Fully Qualified Bluetoothv2.1+EDR. Compliant with v2.0.E.2 of specification for both 2Mbps and 3Mbps modulation modes. Bluetooth module as a wireless alternative to cable, between serial devices (Interface with UART) and Bluetooth Devices establish Bi-directional Data transmission channel. Bluetooth module can be set to master or slave role. The Master module can search for other Bluetooth devices and can Initiate a connection. The Slave module can only passively accept the connection. Bluetooth module has two operating modes: AT command response mode and auto-connect mode. When the module is in AT command response mode. The MCU can send all kinds of AT commands to the module through UART interface for set the operating parameters of the module. When the module is in auto-connect mode, it will initiate the connection (Master Role) or into a connected state(Slave Role). Applications: Medical equipment data collection and transmission Bluetooth wireless data transmission Bluetooth wireless industrial control Bluetooth RS232/485 transfer Bluetooth joystick, bluetooth game pad Bluetooth printer / Bluetooth Scanner / barcode device Bluetooth remote control toy Bluetooth GPS navigation Bluetooth wireless instrument and meter Technical Documentation: 1.”the HHW-UART-S1800 Module Operating Manual” 2.”the HHW-UART-Sx Module AT command set” Warranty: 7*24hs email customer support vivis-eur@vitebo.com ## Features - Full compliance with Bluetooth V2.1 + EDR specification; Bluetooth class 1 levels, Transmission coverage up to 100~1800m.
