MY_GATEWAY_MQTT_CLIENT

[keithJ]

Hi,

I am trying to setup a MQTT (client) ethernet gateway using an UNO R3, W5100 ethernet shield, and Adafruit RFM69HCW.

The nodes are communicating well with gateway using #define MY_GATEWAY_W5100; but I am having no luck when i change it to #define MY_GATEWAY_MQTT_CLIENT, and am getting the following error :

34779 GWT:TPC:IP=192.168.1.177
35781 GWT:RMQ:CONNECTING...
37785 !GWT:RMQ:FAIL

// Enable gateway ethernet module type
//#define MY_GATEWAY_W5100
#define MY_GATEWAY_MQTT_CLIENT

// Set this node's subscribe and publish topic prefix
#define MY_MQTT_PUBLISH_TOPIC_PREFIX "mygateway1-out"
#define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "mygateway1-in"

// Set MQTT client id
#define MY_MQTT_CLIENT_ID "mysensors-1"

#define SD_SS_PIN (4)  // chip-select for SD card (normally unused, pull high!, see code!) 

// Enable these if your MQTT broker requires username/password
//#define MY_MQTT_USER "username"
//#define MY_MQTT_PASSWORD "password"

// Enable MY_IP_ADDRESS here if you want a static p address (no DHCP)
#define MY_IP_ADDRESS 192,168,1,177   // If this is disabled, DHCP is used to retrieve address
#define MY_MAC_ADDRESS 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED

// If using static ip you can define Gateway and Subnet address as well
#define MY_IP_GATEWAY_ADDRESS 192,168,1,1
//#define MY_IP_SUBNET_ADDRESS 255,255,255,0

// MQTT broker ip address or url. Define one or the other.
//#define MY_CONTROLLER_URL_ADDRESS "m20.cloudmqtt.com"
#define MY_CONTROLLER_IP_ADDRESS 192, 168, 1, 225

// The MQTT broker port to to open
//#define MY_PORT 1883

I can connect to the MQTT broker (which is my openhab instance on 192.168.1.225)
without username and password)

I have read lots but become even more confused :/

In addition to #define MY_GATEWAY_MQTT_CLIENT, what else should be set? How can i see if there is even an attempt to contact the broker?

many thanks

OMG!!! i feel such a fool!

Spent a good hour searching - and immediately after posting the above - realised the ethernet cable was unplugged!!!!

facepalm!

:blush:

[keithJ]

actually it was longer than that :/

This is a good tip to add to the build instructions. Check if you plugged the cable 😂
