HC-06 Bluetooth serial pass-through module wireless serial communication from machine Wireless HC06 for arduino Bluetooth Module Special attention; the following are the wrong connection method: The following is not a product quality problems, are caused by wiring errors, not warranty is not returned: 1, since the spontaneous test after the success of the use of TXD or RXD caused by short circuit 2, the module connected to the power supply caused damage This module is as a foreign trade export, students and electronic enthusiasts to buy this module first to consider clearly, this can not be back can not change, do not burn when the time is that our quality problems to return or replacement, before shipment All have a good test Product Features: 1, the core module using HC-06 from the module, leads to the interface, including VCC, GND, TXD, RXD, reserved LED status output pin, the microcontroller can determine whether the state of the Bluetooth has been connected, KEY pin on the machine invalid 2, led instructions Bluetooth connection status, flashing that there is no Bluetooth connection, light means that Bluetooth is connected and open the port 3, the bottom plate 3.3V LDO, the input voltage of 3.6 ~ 6V, unpaired current of about 30mA, about 10mA after pairing, the input voltage is prohibited more than 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, no MAX232 can not go through MAX232! 5, open to the effective distance of 10 meters, more than 10 meters is also possible, but not the distance to ensure the quality of the connection 6, after the match when the full-duplex serial port, no need to understand any Bluetooth protocol, but only supports 8-bit data bits, 1 stop bit, no parity communication format, which is the most commonly used communication format, does not support other formats The 7, in the absence of a Bluetooth connection to support the AT command to set the baud rate, name, matching password, set the parameters of power-down save. Bluetooth connection automatically switches to transparent mode Little common sense (very important): TXD: the sender, generally expressed as their own sender, the normal communication must be connected to another device RXD. RXD: the receiving end, generally expressed as their own receiver, the normal communication must be connected to another device TXD. Normal communication when the TXD itself automatically connected to the device RXD! Auto-RXD access to other equipment TXD, so if you want to receive their own data sent by name, that is, to receive their own data sent, that is, their own TXD directly connected to the RXD, used to test their own send and receive Whether it is normal, is the fastest and easiest test method, when the problem occurs first to do the test to determine whether the product failure. Also known as loop test.
