Hi,

does Azure IoT hub accept MQTT 3.1?  The latest is 3.1.1.

- data.MQTTVersion = 3 selects MQTT 3.1

- data.MQTTVersion = 4 selects MQTT 3.1.1

This may seem odd, but it's the way that it is defined in the protocol.  The good news is that in the next revision of the protocol, both numbers become 5 :-)

Hi,

I use paho mqtt embedded for publish message for azure iot hub.

I compile source with visual studio 2008 ,ARM G45 architecture.

I use the following configuration :

Main file : qos0pub.c

 

char *host = "TestAcoemIotHub.azure-devices.net";

//int port = 1883;

int port = 5671;

data.clientID.cstring = "DeviceAcoem";

data.keepAliveInterval = 20;

data.cleansession = 1;

data.username.cstring = "TestAcoemIotHub.azure-devices.net/DeviceAcoem";

  data.password.cstring = "SharedAccessSignature sr=TestAcoemIotHub.azure-devices.net%2fdevices%2fDeviceAcoem&sig=XXXXXXXEgyP2%2bH0H1WKx2rJBOZAEDqMA4uHT5AFJ8%3d&se=1498744862";

data.MQTTVersion = 3;

topicString.cstring = "DeviceAcoem";

 

I have a successfully published message but no iot message received in the azure dashboard.

 

Thanks for your reply
