openwrt-mqtt-sn-gateway

Tested and compiled with Ubuntu 18.04 x86_64.

Build MQTT-SN Gateway

Initialize Environment

We assue you have ~/git directory containing the linux-mqtt-sn-gateway source files.

If not got make:

mkdir -p ~/git
git clone --recursive https://github.com/S3ler/linux-mqtt-sn-gateway.git ~/git/linux-mqtt-sn-gateway
git clone https://github.com/S3ler/openwrt-mqtt-sn-gateway.git ~/git/openwrt-mqtt-sn-gateway

Then copy ~/git/openwrt-mqtt-sn-gateway/feeds.conf into your openwrt/sdk directory.

Compile

go into your openwrt/sdk directory and update and install the feed by executing: (Like in this tutorial step: https://openwrt.org/docs/guide-developer/helloworld/chapter4)

./scripts/feeds update mqttsngateway
./scripts/feeds install -a -p mqttsngateway

Then configurate the environment (like in this tutorial step: https://openwrt.org/docs/guide-developer/helloworld/chapter5): Run make menuconfig, and select the MQTT-SN sub-menu. Highlight the mqttsngateway entry underneath this menu, and click on the Y key to include this package into the firmware configuration. Exit the menu, saving your changes. You can then build the package by issuing the following command:

make package/udpmqttsngateway/compile

If everything went successfully, we are presented with a brand new package named mqttsngateway1.0-1_<arch>.ipk in bin/packages/<arch>/mypackages folder. Then upload the ikp.file to your your device and install:

root@OpenWrt:/# opkg install mqttsngateway1.0-1_<arch>.ipk

MQTT-SN Gateway Configuration

Next add a MQTT.CON and a MQTTSN.CON file into your home-directory. Example MQTT.CON file:

brokeraddress 192.168.178.33
brokerport 1883
clientid mqtt-sn linux gateway
willtopic /mqtt/sn/gateway
willmessage /mqtt-sn linux gateway offline
willqos 1
willretain 0
gatewayid 2

Example MQTTSN.CON file:

gatewayid 2
timeout 10
advertise 900

And start the mqtt-sn-gateway:

root@OpenWrt:/# mqttsngateway

If everything worked correctly you should see:

root@OpenWrt:/# mqttsngateway
