Hello,

1. TRB142 does have an MQTT broker and publisher feature, you can read more about MQTT configuration in TRB142: https://wiki.teltonika-networks.com/view/TRB142_MQTT

2. RS232 data can be sent using Data to server feature that is available in TRB142. Data to server supports HTTP and MQTT protocols. More about configuration: https://wiki.teltonika-networks.com/view/TRB142_Data_to_Server

3. Answered on the first point. When you configure TRB142 as a broker it can subscribe to specific topics.

4. Unfortunately, data cannot be sent using MQTT to a device connected via RS232 to TRB142. 

Best regards.
