,,, /*************************************** ************************** *************************** 1. permissions and related attributes are the most basic. 2. initialize Bluetooth. This method can generally be written in the startup activity of the project. Otherwise, you may not need to manually open the Bluetooth after writing the ble code and find it

As the accessory of mobile communication, choose Traditional Bluetooth (Classic BT) and low power consumption Bluetooth (BLE) to compare and discuss the process; First clear our function is to use mobile phone with the attachment of communication, to achieve mobile viewing status (data Flow direction: Accessories-> mobile phone), and control accessories (data flo

device supports BLE feature (required is false), and you need to confirm that Bluetooth is turned on. If you find that BLE is not supported, you cannot use BLE-related features. If BLE is supported, but Bluetooth is not turned on

, the activity tracker naturally becomes the server side, and if the activity tracker needs to get updated information from an Android device, the Android device might be more appropriate as the server side.
