SPP-C Bluetooth module is designed for wireless data transmission, version V2.1+EDR Bluetooth. This module supports UART interface as well as SPP Bluetooth protocol.
Low cost, small size, high transmit/receive sensitivity, low power consumption, minimum external components and maximum capabilities.
Main characteristics:
Bluetooth Chip: BK3231
Communication protocol: Bluetooth Specification v2.1+EDR
Radius: up to 10 meters (power level 2)
Integrated PCB antenna
Compatible with all Bluetooth adapters that support SPP
Radio frequency: 2.40 .. 2.48 GHz
Host Interface: UART
Supply voltage: 3.3V
Power consumption during data transfer: 40 mA
The module is configured for UART speed - 9600 baud (8 data bits, no parity, stop bit (8N1)); the factory password is 1234. The module can only work in the Slave mode. The power supply of the module is 3.3 V, therefore, when used in conjunction with a 5V data line, a level converter is required. for exampleTXS0108E .
TX, RX - UART interface;
NC - reserved;
P00… P45 - programmable input/output port;
RESET - reset line;
3.3 V - power supply;
GND - ground.
Submission of AT commands must be accompanied by CRNL characters (they are/r/n, they are also 0x0D 0x0A - carriage return and line feed). The transition to the AT command mode occurs immediately after the module is powered up, and after the module is connected to the Bluetooth device, it already switches to the data transmission mode.
