**esp_mqtt**
==========
This is MQTT client library for ESP8266, port from: [MQTT client library for Contiki](https://github.com/esar/contiki-mqtt)
**Features:**
* Support subscribing, publishing, authentication, will messages, keep alive pings and all 3 QoS levels (it should be a fully functional client).
* Support multiple connection (to multiple hosts).
* **Support SSL connection (max 1024 bit key size)**
* Easy to setup and use
**Usage**
```c
#include "ets_sys.h"
#include "driver/uart.h"
#include "osapi.h"
#include "mqtt.h"
#include "wifi.h"
#include "config.h"
#include "debug.h"
#include "gpio.h"
#include "user_interface.h"
MQTT_Client mqttClient;
void wifiConnectCb(uint8_t status)
{
if(status == STATION_GOT_IP){
MQTT_Connect(&mqttClient);
MQTT_Subscribe(&mqttClient, "/test/topic");
MQTT_Subscribe(&mqttClient, "/test2/topic");
}
}
void mqttConnectedCb(uint32_t *args)
{
MQTT_Client* client = (MQTT_Client*)args;
INFO("MQTT: Connected\r\n");
}
void mqttDisconnectedCb(uint32_t *args)
{
MQTT_Client* client = (MQTT_Client*)args;
INFO("MQTT: Disconnected\r\n");
}
void mqttDataCb(uint32_t *args, const char* topic, uint32_t topic_len, const char *data, uint32_t lengh)
{
INFO("MQTT topic: %s, data: %s \r\n", topic, data);
}
void user_init(void)
{
uart_init(BIT_RATE_115200, BIT_RATE_115200);
os_delay_us(1000000);
CFG_Load();
MQTT_InitConnection(&mqttClient, sysCfg.mqtt_host, sysCfg.mqtt_port, SEC_SSL);
MQTT_InitClient(&mqttClient, sysCfg.device_id, sysCfg.mqtt_user, sysCfg.mqtt_pass, sysCfg.mqtt_keepalive);
MQTT_OnConnected(&mqttClient, mqttConnectedCb);
MQTT_OnDisconnected(&mqttClient, mqttDisconnectedCb);
MQTT_OnData(&mqttClient, mqttDataCb);
WIFI_Connect(sysCfg.sta_ssid, sysCfg.sta_pwd, wifiConnectCb);
INFO("\r\nSystem started ...\r\n");
}
```
**Default configuration**
See: *user_config.h* and *config.c*
**Create SSL Self sign**
```
openssl req -x509 -newkey rsa:1024 -keyout key.pem -out cert.pem -days XXX
```
**SSL Mqtt broker for test**
```javascript
var mosca = require('mosca')
var SECURE_KEY = __dirname + '/key.pem';
var SECURE_CERT = __dirname + '/cert.pem';
var ascoltatore = {
//using ascoltatore
type: 'mongo',
url: 'mongodb://localhost:27017/mqtt',
pubsubCollection: 'ascoltatori',
mongo: {}
};
var moscaSettings = {
port: 8440,
stats: false,
backend: ascoltatore,
persistence: {
factory: mosca.persistence.Mongo,
url: 'mongodb://localhost:27017/mqtt'
},
secure : {
keyPath: SECURE_KEY,
certPath: SECURE_CERT,
port: 8443
}
};
var server = new mosca.Server(moscaSettings);
server.on('ready', setup);
server.on('clientConnected', function(client) {
console.log('client connected', client.id);
});
// fired when a message is received
server.on('published', function(packet, client) {
console.log('Published', packet.payload);
});
// fired when the mqtt server is ready
function setup() {
console.log('Mosca server is up and running')
}
```
**Be careful:** This library is not fully supported for too long messages.
**Status:** *Alpha release.*
