Demo

Run three devices to show how jobs can be used to run a firmware upgrade on a subset of devices and report status through Device Twins. Assumes you have already created a Azure IoT Hub.

Pre-requisites

1. install npm i -g iothub-explorer
2. Azure Cli 2.0

If on Windows use Bash for Windows or Git Bash to run the commands.

1. Create devices

1. . ./utils/login.sh <iothubowner-constring>
2. . ./utils/create-policy.sh <iothubname>
3. . ./utils/create-device.sh ds1
4. . ./utils/create-device.sh ds2
5. . ./utils/create-device.sh ds3

2. Assign tags to devices

1. node service\tag-device.js <connstring for jobs permissions> ds1 US
2. node service\tag-device.js <connstring for jobs permissions> ds1 US
3. node service\tag-device.js <connstring for jobs permissions> ds1 Canada

3. Start Devices

1. node app\device.js <connstring ds1> nt
2. node app\device.js <connstring ds2> nt
3. node app\device.js <connstring ds3> nt

4. Schedule a job

1. node service\job-schedule.js <connstring for jobs permissions> US

5. Check the job status

1. node service\job-status.js <connstring for jobs permissions> or node service\get-job.js <connstring for jobs permissions> <jobid>
