MQTT : username & password

[s-muller]

Hello,

I am trying to connect to the MQTT port of the Blynk server with “MQTT Explorer”.

I use a local server configured to respond to MQTT requests on port 8440 :
hardware.mqtt.port=8440

I use the same username and password as for the Android application, however “MQTT Explorer” returns me the error “Connection refused: Bad username or password”.

Am I using the wrong connection parameters? Or is this another problem?

If anyone has an idea, I’m interested.

Thank you in advance.

Steve

Hi,
It seems that the MQTT functionality within Blynk was started but never completed.
There is some info here…

Sending MQTT message to blynk

Hi! I am using local blynk server (server-0.41.15.jar). I was able to send mqtt message to blynk: mosquitto_pub -h <IP> -p 8440 -t “hardware” -u <UID> -P <TOKEN> -m “dx 2 0”. It update the relevant pin on the app side (in this case digital_pin_2 will be 0 on app side), but does not update on the device side. It is possible to send the relevant message also to the device? Thank, Tamás

I use MQTT for communication with all my Home Automation devices, but use Node-Red and the Blynk-ws-contrib for Node-Red to hanlde the communication with the Blynk server via websockets.
This works very well.

Pete.
