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)
