[sgmb id=”1″]Currently I’am working on a project, where device management (dm) is needed. So a part of dm is to control devices remotely. My setup is a linux based device, that is connected to Azure Clouds IoT Hub with the new DeviceManagement-Feature. That device is controled by a NodeJs-App. One task of that is, to handle a reboot signal from the cloud. The problem I had, was to break through the node.js environment and to convince the device, to reboot. After some try-outs, I came up with following simple solution – maybe someone has the same problem, than this is a good start:

1) npm install sys child_process

2) …and use it as follows:

var sys = require('sys')
var exec = require('child_process').exec;
function puts(error, stdout, stderr) {
  sys.puts(stdout)
};
exec("reboot");

cheers!
