The core module USES HC-06 Lord module, leads to interface including VCC, GND, TXD, RXD, STATE LED STATE output feet, microcontroller can through the STATE STATE judge whether have feet bluetooth connection, on the module set to resume the search button, and lead to the KEY feet for external use single chip microcomputer.
Led instructions bluetooth connection state, flash said not matching, slow flash has expressed a but not currently and matching connection from the machine,The light has been said already follow Slave links.
Floor set counter-attack by diode, with 3.3 V LDO, input voltage of 3.6 ~ 6 V, not matching current about 30 mA, paired about 10 mA, input voltage banned more than 7 V.
Interface level 3.3 V, can be directly connect all kinds of single chip (51, AVR, PIC, ARM and MSP430 etc), 5 V microcontroller can also be connected directly, can not have the MAX232.
A clearing effective distance 10 m, more than 10 m is possible, but not to this distance connection quality of the guarantee.
Only HC06 from machine matching, between host also cannot pair.
