WOD (Watch On-board Diag)

Small OBDII app for Android Wear based watches for real time parameters displaying.
This app is relatively old, the author suggest to use the Pulta OBDII watchface instead.
Please consider using this app "as is", mainly for demo purposes and for testing the link between your watch and you car via OBDII Bluetooth adapter.
The app connects your smartwatch to your car ECU via Bluetooth directly, without needs of any smartphone.
Using the Android smartwatches possibilities, it displays the car real-time data.
Was tested on Asus Zenwatch and cheap ELM327 mini Bluetooth adapters. The name must begin with "OBD" no matter they're capital letters or not.
Displays the On-Board Voltage, Engine Coolant temperature,
Calculated Engine load, RPM, Boost, Vehicle speed.
WARNING: Please don't drive a car while playing with this app!
First, please prepare your OBDII Bluetooth adapter, put it into the car (if you're experienced enough you can just connect some power supply or even battery 6...12 V to its " " and "-" pins).
Perform device searching/pairing in your WATCH settings, after finding, type pincode (usually "1234" or "0000").
Then launch the WOD app. It must connect the adapter automatically or by pressing the "Start" button. Next, the screen with the Voltage gauge will be displayed. To switch screens, please tap right part of the touch screen to increase the screen number and left one to decrease. The "Connected" message means that the watch was connected to OBDII Bluetooth adapter. On-board voltage is accessible just after the adapter is powered. Other parameters need the ignition to be turned "On", then the adapter begin connecting to car ECU. If the ignition is "Off" the moving string on your watch will look like: "Engine RPM: Searching...". This message is going from the ELM327 chip. If in 5 seconds it don't connect to ECU, you'll see "Unable to connect" (it appears for the very short time) and then "Searching..." again. It's better if your adapter is ELM327 compatible at error messages level, because the WOD app listens them and adjusts the timing parameters. Better launch the app after your Bluetooth adapter was powered already.
If you're unsatisfied with the app, just don't use it, uninstall it and please don't waste your costly time writing various nasty things in the feedbacks...
