Because of its low power and short data transmissions, it is great for transmitting bite size information, but not great for streaming data such as sound or video Good luck and enjoy! Section Conventions Used in this Book Every developer has their own coding conventions I personally believe that well-written code is selfexplanatory Moreover, consistent and organized coding conventions let developers step into each other’s code much more easily, enabling them to reliably predict how the author has likely organized and implemented a feature, thereby making it easier to learn, collaborate, fix bugs and perform upgrades The coding conventions I used in this book is as follows: Inline comments are as follows: // inline comments Multiline comments follow the JavaDoc standard: /** * This is a multiline comment .. .Bluetooth Low Energy in Android Java 1st Edition Tony Gaitatzis BackupBrain Publishing, 2017 ISBN: 978-1-7751280-1-4 backupbrain.co Bluetooth Low Energy in Android Java by Tony Gaitatzis...
