Using {port} in the Publish Uplinks field of MQTT Connector

[edulbastos]

Hi,

When using {port} in the Publish Uplinks field of MQTT Connector, the {port} is not translated to the specific port (the port parameter is in the uplink field) and I don´t receive any message in the MQTT server. I want to separate different ports to differents topics in the MQTT servers. Any hints?

Regards,

Hello, can you show me how are you using this parameter? Passing port field by default (in the Fields parameter) works fine.

I have the same issue. I'm not receiving any MQTT topics when publish uplinks parameter includes {port}. All works fine when {port} is removed. My handlers "Parse Uplink" is default (empty).

Hello, can you share your handler and connector configuration, so I may have a look on what is going wrong?

Hi @altishchenko,

Sorry about the delay. I´m using {port} after the published topic. Ex: (in the Publish Uplinks field):

TTGO/{port}

But I´m not receiving any MQTT topic with port attached at the end. The attribute port is in the Uplink Fields.

Hi @altishchenko,

The screenshots of my Handler and Connector configuration are as follow:

My settings for handler: downlink_expires = "never"; event_fields = ("app", "event", "appid", "devaddr", "appargs", "datetime", "deveui", "port"); payload = "custom"; uplink_fields = new JArray("port", "app", "data", "datetime", "deveui", "desc", "freq", "codr", "datr", "fcnt");

Connector: auth = "normal"; enabled = true; format = "raw"; publish_qos = 0; publish_uplinks = @"{app}/{port}"; publish_events = @"{app}/events"; received = @"{deveui}/tx"; subscribe = "+/tx"; subscribe_qos = 0; uri = "mqtt://127.0.0.1:1883";

All other fields are empty (default).
