+ | ===UART Multiplexer (For free UART connection setting)=== | ||
+ | You can use the jumper to connect the TXD and RXD pins of HC-05 to | ||
+ | D0, D1, D4~D7 pin of Arduino. | ||
+ | |||
+ | [[File:ITEAD BT SHIELD (MASTER SLAVE)2.jpg]] | ||
+ | |||
+ | When using the connection as Figure 3, the BT [[shield]] connects to the | ||
+ | ATMega328 chip on board. | ||
+ | |||
+ | [[File:ITEAD BT SHIELD (MASTER SLAVE)3.jpg]] | ||
+ | |||
+ | When using the connection as Figure 4, the HC-05 connects with the | ||
+ | FT232RL chip, and the FT232RL connect to PC by USB. Whit this | ||
+ | configuration you can use the serial software on PC to control or | ||
+ | configure the HC-05 module. | ||
+ | |||
+ | [[File:ITEAD BT SHIELD (MASTER SLAVE)4.jpg]] | ||
+ | |||
+ | Except the 2 configurations above, you can connect the TXD and RXD | ||
+ | to any other pins from D4-D7, and using the software-serial library to | ||
+ | control the HC-05 module. | ||
+ | |||
+ | [[File:ITEAD BT SHIELD (MASTER SLAVE)5.jpg]] | ||
+ | |||
+ | ===Mode Switch=== | ||
+ | The Mode Set Switch is connected to PIO11, when it is pushed to CMD | ||
+ | and powered on, the HC-05 enter command mode, HC-05 module can | ||
+ | receive and response AT command in this mode. When it is pushed to | ||
+ | DATA and powered on. The HC-05 enters data mode and will not | ||
+ | accept AT command. | ||
+ | |||
+ | ===States LED=== | ||
+ | When power on and disconnect the port, states LED blinks 1time/2s ; | ||
+ | when the module connect and open the serial port, states LED blinks | ||
+ | 2times/s. | ||

Hardware
UART Multiplexer (For free UART connection setting)
You can use the jumper to connect the TXD and RXD pins of HC-05 to D0, D1, D4~D7 pin of Arduino.
When using the connection as Figure 3, the BT shield connects to the ATMega328 chip on board.
When using the connection as Figure 4, the HC-05 connects with the FT232RL chip, and the FT232RL connect to PC by USB. Whit this configuration you can use the serial software on PC to control or configure the HC-05 module.
Except the 2 configurations above, you can connect the TXD and RXD to any other pins from D4-D7, and using the software-serial library to control the HC-05 module.
Mode Switch
The Mode Set Switch is connected to PIO11, when it is pushed to CMD and powered on, the HC-05 enter command mode, HC-05 module can receive and response AT command in this mode. When it is pushed to DATA and powered on. The HC-05 enters data mode and will not accept AT command.
States LED
