• scala prototype version
• thread sync
  • hid4java used separate thread for usb events. Sync with main agent thread needed.
  • access to usb device in wrong thread cause jvm crash in native code call (on os x)

Problems with libusb:

• unable to claim device because of dump kernel driver in OS X for unknown usb devices

• implementation
• unittests
• logging - blocked by #13

• root build.sbt
• multiproject build
• upgrade deps
• extract the influxdb client
  • add unittest for data.* class method
• release

• update deps to jre8+

blocks #29

• warning+ by default
• verbose option
• logback config path option
• via log4s

• separate option
• generalize analysist

Something like that:

java -jar ambient7-mt8057-agent-x.x.x.jar --writers=mqtt --host=localhost --topic 'sensors/co2' 

Thank you.
