What is USB-OTG?

OTG is an abbreviation for “On-The-Go”. It is a specification that allows devices such as smartphones to act as a host, allowing other USB peripheral devices like a USB disk-on-key, mouse, keyboard  or camera to be attached to them (this is why OTG capability is sometimes referred to as “host mode”).

Unlike conventional USB connectivity, in USB-OTG connections the host (in our case the Smartphone) will provide 5V power feed to the peripheral device (in our case the Therm-App™ device). It will also control and read the raw data from it.

The USB-OTG standard makes use of a special wiring trick inside the USB connector in order to signal the Smartphone that it should become a host. This is why Therm-App only works with  USB-OTG cables. For more info see: http://en.wikipedia.org/wiki/USB_On-The-Go or http://www.usb.org/developers/onthego/

  3. Connect the USB-OTG cable to both Therm-App™ and your mobile device.
  4. Your Android operating system will ask for your permission to associate the USB device with the Therm-App™ application. Approve and continue.
  5. The Therm-App™ application will automatically start.

What if my Therm-App™ device isn’t working?

If this is your first time operating the device, you might want to check our installation guidelines.

If you have already used the Therm-App™ device, please try the following:

  • Disconnect both sides of the cable, then reconnect it .
  • Restart your phone, then try launching Therm-App™ again.
