# dds2mqtt
Here we combine dds with mqtt. So DDS node can communicate with MQTT broker.
DDS node <--local--> NanoSDK client <--network--> NanoMQ Broker
## Requires
Select cyclonedds as dds backend.
+ CycloneDDS version == 0.10.1
NanoSDK is a MQTT SDK.
+ NanoSDK version >= 0.7.5
Note. libddsc and libnng should be installed.
## NOTE
Select topics from configure file is not supported.
## TEST
Step1. Turn on nanomq
Step2. Start the dds2mqtt proxy
```
./dds2mqtt proxy
```
Test msgs from DDS to MQTT
Step3.
```
./nanomq_cli/nanomq_cli sub --url "mqtt-tcp://127.0.0.1:1883" -t "DDS/HelloWorld"
```
Step4.
```
./dds2mqtt pub
```
Test msgs from MQTT to DDS
Step5.
```
./dds2mqtt sub
```
Step6.
```
./nanomq_cli/nanomq_cli pub -t DDSCMD/HelloWorld -m '{
