# MQTT-SN Transparent / Aggrigating Gateway
**MQTT-SN** requires a MQTT-SN Gateway which acts as a protocol converter to convert **MQTT-SN messages to MQTT messages**. MQTT-SN client over SensorNetwork can not communicate directly with MQTT broker(TCP/IP).
This Gateway can run as a transparent or aggrigating Gateway by specifying the gateway.conf.
### **step1. Build the gateway**

Client should know the MulticastIP and MulticastPortNo to send a SEARCHGW message.
**GatewayId** is used by GWINFO message.
**KeepAlive** is a duration of ADVERTISE message in seconds.
when **AggregateGateway** or **ClientAuthentication** is **YES**, All clients which connect to the gateway must be declared by a **ClientsList** file.
when **AggregatingGateway** or **ClientAuthentication** is **YES**, All clients which connect to the gateway must be declared by a **ClientsList** file.
Format of the file is ClientId and SensorNetwork Address. e.g. IP address and Port No etc, in CSV. more detail see clients.conf.
When **QoS-1** is **YES**, QoS-1 PUBLISH is available. All clients which send QoS-1 PUBLISH must be specified by Client.conf file.
When **PredefinedTopic** is **YES**, **Pre-definedTopicId**s specified by **PredefinedTopicList** are effective. This file defines Pre-definedTopics of the clients. In this file, ClientID,TopicName and TopicID are declared in CSV format.
