It shouldn't be a surprise that Apple manufactures keyboards designed to complement their computers. So we invite you to share your comments on these or other models to help others trying to decide what to buy. Just like with apps and web resources, it's almost impossible to work with or even hear about every example or even every type of Bluetooth keyboard, let alone every model. As someone who's dabbled with Bluetooth keyboards since the addition of external keyboard support hit iOS, I've handled my fair share of these accessories in both my role as an assistive technology instructor and just a tech enthusiast on the internet. The Bluetooth SIG imagined homes and businesses full of IoT devices, and engineered the Bluetooth 5 spec to make them more powerful, useful, and easier to connect to.As the power and versatility of iOS devices sinks in, many users invariably ask veteran iPhone and iPad enthusiasts about Bluetooth keyboards. That means, essentially, eight times as many connected devices. For example, it brings an eightfold increase in broadcast data efficiency. That’s why it is used so often in Internet of Things devices, beacons, tiles, fitness trackers, and anywhere where really long battery or low-power operation is key.īluetooth 5 adds enhancements to low energy operation in addition to the optional higher-bandwidth or longer-range connections. As of Bluetooth 4.2, the BLE mode transmits a lot less data than classic Bluetooth, but it has similar range, much lower latency, and uses just a fraction of the power. First introduced in Bluetooth 4.0 and then improved in the v4.1 and v4.2 releases, BLE is a whole separate protocol from “classic” Bluetooth. Nearly all of the big improvements in Bluetooth 5 are exclusively for its Low Energy mode (BLE). Sadly, Bluetooth 5 does not include a standard audio transmission protocol within the low energy spec, so for the time being, bluetooth headphones and headsets will continue to use the more battery-draining Bluetooth Classic modes. It also means that we may one day see Bluetooth headphones that use the low-energy spec, which could massively increase battery life. This is great news for devices that need to transmit bursts of large amounts of data (like a firmware update) or for data-hungry applications like audio or video. In other words, the new Bluetooth version offers two interfaces for low energy operation: one to transmit less data over much longer distances, and one to transmit twice the data over a shorter range. This new physical layer (PHY) supports speeds of up to 2 megabits per second and higher transmission power of +20dB in low energy mode. In addition to the capability to sacrifice bandwidth for greatly extended range, Bluetooth 5 adds a new interface to double bandwidth at the expense of power. But it’s perfect for many Internet of Things (IoT) devices, which often transmit small amounts of data but need to reach all over a house or a large store. ![]() Developers have to consciously choose to sacrifice total bandwidth for range. You won’t get that kind of range all the time on all devices, mind you. ![]()
