Microsoft Azure IoT中心和不带DeviceId的connectionString

Question

I've got a connectionString from a third party to Microsoft Azure IoT Hub which doesn't contain a DeviceId .

I've tried to use this SDK, but it requires a DeviceId : https://www.npmjs.com/package/azure-iot-device-http

Can one use Azure IoT Hub without DeviceId ?

Answer 1

Yes it should work as a IOT hub. Basically from the connection string which we get it from Azure portal doesn't include device id.

Sample for initializing a client and creation of device.

var iothub = require('azure-iothub');

var connectionString = '[IoT Connection String]';

var registry = iothub.Registry.fromConnectionString(connectionString);

// Create a new device
var device = {
deviceId: 'sample-device-' + Date.now()
};

registry.create(device, function(err, deviceInfo, res) {
    if (err) console.log(op + ' error: ' + err.toString());
    if (res) console.log(op + ' status: ' + res.statusCode + ' ' + res.statusMessage);
    if (deviceInfo) console.log(op + ' device info: ' + JSON.stringify(deviceInfo));
});
