- A Java application reads the Frames coming from the Wireless Interfaces
(ZigBee, WiFi, 3G, 868/900MHz, etc) and parse them. Then they are
inserted in a MySQL DB:
CREATE TABLE IF NOT EXISTS `sensorParser` (
`id` int(11) NOT NULL auto_increment,
`id_wasp` text character set utf8 collate utf8_unicode_ci,
`id_secret` text character set utf8 collate utf8_unicode_ci,
`frame_type` int(11) default NULL,
`frame_number` int(11) default NULL,
`sensor` text character set utf8 collate utf8_unicode_ci,
`value` text character set utf8 collate utf8_unicode_ci,
`timestamp` timestamp NOT NULL default CURRENT_TIMESTAMP,
...
PRIMARY KEY (`id`)
)

1º – Get a namespace + credentials (ACS authentication)
2º – Needed to start the program
public static void AzureSetup(){
config = ServiceBusConfiguration.configureWithWrapAuthentication(
AZURE_NAMESPACE,
AZURE_OWNER,
AZURE_KEY,
".servicebus.windows.net",
"-sb.accesscontrol.windows.net/WRAPv0.9");
service = ServiceBusService.create(config);
}

3º – Get from Azure service the queues already created in the
namespace. We store this queues in order to avoid creating an already
existent queue.
public static void AzureGetQueues(){
try {
queue_list_result = service.listQueues();
queue_list = queue_list_result.getItems();
...
}
…
}

4º – Then we read from our internal Data Base (MySQL) the sensor data
bufferized. e.g: 100 registers
SELECT id,id_wasp,id_secret,sensor,value,timestamp,sync FROM LOCAL_TABLE WHERE
sync^SYNC_MASK ORDER BY timestamp DESC LIMIT 100;

5º – Then we create the JSON files with the next format
{
"id_wasp": "SmartWater",
"id_secret": "366360762",
"sensor": "ORP",
"value": "0.380",
"datetime": "02/12/2014T12:18:57+0000"
}

6º – Just send each file to the opened queue
public static int AzureSendToQueue(String queuename, String data) {
try{
appendToLogFile("Sending message to queue: "+queuename, 1, 2);
appendToLogFile("Data: "+ data, 1, 2);
message = new BrokeredMessage(data);
message.setProperty("Queue", queuename);
service.sendQueueMessage(queuename, message);
...
}
catch (ServiceException e){
...
}
}
