Master is a term used in network technology. In a network, a master is a device that prompts other devices (slaves) to perform a
specific task such as receiving or sending data. In an SMA Bluetooth network, all SMA communication products (e.g., Sunny Ex-
plorer, Sunny Beam with Bluetooth, etc.) are master devices.
