Question

I see it can work as MQTT broker and publisher, but not as subscriber ... Can it work as MQTT subscriber? Thanks.

Comments

As I am using MQTT differently, it took me some time to find out the philosophy behind the Teltonika MQTT. If I am right, Teltonika MQTT broker acts as a receiver for queries. the corresponding data is then sent out via the publisher. Its not so clear for me about how this is working over internet using 4G and private IP´s.  As long as you are using LAN connections   or  internet with public IPs this might work.  Hopefully Teltonika can show us a way how to setup this most common use case (mobile internet without public IP) and using a hosted MQTT-broker with known fixed IP somwhere in the net.

Hello, 

It is possible to let RUT955 act as a subscriber but it would be on Command Line based. 

To make this work you need to follow the steps below: 

1. Log in to SSH or CLI of RUT955 
2. Execute this command: opkg update
3. After the opkg update is finished execute this: opkg install mosquitto-client
4. Now you can make the RUT955 as a subscriber with mosquitto_sub 

Example: mosquitto_sub -h  192.168.100.1 -t mqtttest

For more information about mosquitto_sub you can refer to this link: mosquitto_sub

I hope it helps.
