The future is looking promising for a lot of fitness trackers.
The rise of fitness apps and smartwatches like Fitbit, Jawbone, and Apple Watch are all fueling an explosion in wearable devices.
But there’s one gadget that’s been quietly taking over the fitness market: a treadmill.
That’s right: a fitness tracker.
The Fitbit Surge 3 is the most recent fitness tracker to hit the market.
The device’s $199 price tag is a big deal for most people, but the Surge 3 has one major drawback: the device’s battery is pretty much dead.
The Surge 3 uses Bluetooth LE to communicate with other smartwrist-controlled devices like Fitbits and Jawbone trackers and Garmin Connect fitness trackables, but that’s about it.
Fitbit’s Surge 3 only has Bluetooth LE connectivity on the front panel, and the rest of the device relies on a single button.
FitBit has confirmed to Recode that the Surge 2 has Bluetooth connectivity on both the front and back panels, and that the company is working on making the Surge even more Bluetooth-enabled, according to an email sent to Recineagle readers.
This means that Fitbit can offer an additional pair of eyes on your wrist in case you lose your phone.
Fitbits Surge 2 uses a pair of infrared sensors on the back panel to track your steps and steps per minute, and it has a built-in accelerometer to help keep your fitness tracker connected to your phone even if you’re out of range.
Fitbits Surge 2 can also connect to Garmin Connect and Jawtech Fitmobil devices, but only with the Fitbets proprietary Bluetooth LE protocol, which is proprietary to Fitbit.
Fitbite, Jaw, and Fitbit are working to roll out support for other Bluetooth LE devices, including Apple Watch and the Samsung Gear Live, but until they do, you’re stuck with the Surge’s lackluster Bluetooth connection.
The best part?
Fitbit said that if the Surge was going to be an option for people to buy, the company would make it compatible with all of these smartwitness-enabled fitness trackors.
This is great news for anyone looking to upgrade from a fitness tracker that requires Bluetooth LE.
The Fitbit Verge 2 has both Bluetooth LE and Bluetooth 3.0 connectivity, but its battery life is less than the Surge, at about five hours of continuous use.
And Fitbit isn’t the only one trying to make Bluetooth LE available to smartwars.
The Google Fit, Fitbit Flex, and Samsung Gear 360 all support Bluetooth LE, but each of these devices can only connect to smartwatch-style apps like Apple Watch, Fitbills fitness tracker, and Jawboots smartwatch.
Fit and Jaw aren’t the first companies to announce support for Bluetooth LE for fitness trackable devices.
Other fitness track trackers like Garmin Connect, Fitbits, Jawboks, and Microsoft’s Xbox One S have all been shipping with Bluetooth LE on their front panels since 2013.
These trackers work with a wide variety of apps and wearables, and most of these apps are compatible with Bluetooth 4.1 LE.
But for those who want to run an app that only works with Bluetooth 2.1, Bluetooth 3 is still the best way to go.
Bluetooth 4 is much more powerful than Bluetooth 2, and Bluetooth 4 LE is the future.
Bluetooth LE lets your phone do most of the heavy lifting for you when it comes to communicating with Bluetooth devices.
Bluetooth 2 is the older protocol, and because it only has two levels of data, Bluetooth 2 can only work with apps that support the older, weaker protocol.
Bluetooth 3, on the other hand, is a much faster, more powerful protocol that supports all Bluetooth devices, so it can support a wide range of apps.
And Bluetooth LE is so powerful that it can be used to communicate wirelessly with multiple devices, even if each of those devices is connected to a different Bluetooth LE adapter.
So for a while, Bluetooth LE was the only way to send messages to your smartphone without a Bluetooth connection, but now it’s all about Bluetooth 3 and LE.
There are a few reasons why this could be good news for people who want a fitness-focused smartwatch with Bluetooth.
First, Bluetooth is much faster.
Bluetooth is able to process more data than Bluetooth, which means it can process a lot more data at once.
The Bluetooth LE connection will only be available for apps that use the weaker protocol, so you won’t be able to send a message that doesn’t rely on a Bluetooth 2 connection.
For instance, if you only have one Bluetooth LE enabled app on your watch, you’ll only be able send a single message at a time.
Bluetooth doesn’t support the slower protocol, meaning you can send multiple messages to the same Bluetooth LE-enabled device.
This makes Bluetooth 2 more powerful and useful for apps like Microsofts Xbox One, but Bluetooth LE still doesn’t provide the speed and responsiveness that Bluetooth 2 does. For that
