from IoTcloud.AWS import AWS
aws = AWS(things_name='', host='', port=0, keepalive=0, cert_file_path='', private_key_path='')- Initialize client:
- Click the Add button in the initialization block to import Device certificate + Private Key File, Note: The default key and certificate file name is too long, try to change it to a shorter string.
- The things name is the name of the device we created, and it needs to match the name in the AWS Management Console.
- Copy the Endpoint field from AWS Management Console->Settings and populate it with the HOST parameter.
- For the port parameter we use the MQTT service port 8883
- keepalive 60
- For more information on service ports please refer to AWS Official Documentation.
aws.start()- Start client connect
aws.publish(topic,msg)- publish messages
def fun_subtopic_(topic_data):
