I thought it would be cool (as well as nice to simplify) to consolidate my workout data (HR, Cadence, Mileage, etc.) from multiple bikes and self via an onboard wireless standard such as ant+ (currently using Garmin bike sensors and HRM belt), which of course the S3 provides no such support
.
Okay, fine, switch channels, what other wireless options exist that would allow me to do this, even if it meant obtaining other expensive sensors to make this work... Bluetooth! old semi-reliable Bluetooth! Problem solved... whoops, no, sensors I need are only through friggin BLE v4.0 which is apparently in this phone's chipset but has some bug in the software that makes it unusable, (and has been for a long time from what I can tell).
Given this, I can't find any options with this phone that will allow me to do this.
Anything else I may not be considering? This (and similar applications) would seem to be an obvious use for this contraption.
