I guess my previous reply covers some of this. We have not made any comparisons to SPP, no.ģ. In other words it is risky to make assumptions about throughput if you want to support a large number of devices. The fastest phones we have seen max out at about 1200 kbps, and most of them are significantly slower. If you use Nordic devices on both sides of the link you should be able to get close to these values, but when connecting to other equipment (like phones or PC's) there could be other limitations in place. Bluetooth 4.0 maxed out at approximately 128 kbps, Bluetooth 4.2 increased this to ~760 kbps, and Bluetooth 5 increased this again to ~1360 kbps when using the 2Mbps high speed mode. Then you are also free to make other changes to the service, such as adding or removing characteristics.Ģ. Instead they made it very easy to make your own custom services, by using the GATT protocol in BLE.įor evaluation and prototyping you can use the NUS service freely, but if you are planning to make a product based on it you should change the base UUID to something unique. The Bluetooth SIG wanted to avoid a situation like SPP where thousands of different devices send wildly different types of information over the exact same service, because it devalues the point of having a service in the first place. The Nordic UART service (NUS) is meant as an alternative to SPP for applications where you want to exchange custom information between devices, but because BLE makes it very easy to create your own profiles and services the UART service is only meant as an example of how you can make a proprietary service, and is not meant to be used directly in end products. Bluetooth LE just needs to connect to the device to read/write information.1.
The protocol is limited up to 7 slaves.
Technology based on standard Bluetooth profiles (SPP, DUN, PAN).Commonly used on cars, Handsfree profile.Not suitable for certain devices such as wereables.
Useful for applications with data streaming because it achieves greater throughput than Bluetooth LE technology.For more information, see Apple Developers: MFi Program.Ĭlassic Bluetooth vs Bluetooth Low Energy Image by the the Bluetooth SIG. The reason is that only hardware manufacturers are given access to the SDK for Classic Bluetooth. RTL does not support Classic Bluetooth on iOS. *Windows Server does not support Bluetooth (see: General Bluetooth Support in Windows).įor macOS and iOS, BluetoothLE is only supported on the following hardware: 2 Classic Bluetooth vs Bluetooth Low Energy.
