توضیحات

ماژول بلوتوث HC-31 BLUETOOTH MODULE:

HC-31 is an upgraded version of the HC-06 Bluetooth module, which contains a base with a pin, enabling pin-in and patch-in-two embedded applications. The module supports 3.2 to 5.5 V. Command and use method with HC-06-.

products based on Bluetooth 2.0 version of the development, high stability, ultra-low power, industrial-grade Bluetooth digital transmission module. Users do not care about the complex wireless communication configuration and the algorithm, only need to connect the device through the TTL serial port, you can connect transparent data.

serial common sense

TXD: the sender, generally expressed as its own sender, must have normal communication connected to another RXD device.

RXD: the receiving end, generally expressed as their own receiver, the normal communication must be connected to another device TXD.

normal communication time TXD7 Bian remote device RXD!

Auto-RXD access to other equipment TXD, so if you want to receive their own data, their own TXD directly on the RXD, used to send and receive their own is normal, ii rapid vibration is simple test method when the problem occurs first do the test to determine whether the product failure. also known as walking test.

Module communication:

1 module (as slave), power, Andrews machine can Bluetooth search connection, for transmission.

2 modules (set one for the host, one for the machine, matching code consistent, the default are 1234, power on automatically connected pass) replace a traditional serial line, eliminating wiring work, the use of very flexible.

1 module is connected with the corresponding PC virtual serial port (HC-06-USB), and the connection between the two modules is the same.
Product Features

(1) Operating voltage: DC3.2 ~ 5.5V, working current of about 40mA, please do not supply less than 100mA.

(2) Interface type: UART (support 3.2-5.5V level ^ directly and 3.3V or 5V microcontroller serial communication. Module and 5V microcontroller communication without string resistance, do not provide 5V to 3.3V LDO, directly connected 5V power supply can.

(3) Communication: serial, full duplex, 8-bit data bits, 1 stop bit, support parity, support 1200 ~ 1382400bps communication baud rate. Users simply understand the serial communication, regardless of the Bluetooth communication protocol.

(4) working frequency band: 2.40 ~ 2.48 GHz, built-in PCB onboard antenna, the user can also adjust the capacitor location to use the sunset antenna.

(5) master-slave can switch the role through the AT command. As a host, you can communicate with other Bluetooth devices from the device. As a slave, you can communicate with your phone or other Bluetooth slave devices.

(6) onboard status light, the working status of the module at a glance.

(7) module size is 28.6mm x 15.24mm x 2mm, support pin and punch hole two welding methods, both for the convenience of new users use DuPont on the microcontroller serial port or PC serial port (USB serial device), but also convenient batch of users posted Production.

(8) module selection CSR BC417143 Bluetooth 2.0 chip, stable, 115200bps high baud rate when communication packets are not lost bytes.
