Bluetooth Modem
From Wiki
Introduction
The Bluetooth Modem is the latest Bluetooth wireless serial cable! This version of the popular Bluetooth uses the HC-05/HC-06 module. These modems work as a serial (RX/TX) pipe. Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target.
The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer. You can either solder a 6-pin header or individual wires.
- Model: BTH-07

Cautions
- Be paired must Master devices and Slave devices each other.Master and Master devices, Slave and Slave devices can't paired each other. The HC-06 Slave mode could paired with PDA, PC etc.
- Do not over 6 voltage

Specification
Pin definition and Rating
Pin definition and Rating
| Pin | # | Pad Type | Description |
|---|---|---|---|
| KEY | 1 | CMOS input with weak internal pull-up | HC-05 for into AT mode, HC-06 for clear paired information |
| VCC | 2 | 3.3V | Integrated 3.3V(+)supply with on-chip linear regulator output within 3.15-3.3V |
| GND | 3 | VSS | Ground port |
| TXD | 4 | CMOS output,tri-stable with weak internal pull-up | Asynchronous data output (UART Transmit) |
| RXD | 5 | CMOS input with weak internal pull-up | Asynchronous data input (UART Receive) |
| STATUS | 6 | CMOS output with weak internal pull-up | LED output status, and Bluetooth is not connected then output pulse, If Bluetooth connectivity, the output is high. It to judge state by the MCU |
