MQTT-SN Transparent / Aggregating 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 aggregating Gateway by specifying the gateway.conf.
### **step1. Build the gateway**
````
$ git clone -b develop https://github.com/eclipse/paho.mqtt-sn.embedded-c
$ cd paho.mqtt-sn.embedded-c/MQTTSNGateway
# MQTT-SN Transparent / Aggregating 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 aggregating Gateway by specifying the gateway.conf.
### step1. Build the gateway
copy and expand source code then,
```
$ cd paho.mqtt-sn.embedded-c/MQTTSNGateway
```
In order to build a gateway, one sensor network argument is required.
```
$ ./build.sh [udp|udp6|xbee|loralink|rfcomm]
````
In order to build a gateway, an argument is required.
MQTT-SNGateway and MQTT-SNLogmonitor (executable programs) are built in the Build directory.
### **step2. Execute the Gateway.**
```
````
MQTT-SNGateway and MQTT-SNLogmonitor (executable programs) are built in ./bin directory.
### step2. Execute the Gateway.
```
$ cd bin
$ ./MQTT-SNGateway
````
$ ./MQTT-SNGateway
```
If you get the error message as follows:
````
RingBuffer can't create a shared memory.
ABORT Gateway!!!
````
RingBuffer can't create a shared memory. ABORT Gateway!!!
You have to start using sudo command only once for the first time.
````
$ sudo ./MQTT-SNGateway

```
$ sudo ./MQTT-SNGateway

## Contents of the gateway configuration file
**gateway.conf** is in bin directory. It's contents are follows:

**GatewayID** is a gateway ID which used by GWINFO message.
**GatewayName** is a name of the gateway.
**MaxNumberOfClients** is a maxmum number of clients. Clients are dynamically allocated.
**KeepAlive** is KeepAlive time in seconds.
**LoginID** is used by CONNECT message.
**Password** is used by CONNECT message.
**BrokerName**is a domain name or IP address of a broker.
**BrokerPortNo** is a broker's port no.
**BrokerSecurePortNo** is a broker's port no of TLS connection.
```
#
# CertsKey for TLS connections to a broker

#RootCApath=/etc/ssl/certs/
#CertsKey=/path/to/certKey.pem

```
**RootCAfile** is a CA file name.
**RootCApath** is a CA path. **SSL_CTX_load_verify_locations(ctx, CAfile, CApath)** function requires these parameters.
**CertsKey** is a certificate pem file.
**PrivateKey** is a private key pem file.
Clients can connect to the broker via TLS by setting '**Secure Connection**' for each client in the client conf file.
```

```
The gateway runs as a aggregating gateway when **AggregatingGateway** is 'YES'.
If **QoS-1** is 'YES, the gateway prepares a proxy for the QoS-1 client.　QoS-1 client has a 'QoS-1' parameter in a clients.conf file.　For QoS-1 clients, set the QoS-1 parameters in the clients.conf file.
If **Forwarder** is 'YES', the gateway prepare a forwarder agent.
If **ClientAuthentication** is 'YES', the client cannot connect unless it is registered in the clients.conf file.
**ClientsList** defines clients and those address so on.
**PredefinedTopicList** file defines Predefined Topic.

**GatewayPortNo** is a unicast port no of the gateway.
**MulticastIP** and **MulticastPortNo** are for GWSEARCH messages. Clients can get the gateway address (Gateway IP address and GatewayPortNo) from GWINFO message by means of std::recvfrom().
Client needs to know the MulticastIP and MulticastPortNo to send a SEARCHGW message.
**MulticastTTL** is a multicast TTL.

**BrokerName** to specify a domain name of the Broker, and **BrokerPortNo** is a port No of the Broker. **BrokerSecurePortNo** is for TLS connection.
**MulticastIP** and **MulticastPortNo** is a multicast address for GWSEARCH messages. Gateway is waiting GWSEARCH and when receiving it send GWINFO message via MulticastIP address. Clients can get the gateway address (Gateway IP address and **GatewayPortNo**) from GWINFO message by means of std::recvfrom().
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 **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.
When **Forwarder** is **YES**, Forwarder Encapsulation Message is available. Connectable Forwarders must be declared by a **ClientsList** file.
**MaxNumberOfClients** Maximum number of clients allocated.
### ** How to monitor the gateway from remote. **
### How to monitor the gateway from a remote terminal.
Change gateway.conf as follows:
```
# LOG
ShearedMemory=YES;
````
Restart the gateway with sudo only once to create shared memories.
```
Restart the gateway with sudo only once to create shared memories.
open ssh terminal and execute LogMonitor.
```
$ cd bin
$ ./MQTT-SNLogmonitor
```
```
Now you can get the Log on your terminal.
## ** Tips **
Uncomment the line 62, 63 in MQTTSNDefines.h then you can get more precise logs.
##### Tips
Use compiler definitions then you can get more precise logs.
**-DDEBUG_NW** is a flag for debug logs of Sensor network.
**-DDEBUG_MQTTSN** is a flag for debug logs of MQTT-SN message haandling.
One or both flags can be specified.
```
./build.sh udp -DDEBUG -DDEBUG_NW
```
/*=================================
* Log controls
==================================*/
//#define DEBUG // print out log for debug
//#define DEBUG_NWSTACK // print out SensorNetwork log
