the core module uses HC-05 from the module, leading interface including VCC, GND, TXD, RXD, Reserved LED state output foot, the microcontroller can determine whether Bluetooth is connected through the foot state,KEY pin to the machineinvalid
led indicates Bluetooth connection status, flashing indicates that there is no Bluetooth connection, always bright indicates that Bluetooth is connected and open port
base plate 3.3V LDO, input voltage 3.6 to 6V, when not paired current about 30mA, after pairing about 10mA, input voltage No more than 7V!
interface level 3.3V, can be directly connected to a variety of microcontrollers (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontroller can also be directly connected, no MAX232 can not go through the MAX232!
open effective distance of 10 meters, more than 10 meters is also possible, but do not guarantee the connection quality of this distance
pairing after when full duplex port use, do not need to know any Bluetooth protocol, but only support 8 bits of data bits, 1 bit stop bit, no parity of the communication format, which is also the most common communication format, does not support other formats.
in the absence of a Bluetooth connection support through the AT instructions to set the Baud rate, name, pairing password, set the parameters of power-down save.
Bluetooth connection later automatically switched to transmission mode
small size (3.57cm x 1.52cm), factory patch production, to ensure patch quality. And set transparent heat shrink tube, dust-proof beautiful, and have a certain anti-static capacity. 9, the link is from the machine, from the function and a variety of Bluetooth-enabled computers, Bluetooth host, most of the mobile phones with Bluetooth, PDA, PSP and other smart terminal pairing, from the machine can not be paired.
