Bluetooth Module HC05 in Pakistan

(1 customer review)

This is a great little board containing an EGBT-045MS Bluetooth Module, voltage regulation, logic level conversion and LED activity indicators.

These modems work as a serial (RX/TX) connection, and are a great wireless replacement for serial cables.

The HT Bluetooth Module has the same pin out as the FTDI Basic 5V, FTDI Basic 3.3V, Bluetooth Mate Silver and can plug directly into Arduino Pro, Pro Mini 5V, Pro Mini 3.3V boards.

The EGBT-046S Bluetooth Module is a generic Bluetooth device loaded with SPP firmware for UART wireless cable replacement functions. This version of the board can act as a MASTER or SLAVE device.

Command Mode / Data Mode
The module has two modes of operation, Command Mode where we can send AT commands to it and Data Mode where it transmits and receives data to another bluetooth module.

The default mode is DATA Mode.

There are two ways to get into Command Mode

1. Connect the CMD pin high before applying power to the module.

This will put the module into command mode at 38400 baud. This is useful when you dont know the baud rate the module is set to.

2. Apply power to the module then pull the CMD pin high.

This will enter command mode at the currently configured baud rate. This is useful if you want to send AT commands from say a microcontroller as the CMD pin can be controlled from one of the microcontroller pins.

Commands are sent to the module in UPPERCASE and are terminated with a CR/LF pair

Command Mode Commands
Apart from the commands described below for configuring master/slave operation, the following useful commands are available.
