So why is there excitement over BLE instead of ANT+, if they do the same thing? One, and only one reason: Cell phones.Īs dedicated health and fitness devices have rapidly been swallowed by cell phones for many users, the future is sensor devices that work seamlessly with your cell phone and compatible apps. In that respect, it’s from a consumer standpoint virtually identically to ANT+ compatible sensors (such as what is used in your Garmin accessories), which offer roughly the same battery life. Unlike your wireless headset that requires near-daily charging, BLE devices are meant to be low-energy, and typically run instead on simple replaceable coin cell batteries that can last a year or more.

However, BLE devices are very different from standard Bluetooth accessories in one key area: battery consumption. You’ve probably used Bluetooth devices in the past, such as wireless headphones. I previously noted the ever confusing naming scheme that the Bluetooth SIG has come up with, so we’ll just focus on the low energy aspect for now.
Bluetooth Low Energy has been called a number of things over the years, from BLE/BTLE (Bluetooth Low Energy) to now more recently, Bluetooth Smart. See, Blue HR is the very first consumer Bluetooth Low Energy sensor device. And that difference is key in understanding what may be the tip of the iceberg for a shift in health and fitness technology for years to come. But, while the just announced Wahoo Fitness Blue HR may look virtually indistinguishable from every other HR strap out there – it’s an entirely different beast under the hood.
You may be wondering why exactly I’d be reviewing a single heart rate (HR) strap – after all, they are fairly common, and all largely do the same thing: Read your heart rate.
