9 Azure IoT Hub is designed around standalone end devices communicating directly with the hub. Each end device must connect to the hub via one of the supported communication protocols ([[MQTT>>url:https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-mqtt-support]] / [[AMQP>>url:https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-amqp-support]]). These protocols are inherently stateful - each individual end device must have one connection always open in order to send and receive messages from the Azure IoT Hub.
10
11 The Azure IoT Hub integration prefers to use an asynchronous, stateless communication style. When uplink messages are received from an end device, the integration connects on demand to the Azure IoT Hub and submits the message, and also updates the Device Twin. The data plane protocol used between The Things Stack and Azure IoT Hub is [[MQTT>>url:https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-mqtt-support]], and the connections are always secure using [[TLS 1.2>>url:https://datatracker.ietf.org/doc/html/rfc5246]].

32 == 2.2 Create API Key ==
33
34
35 Go to your application in The Things Stack Console, navigate to (% style="color:blue" %)**Integrations → Azure IoT**(%%) on the left hand menu and click on (% style="color:blue" %)**Expand** (%%)next to (% style="color:blue" %)**Azure IoT Hub**(%%). Now click on (% style="color:blue" %)**Generate API Key**.
36
37
38 [[image:image-20230105112836-1.png]]
39
40
41 Copy the generated API key and store it in a safe place, because you will need it in the next section.
42
43 Leave the integration page open, as you will need to copy in your (% style="color:blue" %)**Azure IoT Hub hostname** (%%)and (% style="color:blue" %)**Azure IoT Hub access key**(%%) before saving the integration.

96 = 3. Managing Devices =
97
98
99 The Azure IoT Hub integration for The Things Stack synchronizes the device registry: you can create devices in Azure IoT Hub which trigger an Azure Function that creates the device in The Things Stack.
100
101
102 (% style="color:red" %)**Note:**
103
104 Devices that you create in The Things Stack are automatically created as Azure IoT Hub devices as soon as they activate or send their first uplink message.
105
106 In Azure IoT Hub, create only devices that are not yet in your The Things Stack application.
107
108
109 (% style="color:blue" %)**Device Names:**
110
111 Devices are created automatically as they join the network or send an uplink message. For the name of new devices, the end device ID in The Things Stack is used as the device ID in Azure IoT Hub.
112
113
114 == 3.1 Creating Devices ==
115
116
117 You can use Azure IoT Hub to create and claim devices in The Things Stack. This is useful to manage all your devices in one place, without having to use The Things Stack Console, CLI or API.
118
119 (% style="color:blue" %)**Creating**(%%) a device allows you to add any LoRaWAN device by manually entering its information and security keys.
120
121 In the Azure Console, open your Azure IoT Hub resource. In the menu on the left, click (% style="color:blue" %)**IoT Devices**.
122
123 Click (% style="color:blue" %)**Add Device**.
124
125 [[image:image-20230105112836-6.png]]
126
127
128 As (% style="color:blue" %)**Device ID**(%%), enter any device ID you like. Hit (% style="color:blue" %)**Save**.
129
130
131 (% style="color:red" %)**Note:**
132
133 See [[ID and EUI constraints>>url:https://www.thethingsindustries.com/docs/reference/id-eui-constraints/]] for guidelines about choosing a unique ID.
134
135 [[image:image-20230105112836-7.png]]
136
137
138 You will now have to setup the LoRaWAN specific settings of the device. Click on (% style="color:blue" %)**Device Twin**.
139
140 [[image:image-20230105134348-1.png]]
141
142
143 You will now be presented with a JSON document containing the Device Twin. You now have to add a new object called tags, which will contain an object called lorawan with the LoRaWAN specific tags. You will have to specify the following tags:
144
145 * (% style="color:#037691" %)**devEui:**(%%) the hexadecimal LoRaWAN DevEUI.
146
147 * (% style="color:#037691" %)**joinEui:**(%%)** **the hexadecimal LoRaWAN JoinEUI (or AppEUI).
148
149 * (% style="color:#037691" %)**lorawanVersion:**(%%) either 1.0, 1.0.1, 1.0.2, 1.0.3 or 1.1.
150
151 * (% style="color:#037691" %)**regionalParametersVersion:**(%%) either 1.0, 1.0.1, 1.0.2 (or 1.0.2-a), 1.0.2-b, 1.0.3-a, 1.1-a or 1.1-b.
152
153 * (% style="color:#037691" %)**appKey:**(%%) the hexadecimal LoRaWAN AppKey.
154
155 * (% style="color:#037691" %)**nwkKey:**(%%) the hexadecimal LoRaWAN NwkKey (only when using LoRaWAN 1.1 or higher).
156
157 * (% style="color:#037691" %)**frequencyPlanId:**(%%) the frequency plan ID. See [[Frequency Plans>>url:https://www.thethingsindustries.com/docs/reference/frequency-plans/]] for the supported values.
158
159 If your end device is a part of the [[LoRaWAN Device Repository>>url:https://www.thethingsindustries.com/docs/integrations/payload-formatters/device-repo/]], you may provide the identifiers of the device as part of an optional versionIdentifiers object. You can specify the following information as part of the identifiers:
160
161 * (% style="color:#037691" %)**bandId:**(%%) the band ID.
162
163 * (% style="color:#037691" %)**brandId:**(%%) the brand ID.
164
165 * (% style="color:#037691" %)**firmwareVersion:**(%%) the firmware version.
166
167 * (% style="color:#037691" %)**hardwareVersion:**(%%) the hardware version.
168
169 * (% style="color:#037691" %)**modelId:**(%%) the model ID.
170
171 (% style="color:red" %)**Note:**
172
173 If the version identifiers are provided, the end device will automatically load the [[Payload Formatters>>url:https://www.thethingsindustries.com/docs/integrations/payload-formatters/]] from [[LoRaWAN Device Repository>>url:https://www.thethingsindustries.com/docs/integrations/payload-formatters/device-repo/]].
174
175 The final JSON tags object should look as follows:
176
177 {
178
179 "lorawan":{
180
181 "devEui":"0004A30B001C5838",

213
214 Click on (% style="color:blue" %)**Save**(%%) in the top-left corner. The end device will now be created in The Things Stack.
215

217 == 3.2 Deleting Devices ==
218
219
220 In the Azure Console, open your Azure IoT Hub resource. In the menu on the left, click (% style="color:blue" %)**IoT Devices**.
221
222 Click on the checkbox in front of the device you want to delete, then click (% style="color:blue" %)**Delete**.
223
224 [[image:image-20230105112836-10.png]]
225
226 The end device will be deleted from Azure IoT Hub and The Things Stack.
