This is a proof-of-concept for Power Meter Support in VivoActive. It has only been tested with the Rotor power meter so I am currently looking for more feedback regarding other devices' support. This application uses a module that I hope to implement in an upcoming release of ActiveMeter.

Please post any feedback and comments here: https://forums.garmin.com/showthread.php?318857-VivoPower-Power-meter-reading-for-VivoActive
Change log

0.1 - Initial release
0.2 - Added torque calculation where torque is not being returned from device
0.3 - Added new interface for number picker
0.4 - Removed zero value caused by when event count resetting to zero
0.4.1 - Removed code to double crank torque value
0.5 - Split data into individual screens - slide left/right to scroll between them. It may take up to 30 seconds for some screens (e.g. parameters may only be sent between every 120 other messages).
0.5 - Fixed issue with calibration not working

By default it will pair with the first device it finds. If you have multiple devices or wish to use this app around other riders it's recommended that you set the device id using the menus in the device. The device id can be reset later.

This has only been tested on crank based meters, wheel based meters may behave strangely or not at all. Please provide comments either way; I will set up a page in the forums for two way feedback soon.
