Hai,

I'm using MQTTBox for testing the device to cloud connection. I have registered on Azure. I try to establish a connection to the cloud using MQTTBox. But Connection error is shown on there.

Host =iothubhostname

username={iothubhostname}/RIOD_GREECE_TEST1/api-version=2016-11-14

client id=RIOD_GREECE_TEST1

password =SAS token generated using "visual studio code"(using shared access policies)

it has been saying connection error

is the parameters are correct?

is there is any other method for generating a password? with example?

    Hello @Akhil joy , Thanks for reaching out to us!

    Here is my MQTTbox connection how I am connecting to IoTHub and sending messages..

    Please verify your IoT Hub Host name and use only one MQTTbox connection at a time.

    The right host should be the fully qualified name: sabiothub.azure-devices.net

    • MQTT Connection Name - This is any name that you want to give the connection, only visible in MQTTBox.
    • MQTT Client ID - This is the Azure IoT Device name from above.
    • Host - This is the Azure IoT Hub URI, and we will need to modify this a little bit. The entire connection string should look like:
    {IoT Hub Name}.azure-devices.net/$iothub/websocket
    Or
    {IoT Hub Name}.azure-devices.net
    • Username - is the FQDN name of the IoT Device, with some additional information. It should look like the following:
    {IoT Hub Name}.azure-devices.net/{Device Name}/?api-version=2018-06-30
    • Password - is the SAS token that was generated from above.
    Example: SharedAccessSignature sr=sabiothub.azure-devices.net%2Fdevices%2Freadyiotedgevm&sig=%Fo4Gty07ww%3D&se=1598
    • Append timestamp to MQTT client id -This should be set to "No".
    • SSL/TLS Version - This should be set to Auto.
    • Will - QoS - This should be set to 1
    • SSL/TSL Certificate Type - This should be set to CA signed server certificate.

    I have included the image which gives all details on MQTTBox.
