This repo contains bash scripts to setup a build enviroment to use DeviceBuilder with IoTivity Classic. The scripts setup the next repos (from git) in the folders:
- IoTivity Classic (IOTivity 1.3.1 or 2.0.0)
- DeviceBuilder (latest version)
- mraa (MRAA library to interact with HW)
All repos are being set up 1 level above the folder of IOTivity-setup folder.
Running the curl command below installs the development environment with IOTivity 1.3.1:
curl https://openconnectivity.github.io/IOTivity-setup/install.sh | bash
Running the curl command below installs the development environment with IOTivity 2.0.0:
curl https://openconnectivity.github.io/IOTivity-setup/install2.0.sh | bash
for manual installation instructions see: https://github.com/openconnectivity/IOTivity-setup/blob/master/advanced.md

The installDeviceBuilder script generates scripts in the folder above this repo. These scripts are convienent scripts, e.g. they are short cuts for entering generation, build, excute and reset commands.

Note: if gen.sh is run again, the generated code is overwritten.
e.g. before running that tool again, safe the file in the iotivivty tree to another name
if one wants to keep that code as reference

This scripts edits the device builder input file with nano.
Nano is supplied on various linux systems like ubuntu and pi. The file being edited is the file in IoTivity classic tree. so please make sure when generating a new version, that a changed file is saved under a different name.

Device Builder input file information can be found at: https://github.com/openconnectivityfoundation/DeviceBuilder/tree/master/DeviceBuilderInputFormat-file-examples
This script runs the DeviceBuilder with the arguments:
- ~IOT/example.json as input file
- light device as device type
when the device type needs to change from oic.d.light to something else the next mechanisms are available to change the device type:
- change the server code from oic.d.light to the specific value
- search for oic.d.light in the server code, and change the value.
- no need to re-generate the server code
- can be done when one is already changing the server code.
- change the gen.sh file e.g. replace oic.d.light to something
- to see the changes the code needs to be re-generated by running gen.sh
- can be done when no code has been changed yet.
Running this script generates the device_output folder AND copies the result to the correct executable folder in the IoTivity classic tree structure.
copied to the executable folder from the device:
- server.cpp to simpleserver.cpp in the examples/OCFDeviceBuilder folder
- introspection file (in CBOR format) to the out/linux/$ARCH/release/examples/OCFDeviceBuilder directory
- security file (in CBOR format) to the out/linux/$ARCH/release/examples/OCFDeviceBuilder directory
- The original JSON file is using "just works" onboarding
This scripts edits the code with nano. The file being edited is the file in IoTivity classic tree. so please make sure when generating a new version, that a changed file is saved under a different name.
This script builds the examples/OCFDeviceBuilder by means of scons.
e.g. run in the IoTivity classic folder the scons examples/OCFDeviceBuilder command
This script executes the executable in the folder where the executable resides in.
linux executes in folder:
./iotivity/out/linux/x86_64/release/examples/OCFDeviceBuilder
pi executes in folder:
./iotivity/out/linux/armv7l/release/examples/OCFDeviceBuilder
note that the executable needs to be started in folder where it recides to avoid issues with reading the security and introspection files.
This script overwrites the SVR settings in the security file from the device_output folder to the out/linux/$ARCH/release/examples/OCFDeviceBuilder folder.
Note execute this command only when the device is not running. The device will go to the ready for onboarding state.
