The Serial peripheral interface data output The Serial peripheral interface data inputĬhip select for the serial peripheral interface, active low Input debounced must be low for >5MS to cause a resetĬMOS output, tri-stable with weak internal pull-up Programmable input/output line, control output for PA Programmable input/output line, control output for LNA Integrated 3.3V supply with On-chip linear regulator output within 3.15-3.3V HC-05 Breakout Board Pinout: HC-05 Breakout board pinout In this mode, the module is used for communicating with other Bluetooth devices i.e. To select either of the modes, we need to activate the Command Mode and sent the correct AT Commands. We can also use it to set HC-05 as a master or slave. This includes the firmware information, changing Baud Rate, changing module name, etc. In Command Mode, we can communicate with the Bluetooth module through AT Commands to configure various settings and parameters of the Module. The HC-05 Bluetooth Module can be used in two modes of operation: Command Mode and Data Mode. It can also be operated as a master or slave configuration. HC-05 is a Bluetooth SPP (Serial Port Protocol) module designed for wireless communication. This allows the devices to communicate wirelessly with each other.

HC-05 connects microcontrollers (like Arduino) to other Bluetooth enabled devices. The HC-05 is very easy to use Bluetooth to serial converter.

It uses frequency-hopping spread spectrum (FHSS) radio technology to send data over the air.ĭownload the full datasheet from this link: HC-05 Datasheet HC-05 Bluetooth module follows the IEEE 802.15.1 standardized protocol, through which one can build a wireless Personal Area Network (PAN).Working temperature: -20 ~ +75Centigrade.Security: Authentication and encryption.Speed: Asynchronous communication: 2.1Mbps (Max) / 160 kbps, Synchronous communication: 1Mbps/1Mbps.Modulation: GFSK (Gaussian Frequency Shift Keying).Bluetooth protocol: Bluetooth Specification v2.0+EDR (Enhanced Data Rate).HC-05 Specifications HC-05 Specifications It is used to check if the module is connected or not. The HC-05 Bluetooth module receives the data from this pin and then transmits it wirelessly. This pin transmits Serial data (wireless signals received by the Bluetooth module are converted by module and transmitted out serially on this pin)Ĭonnect this pin to the TXD pin of the Microcontroller. Give 5V / 3.3 V to this Pin.Ĭonnect this pin with the RXD pin of the Microcontroller. In HC-05, the default baud speed in command mode is 38400bps and 9600 in data mode. The Key/EN pin should be high to operate Bluetooth in command mode. By default, this pin operates in data mode. This pin is used to bring the Bluetooth module in AT commands mode. HC-05 pinout and specifications are given below. HC-05 Bluetooth module is a Bluetooth to serial converter that connects microcontrollers (like Arduino) to other Bluetooth enabled devices.
