1. The core module HC-06 main modules, leads the interface includes
VCC, GND, TXD, RXD, KEY pin high trigger to clear the pairing
information re search
2. led indicate Bluetooth connection status, flash unpaired slow
flash indicates paired but not slave connection, Always follow
3. Backplane settings LDO input voltage of 3.6~~6V unpaired current
is about 30mA, paired 10mA, input voltage prohibit more than 7V
absolute prohibition of reverse power!
4. 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!
5. Open to 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
6. The pair later when full-duplex serial 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.
7. Support to establish a Bluetooth connection through AT commands
set the baud rate, passkey, set parameters are saved after.
Bluetooth connection is automatically switched to the pass-through
