MQTT BROKER - NO CONNECTION

[RaulSuquinagua]

Hi, I have implemented the code with wifi modules esp8266, NODE.JS SERVER in Linux Mint and using "mosquitto" as MQTT BROKER, but I get the following error:

[MESH >>] {"topic":"2483256220/water","payload":"275"}
[ERROR] No MQTT connection

This is the configuration of the "config.js" file:

config.serial = {};
config.serial.port = process.env.MESH_SERIAL_PORT || "/dev/ttyUSB0"; // "/dev/ttyUSB3"
config.serial.baud = process.env.MESH_SERIAL_BAUD || 115200;

config.mqtt = {};
config.mqtt.server = process.env.MESH_MQTT_SERVER_URL || "192.168.1.104:1883";

Hi.
Please try to connect to mqtt server using some test tool like mqttspy or mqttlens and then try simple command line:

mosquitto_pub -h 192.168.1.104 -p 1883 -t "hello"  -m "MQTT test"

There is a simple case in my code - if underlying mqtt library can't connect - i show this message.
