really great app but the underlying protocol is the real genius
behind the app.
Was able to develop a relatively sophisticated interface for an arduino project in a short time with straight forward code.
Just about any embedded micro project can benefit from the interface that this app provides.”

Unleash the power of your Arduino or other micro project with pfodApp. Show people that you are not just playing with circuits but building useful devices, like a garage door remotes, dimmable room lighting, etc, that they can control from their Android mobile. This single pfodApp can control multiple devices each with different functions. pfodApp V3 add support for creating your own sophisticated controls, No android programming required.
Using pfodApp on an Andriod mobile, your users can read text prompts in their own language, send navigation commands, traverse menu hierarchies, choose from single and multi-selection lists, input numbers and text and plot and view data sent by your micro. You can send sensor readings to your mobile and have them plotted and saved in a file for later downloading to your computer.
The pfodApp does all of the Android stuff for you and remembers the menu hierarchy. You only need to code your micro to be a pfodDevice which responds to simple requests over Bluetooth, BLE or Wifi/Internet or SMS and sends back simple micro-pages in response. The controls, text and user choices displayed on the Android mobile by the pfodApp are completely determined by what you code in your micro. No Android coding is required. The pfodApp handles it all.
Wifi/Ethernet and SMS connections offer optional 128 bit security to guard against hackers connecting to or taking control of your device. See Challenge and Response Security for Internet connected pfodDevices for the details. An Arduino library, pfodSecurity, part of the pfod libraries, implements this 128 bit security on the pfodDevice. See A Simple WiFi/Arduino pfodDevice for example code and how to generate and load the 128 bit password. For details of SMS connection see this page.

See below for how to turn your micro processor project into a pfodDevice that can be controlled by this pfodApp. You can also just connect to your PC via bluetooth or wifi to test out how your micro-pages will be displayed on the pfodApp and what message will be returned when the users makes selections. See Serial Bluetooth Connections from your Mobile Phone to you PC for details on making bluetooth connections from you mobile to Window, Mac and Linux.
