HC-06 Wireless Serial 4 Pin Bluetooth RF Transceiver Module RS232 TTL for Arduino
Arduino Bluetooth communication
Bluetooth (Bluetooth) technology, is a short-range radio technology, the use of «Bluetooth» technology that can effectively.
Simplify PDAs, notebook computers and mobile phone handsets and other mobile communication terminal communication between devices, but also to work.
1 Core module uses HC-06, leads from the module interface includes VCC, GND, TXD, RXD, reserve LED status output pin, the microcontroller can be judged by the foot state Bluetooth has connected KEY pin slave invalid.
2 led indicate Bluetooth connection status, flashing Bluetooth connectivity, lit the Bluetooth connection and open a port
Backplane 3.3V LDO input voltage 3.6 ~ 6V, current is about 30mA unpaired, paired about 10mA, the input voltage to prohibit more than 7V!
3 the interface level 3.3V, can be directly connected the various SCM (51, AVR, PIC, ARM, MSP430, etc.), the 5V MCU also can be connected directly, without MAX232 can not go through the MAX232!
4 open to the effective distance of 10 meters, over 10 meters is also possible, but not of this the quality of the connection of the distance do to ensure
5 after the pair when full-duplex serial port to use, do not need to know anything about the Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity communication format, which is the most commonly used communication format does not support other formats .
6 support for Bluetooth connection is not established by the AT command set the baud rate, name, passkey, set parameters are saved after. Bluetooth connection is automatically switched to the pass-through mode
7 compact (3.57cm * 1.52cm), the factory chip production to ensure the placement quality. And sets of transparent heat shrink tubing, dust and beautiful, and anti-static.
8 the link from the machine, computer, Bluetooth with Bluetooth function from the function with a variety of hosts, the majority with a Bluetooth-enabled cell phone, PDA, PSP and other intelligent terminal pairing from not pairing between the machine.
