ماژول بلوتوث HC-04
This small and cheap CSR BC417143 based wireless Bluetooth transceiver module is widely used in many kinds of embedded projects. It is intended for serial communication and preloaded with serial port profile (SPP) firmware.
The module has user configurable parameters like Device name, Pairing PIN and Serial speed. In most cases the default values of these parameters should be changed (at least Pairing PIN code) to suit your application. It is done by entering special AT commands when the module is not remotely connected to any other bluetooth device.
Note: This bluetooth module can only act as a receiver module.
