• 20151206 after reset Spark/Particle core lost connectivity again, just breathing green.
  • Set to yellow download mode, then
  • $ sudo particle flash --usb deep_update_2014_06
  • Flashing magenta. From Particle android app, reflash Tinker, works after a while.

  • from https://build.particle.io re-flash program

• bought a couple spark core's through a kickstarter project, name changed to particle.io

  • been a bit disappointed, confusing documentation, lack of instructions, units stuck not connecting etc.
• 201512 got firmware flashed onto cores, the connect to internet and particle.io android ap can switch a led on and off, going to try one wire temperature monitoring again.

• 201512 - four core cable to 3pin ds1020,

  • 

  • pin1-GND(Yellow), pin3-vcc(Red), pin2-data(Green) with pull-up 4.7k resistor.
• Go

  1. login into web builder https://build.particle.io , i can see my devices.

  2. start new project TempMon

     1. add libraries
        • ONEWIRE
        • SPARK-DALLAS-TEMPERATURE
