This module is an HC-06 module, which is in slave mode. The mode of the module has been set at the factory, so the mode of the module cannot be changed.
Warm reminder: Do not connect the power supply to the signal pin, it will directly burn the module! The input voltage is prohibited to exceed 7V!
Factory direct sales, it is safer to use heat shrink tube to prevent static electricity, and the quality of the static bag
remains unchanged. HC-06 Bluetooth slave module
delivery list
A special note for the HC-06 Bluetooth board
; the following are all wrong connection methods:
the following situations are not product quality problems, they are all caused by wiring errors, and will not be returned or exchanged without warranty:
1. Self-collection After the spontaneous test is successful, TXD or RXD is short-circuited to ground during use.
2. The module is damaged due to reverse power supply.
This module is used as an outlet. Students and electronics enthusiasts must consider it carefully before purchasing this module. This module cannot be returned or exchanged. , don’t let us return or exchange the goods if they burn out and say it’s our quality problem. Everything has been tested before shipment.
Product Features:
- 1. The core module uses the HC-06 slave module. The lead interfaces include VCC, GND, TXD, RXD, and the LED status output pin is reserved. The microcontroller can judge whether Bluetooth is connected through the status of this pin. The KEY pin is invalid for the slave machine.
- 2. The LED indicates the Bluetooth connection status. Flashing means there is no Bluetooth connection. Steady light means Bluetooth is connected and the port is open.
- 3. Baseboard 3.3V LDO, input voltage 3.6~6V, current is about 30mA when not paired, about 10mA after pairing, input voltage is prohibited to exceed 7V!
- 4. The interface level is 3.3V, which can be directly connected to various microcontrollers (51, AVR, PIC, ARM, MSP430, etc.). 5V microcontrollers can also be directly connected, without MAX232 and cannot pass through MAX232!
- 5. The effective distance in open space is 10 meters. It is possible to exceed 10 meters, but the connection quality at this distance is not guaranteed.
- 6. After pairing, it will be used as a full-duplex serial port. There is no need to understand any Bluetooth protocol, but it only supports the communication format of 8 data bits, 1 stop bit, and no parity check. This is also a commonly used communication format and does not support other formats. .
- 7. When a Bluetooth connection is not established, it supports setting the baud rate, name, and pairing password through AT commands, and the set parameters are saved after power off. Automatically switches to transparent transmission mode after Bluetooth connection
- 8. Small size (3.57cm*1.52cm), factory patch production to ensure patch quality. It is also covered with transparent heat shrinkable tube, which is dust-proof and beautiful, and has certain anti-static capabilities.
- 9. This link is a slave machine. The slave machine can be paired with various computers with Bluetooth functions, Bluetooth hosts, most mobile phones with Bluetooth, PDAs, PSPs and other smart terminals. Slave machines cannot be paired with each other.
Little common sense (very important):
- TXD: Transmitter, generally represented as your own transmitter. Normal communication must be connected to the RXD of another device.
- RXD: Receiving end, generally represented as your own receiving end. Normal communication must be connected to the TXD of another device.
- During normal communication, your own TXD is always connected to the device's RXD!
- Self-transmitting: During normal communication, RXD is connected to the TXD of other devices. Therefore, if you want to receive the data sent by yourself, as the name implies, you will receive the data sent by yourself, that is, your own TXD is directly connected to RXD to test your own sending and receiving. Whether it is normal or not is a simple test method. When a problem occurs, do this test first to determine whether the product is faulty. Also called loopback testing.
