Features:
Core module HC-06, leads to interface includes VCC, GND, TXD, RXD, aside
LED status output pin, the microcontroller via the pin state judge
whether Bluetooth connection, KEY pin on the slave invalid
Led indicate Bluetooth connection status, flashes indicates no Bluetooth
connection, Always indicate the Bluetooth port is connected and turned
on Backplane 3.3V LDO, the input voltage 3.6 ~ 6V, unpaired when the
current approximately 30mA, paired about 10mA, the input voltage must
not exceed 7V!
interface level 3.3V, you can directly connect a variety of SCM (51,
AVR, PIC, ARM, MSP430, etc.), 5V microcontroller can also be directly
connected, it can not pass without MAX232 MAX232!
full-duplex serial port to use later, when paired, without knowing any
Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity
communication format, which is the most common communication format,
not support other formats .
In the Bluetooth connection is not established when setting the baud
rate supported by AT commands, names, matching password, set the
parameters of power down to save. After the Bluetooth connection
automatically switches to transparent mode
