What adapters do?

In order to understand, what we can generalize, we need to know, what adpters do, and find common implementations (*) in adapters.

What adapters do? (publishers)

– create XMPP connection (*)

– read config settings (*)

– parse XML (specific for each type of sensor) (*)

– opens connection to device

– starts XMPP connection (*)

– starts an cycle

– get data from device

– prepares sox message (with device installation and transducers installation info as well sensor data values) (*)

– publish sox message (*)

Files: config.xml and device_kind.xml

config.xml(*) > information for connection and identification  (host, port, username, password, device id, …)

device_kind.xml > device specific informations (eg: serial port location, database, … )

– also compiled sox libs and tools on mac os x server

—> installed macports as normal user ( info )

—> installed glib2 from macports (perl installation issue with owner > solution)

—> installed loudmouth lib

—> installed sox lib (osx shared lib compilation issues > solution)

—> installed cmd_line_tools (needs -lgcrypt -lglib-2.0  in Makefile)

– installed an bash script to publish minime server cpu temp  every 10 minutes.

sensor name: minime_cpu_sensor
sensor id: 001
event node: minime_cpu_temperature
publisher: salvador@openfire
host: hci.dme.uma.pt
port: 10223

Now we can subscribe to cpu temperature sensor data, as well  get last data from node. (by default is FIREFLY sensor packet)
