azure-iot-hub vs azure-iot-sdk and identity.

[alemag1986]

Hi team,

First question, since we rely on IotHub for our daily ops and we are building services and processes around it, we would like to know if this library azure-iot-hub is the way to go or it has been deprecated, since it looks stale and we should favor azure-iot-sdk?

Second to that, we are trying to get rid of all connection string as much as possible. Our middleware, runs on Azure and the webapp has all the needed permissions to operate the IoTHub, create new devices, change device twin definition, check the state of devices and send direct methods. With that in mind, we haven't been able to integrate azure-identity. Does the library support Identity using something like DefaultAzureCredential from the azure-identity package? If identity is a possibility, do you mind sharing an example?

Kind regards,
Alejandro

They are two different libraries for different purposes.

azure-iot-hub-python is the service API to connect for example your API in Python to Azure to send cloud to device messages.

azure-iot-sdk-python is the device API to connect your device running Python to for example read messages sent from the cloud.
https://learn.microsoft.com/en-us/azure/iot/iot-sdks#device-sdks

Second question, yes you can use from azure.identity import DefaultAzureCredential, I have not tested it yet but has a sample for it.

Sample:

1. Create credential
   

   azure-iot-hub-python/samples/iothub_registry_manager_token_credential_sample.py

   Lines 48 to 50 in 8c8f315

   	# https://pypi.org/project/azure-identity/ for more information on
   	# authenticating with DefaultAzureCredential or other implementations of TokenCredential.
   	credential = DefaultAzureCredential()

2. Use from_token_credential
   

   azure-iot-hub-python/samples/iothub_registry_manager_token_credential_sample.py

   Lines 61 to 62 in 8c8f315

   	# Create IoTHubRegistryManager
   	iothub_registry_manager = IoTHubRegistryManager.from_token_credential(url, credential)
