, 0xFE, 0xED };
byte server[] = { 192, 168, 1, 172 };
byte ip[] = { 192, 168, 1, 6 };
#if UIP_LOGGING == 1
void uip_log(char *msg){
Serial.println(msg);
}
#endif
void callback(char* topic, byte* payload, unsigned int length) {
// handle message arrived
}
EthernetClient ethClient;
PubSubClient client(server, 1883, callback, ethClient);
void setup()
{
Serial.begin(9600);
delay(2000);
Serial.println("Started");
Ethernet.begin(mac, ip);
if (client.connect("arduinoClient")) {
Serial.println("connected");
client.publish("outTopic","hello world");
client.subscribe("inTopic");
}
}
void loop()
{
client.loop();
}
some time it works and I get:
