bluetooth vs ble

Objective:Apple starts to support ble 4.0,iphone4s,ipod 5,ipad after iOS 6 system After the 3 model starts to embed BLE4.0 hardware, so before development, please confirm that your development environment meets the above requirements, and Apple after BLE4.0, the external connection device is no longer required MFI certification, of course, your peripherals must have Bluetooth 4.0 moduleReview:To develop the

). Then we remove any unnecessary status bits. The calculation method comes directly from the Sensortag document.To show this data on the interface, we use the arg1 and arg2 two member variables of the Message, and we multiply it by 100 before converting it to the desired int value. After that, we'll divide by 100 to return a float value. As before, the code for the UI will not be shown here, but it will be in the source code.If we run the program, we can see the Celsius temperature and humidity

The Bluetooth mouse we purchased last week has been back. fortunately, it was the first time I used a wireless mouse.
