Publish With Python To Azure Iot Hub - Subscribe With C# Not Working

I publish with M2MQTT Paho Python library on the device as follows: msg = 'POS {} {} {} {} {} {} {}' msgtosend=msg.format(tagNum, tagID, x_pos, y_pos, z_pos, qos, unk)

Solution 1:

try the following fix:

tpc = new string[] { 
    "devices/MasterTag/messages/devicebound/#",
    "$iothub/twin/PATCH/properties/desired/#",
    "$iothub/methods/POST/#", 
    "$iothub/twin/res/#"
    };

qosArray = new byte[] { 
    MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE, 
    MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE, 
    MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE,
    MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE
   };

var subCode = mqttClient.Subscribe(tpc, qosArray);
