I recently bought a TRB145 now I use the latest firmware. I have a Synology Mosquitto MQTT broker and an MQTT Explorer to see the traffic. I have several analog IO-RS485 converters (half duplex) in a loop.
My target to send every RS485 package come from these units to MQTT. and also "ask" these units to send data with special hexa messages back to RS485 through MQTT. So I need a simple two way RS485-MQTT gateway what can handle binary traffic.
I followed the directions to set up MQTT server and publisher. Now I can ask my service provider 100 times with device/get operator command, but
- DATA TO SERVER does not do anything (I maintain active traffic in RS485 different way for testing), no TLS is used, credentials is set up but MQTT is silent (I monitor all the topics the same time with MQTT Explorer)
- RS485 menu item does not have a modem option for MQTT
- MODBUS MQTT GATEWAY: I did not find out how to communicate. Most reponse I get 0 ERROR: INVALID REQUEST. But I guess this is not the RS485 listening what I desire.
Can you please help me?
