    1. Introduction 1. Introduction The TWN4 MultiTech 2 BLE Module is a configurable Reader/Writer of RFID transponders. This addition to the TWN4 family offers the Bluetooth Low Energy (BLE) interface. The Module has both the low (125kHz, 134.2kHz) and high (13.56MHz) frequency antennas, allowing the User access to a wide range of RFID standards.

    (GATT). GATT defines two roles: Server and Client. A GATT Server stores attributes of the device and sends them to a Client upon request. The TWN4 MultiTech 2 BLE acts as a GATT server, receiving re- quests for information from the link partner (ex. cellphone) and transmitting relevant attributes back.

    4. Power states and current consumption breakdown The TWN4 MultiTech 2 BLE supports 3 power states that can be used to reduce the current consumption of the reader when the application calls for it. In Normal state the reader can accommodate a request to search for a high-/low-frequency tag, perform a BLE action or interact with peripherals on short notice;...
