MQTT-SN Java Gateway and Client now contributed to Paho

[Ian Craggs]

Hello all,

I've just added three MQTT-SN components to Paho, in the

git.eclipse.org/c/paho/org.eclipse.paho.mqtt-sn.apps.git

directory.  This is MQTT-SN code that was written in IBM Zurich around 2008 when the MQTT-SN (or MQTTS) specification was being drawn up.  It consists of:

1. A Java MQTT-SN to MQTT gateway (MQTTSN-Gateway)
2. A java MQTT-SN client (MQTTSN-UDP-Client)
3. A C MQTTSN-C-Client (MQTTSN-C-Client)

The Java gateway and client work as they are -- I tried them out today.

The C client is a framework which has a network layer which needs completion to work.  I haven't tried that out.  In any case, I expect it to be superseded by the MQTT-SN C/C++ embedded clients of which I have completed the first layer (in http://git.eclipse.org/c/paho/org.eclipse.paho.mqtt-sn.embedded-c.git/). That is, unless anyone finds a particular use for it.

Have anyone tried MQTT-SN to MQTT gateway (MQTTSN-Gateway)

in production maybe

i have seen alarming TODO-s in the source code

Hi,

this code is meant to be used as a basis for enhancement or an idea of how to implement a gateway.  It's not meant to be production ready at this point.
