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.
Applications
