Hi I'm providing the connection string for device but still i'm getting an error as "Device ID is required" and FYR my connection string is as follows "HostName=Hostname.azure-devices.net;DeviceId=simDevice;SharedAccessKey=accesskey"

@vasanthkukumar can you share code or command you're trying to run?

my mistake was that I was not setting IOTHUB_DEVICE_CONNECTION_STRING environment variable.. the code uses os.Getenv
