How to connect to SSH over usb connection from PC

the usb is either usb_storage or usb_net

How is The Other Half connecting to the Phone?

  • NFC (a unique ID)
  • I²C (bandwidth/pins unknown as of yet)
    • 1,8V I2C (400kHz default setting in kernel)
    • Other half expected to work in slave mode, phone is master
    • Dedicated INT GPIO (1,8V) for interrupts
  • power in (for charging)
  • power out (for using battery)
    • 3,3V VDD (max 300mA, preferrably < 150mA to avoid thermal issues)

and of course also

  • Bluetooth
  • Wifi
  • USB

Where do I put .apk files

  1. download from web and choose install

or

  1. put apk into ~/ (home directory)
  2. launch it with "xdg-open `pwd`/${app}.apk" (where $app is your app name)
