BLUETOOTH SERIAL CONVERTER UART INTERFACE 9600BPS USER’S GUIDE

Chapter1. Bluetooth Serial Converter UART Interface 9600bps Key Features — — — — — — — — — — —

Bluetooth Spec v2.0+EDR Compliant Enhanced Data Rate (EDR) compliant with V2.0.E.2 of specification for both 2Mbps and 3Mbps modulation modes Class 2 Type Output Power Full Speed Bluetooth Operation with Full Piconet Support Scatternet Support 3.3V Operation Minimum External Components UART Interface Support for 8Mbit External Flash Onboard Support for 802.11Co-Existence RoHS Compliant

Product Description GL-6B is a Class 2 Bluetooth module using BlueCore4-AudioROM chipset from leading Bluetooth chipset supplier Cambridge Silicon Radio. This converter is used to convert a UART with 9600bps, one start bit, 8 data bits, one stop bit, no parity bit format to Bluetooth UART protocol. It can not talk to a same device but only to PC Bluetooth dongle. That is, it will create communication between an embedded microcontroller and a PC, but not between 2 embedded devices. For the password, normally it doesn’t need a password, when PC could find the converter, just double click it and the connection will be created. If it requests you to input password all the same, it shall be 0000 or 1234.
