DuPont presented new line of Bluetooth module, the module sets of heat-shrinkable tube, the module on the ON / OFF / WAKE pin is the enable pin, enabled by default, when pulled by an external (not less than the voltage signal VCC-0.5V) is closed module power output by high external MCU control module re-search, STATE state output pin for the LED, the output pulse is not connected, connect the output is high, by the MCU to determine the state, welcome buyers to buy!
The module power input with the anti-reverse function, power is not connected to the back of the anti-circuit power! Bluetooth module allows you to pass through the original serial device to use to get rid of the shackles of cable in the 10-meter range wireless serial communications. Use the module without the need to understand the underlying complexity of the Bluetooth protocol, as long as a few simple steps you can enjoy the convenience of wireless communications.
Bluetooth transmission module through AT commands only four, namely, testing communications, change name, change the baud rate, change the matching password, AT command must be from the TXD, RXD signal pin is set, the channel can not be set via Bluetooth. Send AT commands to the device can be various types of MCU (such as 51, avr, pic, msp430, arm, etc.) can also be computer via serial port (PC serial port connection or USB to serial port after the MAX232) to send.
Special Note:
- 1. The host module and slave module can not switch modes, only a single mode (master or slave)
- 2. The host module can only be paired HC06 slave module can not be paired connection between the host module, the module is not sorted out the host computer or mobile phone with Bluetooth and other Bluetooth-enabled device
- 3. The slave module with Bluetooth computer or cell phone with Bluetooth pairing part of the use of slave modules can connect, if the computer does not have a Bluetooth adapter, Bluetooth adapter you can buy our
- 4. The host module AT command module from the machine less than the AT + NAME command, the same as other instructions
- 5. The host module and slave module interfaces are 3.3V level, can be connected directly with a variety of TTL level serial port MCU (5V 1K resistor in series of MCU, please) direct connection, set the parameters you can use the USB to MCU or shop serial port, or increase the MAX232 serial conversion circuit of the computer
Tips:
- TXD: sender, usually expressed as its sender, then another when normal communications equipment RXD.
- RXD: Receive-side, generally expressed as their receiver, then another when normal communications equipment TXD.
- When normal communications will always take their devices TXD RXD!
- Spontaneous self-closing: As the name suggests, is to receive its own transmitted data is received their own TXD RXD, used to send and receive test itself is normal. Also known as loop-back test.
- Bluetooth connection is not convenient because the core board, so we put it in the end plate welding, plate on 3.3V LDO, in order to facilitate further demolition, only useful for welding the pin, leads to VCC, GND, TXD, RXD (TXD, RXD are 3.3V) to facilitate wiring, module key to re-search button, and ON / OFF / WAKE pin button leads to the foot, high output by the external MCU control module re-search, STATE state output pin for the LED, the output pulse is not connected connecting the output high, to judge by the MCU state, the module can be connected microcontroller, USB to serial devices such as serial port, input voltage 3.6 ~ 6V (recommended 5V, no more than 7V), Module size: 40 * 15.5 (mm).
CONTENIDO DEL ENVÍO (por cada unidad de compra):
