Bluetooth Modem Transeiver RF Minimum pass-through Wireless Module Slave
Product Description
1. The core module uses HC-06 as a slave module, with interfaces including VCC, GND, TXD, RXD, and reserved LED status output pins. The microcontroller can determine whether Bluetooth is connected based on the status of this pin, and the KEY pin is invalid for the slave
2. LED indicates Bluetooth connection status, flashing indicates no Bluetooth connection, constant light indicates Bluetooth is connected and the port is open
3. Bottom board 3.3V LDO, input voltage 3.6-6V, unpaired current about 30mA, paired current about 10mA, input voltage must not exceed 7V!
4. The interface level is 3.3V, which can be directly connected to various microcontrollers (51, AVR, PIC, ARM, MSP430, etc.), and 5V microcontrollers can also be directly connected without MAX232 and cannot pass through MAX232!
5. The effective distance of open space is 10 meters, and it is also possible to exceed 10 meters, but the connection quality at this distance is not guaranteed
6. After pairing, when using a full duplex serial port, there is no need to understand any Bluetooth protocol, but only supports communication formats with 8-bit data bits, 1-bit stop bits, and no parity check. This is also the most commonly used communication format and does not support other formats.
7. Support setting baud rate, name, and pairing password through AT command when Bluetooth connection is not established, and save the set parameters in case of power failure. Automatically switch to transparent mode after Bluetooth connection
8. Compact size (3.57cm * 1.52cm), factory patch production ensures patch quality. Equipped with transparent heat shrink tubing, it is dust-proof and aesthetically pleasing, and has a certain anti-static ability.
9. This item is for the slave, which can be paired with various Bluetooth enabled computers, Bluetooth hosts, most Bluetooth enabled mobile phones, PDAs, PSPs, and other smart terminals. The slave cannot be paired with each other.
Small common sense (very important):
TXD: sender, usually referred to as one's own sender, normal communication must be connected to another device's RXD.
RXD: Receiver, usually referred to as one's own receiver, must be connected to another device's TXD for normal communication.
During normal communication, the TXD itself is always connected to the RXD of the device!
Self receiving and spontaneous: During normal communication, the RXD is connected to the TXD of other devices. Therefore, if you want to receive data sent by yourself, as the name suggests, it means that your own TXD is directly connected to the RXD to test whether its transmission and reception are normal. This is the fastest and simplest testing method. When a problem occurs, the first step is to perform this test to determine whether the product is faulty. Also known as loop testing.
