Hi Guys

Has anyone tried to connect to Azure IoT Hub?

I tried to connect to a IoT Hub directly with the MQTT driver. But I always get
As describet in de Microsoft Doc's I used the following. For the Password I used a SAS token, generated with Visual Studio Code.

• Port: 8883

• Username: {iothubhostname}/{device_id}/?api-version=2018-06-30

• Password: SharedAccessSignature sig={signature-string}&se={expiry}&sr={URL-encoded-resourceURI}

Since you have to use a secured connection to the IoT Hub, I used TLS. And therefore I entred in the certificate field the DigiCert Baltimore Root Certificate.

Firewall, Ports ect. are open.

Anyone an idea what could be wrong?

best regards
Aleks
