Host and slave
The host can only match from the machine, can not match the phone, computer and so on, also can not be searched,For two devices directly through the Bluetooth serial communication, such as between single chip microcomputer and single chip microcomputer, the use of methods and serial port;
From the function with a variety of Bluetooth function of the computer, Bluetooth host, most with Bluetooth mobile phone, PSP, PDA and other intelligent terminal pairing, from the machine can not match.
Between the host and from the machine can only one pair of one.
1, the core module uses HC-06 from the module, the extraction interface includingVCC,GND,TXD,RXD
2. LED indicates the status of the Bluetooth connection,The flashing indicates no Bluetooth connection, which is often said to have been connected and opened the port.
3, floor setAnti reverse diode, with LDO 3.3V,The input voltage is 3.6~6V, the current is about 30mA, and the pairing is about 10mA,Input voltageExceed 7V!
4, interface level 3.3V, can be directly connected to a variety of single-chip (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontroller can also be directly connected
5,An open and effective distance of 10 meters (power rating of CLASS 2),Do not exceed the connection quality of this distance to make the guarantee
6, after pairingFull duplex serial portUse, support from1200BPS ~ 1382400bpsAmong the commonly used baud rate (see manual), without any knowledge of the Bluetooth protocol, only support8 bit data bit, 1 bit stop bit (parity check can be set)The communication format, which is also the most common form of communication, does not support other formats.
7, only inNo Bluetooth connection is established (that is, LED).When supported by the AT instruction set the baud rate, name, pairing password,Set the parameters of the power down save. Automatically switch to the AT command after the Bluetooth connection.
8, compact size(3.57cm*1.52cm),FactoryPatch production, guarantee the quality of the patch. A transparent heat shrinkable tube, dust-proof beautiful but also anti-static.
9, the current version of the latest version number isV1.06, TXD, RXD, the protection circuit,Greatly reduce the risk of damage to the pin
9,The link is from machine,From the function with a variety of Bluetooth function of the computer, Bluetooth host, most with Bluetooth mobile phone, PSP, PDA and other intelligent terminal pairing, from the machine can not match.
Special alert:Normal communication requires that the RXD pin of the device to be connected with the device must be brought on the pull function if the USB chip is used for the PL2303HX to communicate with it (including sending AT commands), please in PL2303HXRXD pin on the power supply is connected to a 10K or so! Remember!! Or buy the shop USB to serial port
Paired only need as the serial baud rate is fixed as can be used, so as long as it is to & ldquo; baud rate is fixed, 8 data bits, no parity & rdquo; communication format of serial device can directly replace the original wired serial without the need to modify the program. Such as data acquisition, intelligent vehicle, serial printer, outdoor dot matrix screen control, etc..
Paired with computer:For the computer and equipment through the Bluetooth serial communication, using the method and the serial port
Paired with mobile phones:For mobile phones and devices through the Bluetooth serial communication, using the same method and serial port
Paired with Bluetooth host:For two devices directly through the Bluetooth serial communication, such as between single chip microcomputer and single chip microcomputer, the use of methods and serial port
Baud rate transform, because the sender and the receiver can choose their own baud rate, when a small amount of data can be used as a baud rate transform equipment.
