Hc 05 Module Bluetooth. This project is equivalent to the "Hello World" program However, it does not support some of the advanced features of the HC-05, such as the ability to enter AT mode to configure the module.
HC05 Bluetooth Module For Ardunio With TTL Output from www.deltakit.net
Note that the serial lines are connected to PIN 2 and PIN 3 instead of the standard RXD and TXD Pins of the Arduino. The HC-05 Bluetooth Module can be used in two modes of operation: Command Mode and Data Mode
HC05 Bluetooth Module For Ardunio With TTL Output
However, it does not support some of the advanced features of the HC-05, such as the ability to enter AT mode to configure the module. This project is equivalent to the "Hello World" program Conversely, data written to the UART port prompts the HC-05 to construct a Bluetooth packet.
. Comparing it to the HC-06 module, which can only be set as a Slave, the HC-05 can be set as Master as well which enables making a communication between two separate Arduino Boards. Slave Mode: In this mode, the module waits for a connection request from a master device, such as a smartphone, laptop, or another Bluetooth-enabled device.
. HC-05 Bluetooth Module is a low-cost, easy-to-operate & small-sized module used for wireless communication in the Bluetooth spectrum.; It supports Serial Port Protocol (SPP), which helps in sending/receiving data to/from a microcontroller (i.e In Command Mode, you can communicate with the Bluetooth module through AT Commands for configuring various settings and parameters of the Module like get the firmware information, changing Baud Rate, changing module name, it can be used.
