iotivity-node Examples

COAPS

The files high-level-client.coaps.js and high-level-server.coaps.js are for a client/server pair illustrating DTLS access to a resource. To run the example, please follow the steps below:

0. In addition to iotivity-node, build iotivity with SECURED=1 and RD_MODE=all. Let the root of the iotivity repository be $iotivityRoot.

1. Calculate the sha256 sum of the server. The example below assumes the server is located in /home/user/iotivity-node/js/high-level-server.coaps.js. Replace the path in the example below with the actual absolute path to the file high-level-server.coaps.js.

   echo -n '/home/user/iotivity-node/js/high-level-server.coaps.js' | sha256sum

   Copy the resulting value to the clipboard. Let the value be $serverHash.

2. Create the directory ${HOME}/.iotivity-node/$serverHash.

   mkdir -p ~/.iotivity-node/$serverHash

3. Copy the file $iotivityRoot/resource/csdk/security/provisioning/sample/oic_svr_db_server_justworks.dat to ${HOME}/.iotivity-node/$serverHash/oic_svr_db.dat

4. Start the server

   node high-level-server.coaps.js

5. Switch to the directory where iotivity built the provisioning client, and run it from there. Let $platform be the platform for which you build iotivity, $architecture be the architecture for which you built iotivity, and $buildType be the build type - i.e., release for a production build, and debug for a development build.

   cd $iotivityRoot/out/$platform/$architecture/$buildType/resource/csdk/security/provisioning/sample
   ./provisioningclient

6. Choose 11 from the menu by typing 11 and pressing Enter to discover unowned devices. The server should be listed under "Discovered Unowned Devices" with uuid 12345678-1234-1234-1234-123456789012.

7. Choose 20 from the menu by typing 20 and pressing Enter to assume ownership of the devices discovered in the previous step.

8. Choose 99 to exit the client.

9. Calculate the sha256 sum of the client. The example below assumes the client is located in /home/user/iotivity-node/js/high-level-client.coaps.js. Replace the path in the example below with the actual absolute path to the file high-level-client.coaps.js.

   echo -n '/home/user/iotivity-node/js/high-level-client.coaps.js' | sha256sum

   Copy the resulting value to the clipboard. Let the value be $clientHash.

10. Create the directory ${HOME}/.iotivity-node/$clientHash.

    mkdir -p ~/.iotivity-node/$clientHash

11. Copy the file oic_svr_db_client.dat from the current directory (in which the provisioningclient program was built) to the newly created directory and rename it to oic_svr_db.dat.

    cp ./oic_svr_db_client.dat ${HOME}/.iotivity-node/$clientHash/oic_svr_db.dat

12. Launch the client.

    node high-level-client.coaps.js
