HC-06 Bluetooth Slave Serial (UART) Module

The HC-06 is a slave Bluetooth 2.0+EDR serial (UART) pass-through module. It can easily pair with a master Bluetooth device but cannot pair with another slave device. It can be connected to the serial pins on your Arduino or other dev board and serve as a wireless serial link, all without having to do anything except connect power, ground, Tx, and Rx. Once powered, the module automatically starts broadcasting its ID waiting for a master Bluetooth device to pair with it. The module has an on-board voltage regulator which allows you to power the module with supply voltages of 3.6V to 6V. With a logic level of 3.3V you can directly connect this module to a Raspberry Pi but we recommend using a logic level converter when connecting it to 5V logic devices such as most Arduino boards. Specifications Supply Voltage: 3.6V to 6V Chipset: CSR BC417 Bluetooth Version: V2.0 + EDR Default Device ID: Addicore HC-06 Default Passcode: 1234 Default Baud Rate: 9600 Board Dimensions: Length (not including pins): 37mm (1.457") Width: 16.96mm (0.668") Resources HC-06 Module Datasheet Guide to using the HC-06 (By Erich Styger) Windows Bluetooth Terminal App (If you have a Bluetooth dongle, or your computer has integrated Bluetooth, then this app works for communicating with the HC-06 module over Bluetooth.) Changing the ID, Passcode, or Baud Rate You can use AT commands, without any new-line or return characters, to change the following settings on the HC-06: Device ID: Send “AT+NAMExxxx” where xxxx is the new name Example: "AT+NAMEMyDevice" will change the name to MyDevice Passcode: Send “AT+PIN####” replace #### with desired four digit pin Example: "AT+PIN9876" will change the passcode to 9876 Baud Rate: Send “AT+BAUD#” replace # with the associated baud code found in the Baud Rate Code List below Example: "AT+BAUD8" will change the baud rate to 115200   Baud Rate Code List Baud Code - Baud Rate 1 - 1200 2 - 2400 3 - 4800 4 - 9600 (Default) 5 - 19200 6 - 38400 7 - 57600 8 - 115200 9 - 230400 A - 460800 B - 921600 C - 1382400
