ubisys® Smart Facility™ Adapter for IoTivity

This project has been sponsored jointly by ubisys technologies GmbH and Qorvo, Inc. and is licensed under the Apache License, Version 2.0; You may obtain a copy of the license at http://www.apache.org/licenses/LICENSE-2.0.

Overview

Project "Morpheus" provides a piece of software that acts as an adapter between the ubisys Smart Facility Service and the Open Connectivity Foundation's IoTivity project, connecting the world's first certified ZigBee 3.0 gateway platform to IoTivity. As a result, it does not only bridge conventional ZigBee products like relays, dimmers, smart plugs, and light bulbs to OIC, but it does also fully support energy-harvesting ZigBee Green Power devices - another world's first.

Intended Usage

The Smart Facility Adapter for IoTivity is compatible with all gateways and home hubs running the ubisys Smart Facility Service, including the ubisys ZigBee Gateway G1, the Qorvo ZigBee 3.0 Gateway reference design based on the GP712, and custom hardware platforms incorporating the ubisys core ZigBee gateway services.

Typically, the adapter would run on the gateway platform itself and connect to the local Smart Facility instance, but it can also connect to a remote facility service over an IPv4 or IPv6 connection.

Supported Device Types

Following mappings between ZigBee features and OIC models are supported:

OIC Binary Switch ("oic.r.switch.binary") <-> ZigBee On/Off Cluster (0x0006)
OIC Water Sensor ("oic.r.sensor.water") <-> ZigBee IAS Zone Cluster (0x0500), "Water Sensor" (ZoneType 0x002A)
OIC Contact Sensor ("oic.r.sensor.contact") <-> ZigBee IAS Zone Cluster (0x0500), "Contact Switch" (ZoneType 0x0015)
OIC Motion Sensor ("oic.r.sensor.motion") <-> ZigBee IAS Zone Cluster (0x0500), "Motion Sensor" (ZoneType 0x000D)
OIC Fire Sensor ("oic.r.sensor.fire") <-> ZigBee IAS Zone Cluster (0x0500), "Fire Sensor" (Zone Type 0x0028)

Implementation details, build instructions and requirements

The project hosted at https://github.com/ubisys/iotivity is a fork of the official IoTivity 1.2 release, available at https://github.com/iotivity/iotivity. The changes made by ubisys affect IotivityandZigBeeServer, such that it utilizes the new ubisys ZigBee 3.0 plug-in for IoTivity, which is a drop-in replacement for zigbee_wrapper. For testing, you could use IotivityandZigBeeClient, which remained unmodified.

Notice that unit tests for the ubisys ZigBee plugin are currently not supported and attempting to build them would fail. It is recommended to just build the server and client, as described below.

This project heavily relies on the ubisys Smart Facility Service C++ Client SDK, which is a closed-source library. A C++ 11 compiler is required, e.g. GCC 4.9.3 or above.

Building

1. Make sure open-source libraries are installed

Following open-source libraries are required and should be installed on your build system: libuuid, libbsd, libev They can typically be installed using your distribution's package manager, for example on an ubuntu 14.04.5 LTS, use the following commands:

sudo apt-get install libuuid1 libbsd0 libev4

2. Copy dependencies

Make sure to add libev++ and libfacility for your target platform to the /extlibs/ubisys folder, under the respective subfolders, i.e. /include for the headers and /local for building on the local host (currently no cross-builds supported). You might also have to add additional external dependencies, as required by vanilla IoTivity. Then you will be prompted to install specific packages, e.g.

git clone https://github.com/01org/tinycbor.git extlibs/tinycbor/tinycbor -b v0.4

3. Build the debug version of client and server

Make sure the current working directory is the iotivity top-level directory. Then run scons. Notice the target string depends on your specific architecture (x86_64 in this case) and build configuration (debug build in this case):

scons out/linux/x86_64/debug/plugins/samples/linux/iotivityandzigbeeserver RELEASE=false
scons out/linux/x86_64/debug/plugins/samples/linux/iotivityandzigbeeclient RELEASE=false

4. Build the release version of client and server

scons out/linux/x86_64/release/plugins/samples/linux/iotivityandzigbeeserver
scons out/linux/x86_64/release/plugins/samples/linux/iotivityandzigbeeclient

Addtional hints for targetting the ARM architecture

Make sure to specify TARGET_ARCH=arm and to use arm instead of x86_64 in the target path, i.e.

scons out/linux/arm/debug/plugins/samples/linux/iotivityandzigbeeserver TARGET_ARCH=arm RELEASE=false

Trouble-shooting

If you have problems buidling, first try to build vanilla IoTivity on your build system. Once that works, follow the instructions above to build the ubisys ZigBee plug-in.

Commissioning instructions

Currently, the PIN code is hard-coded as "0000", so you need to allow enrollment on the Facility Service (for ubisys G1 use the web interface, as a platform vendor use the facility-manage command line tool or your own user interface) with this PIN code, then connect. After initial enrollment, the credentials are stored permanently.

Start the IotivityandZigbeeServer application (plugins/samples/linux) and provide hostname[:port] for the facility service instance on the command line.
