1. Introduction of Module HC-02
1.1 Features
HC-02 UART communication module which is developed based on Bluetooth standard SPP and
compatible with BLE, high stability and low power consumption. Users do not need to care about
complicated wireless communication configuration and transmission algorithm, only need to connect
to the device through TTL UART.
HC-02 slave module can be paired with mobile phones and connected for data transmission after
being powered on. In addition, it can be connected to the HC-05 or HC-06 master module (PIN code
is consistent, and default is 1234), which can replace a traditional serial port line, in this way, wiring
work is omitted and flexible use realized.
