Supports the AT command to modify the baud rate, device name, passkey, master/slave, etc. The Bluetooth serial module I bought has the following specs: - Default COM setting: 9600, N, 8,1 - Default Password/pairing code: 1234. I did not consider these features a necessity but some of you might want to pay more and get an enhanced version of this transceiver with all of these features. ![]() Then there's the absence of power LED as well as no TX/RX LEDs. The only downside of this cheap Bluetooth transceiver is the absence of headers which means you have to solder at least 4 wires. The distance for this transceiver is about 30 feet or so but it really depends on many other variables. The Arduino to PC connection can be useful in applications where the Arduino reads sensors then pass their values via serial Bluetooth to a PC for processing. The PC to Arduino Bluetooth serial connection can be useful in many applications such as controlling servos, motors, and writing to LCDs. This Bluetooth transceiver basically acts as a generic serial COM port. I strongly recommend buying the module with the breakout board. The version I have used in this project does not have a breakout board so it's little cheaper but more difficult to solder. INTRODUCTION In the guide, I will explain how I managed to send data back and forth between a PC and Arduino via a cheap Bluetooth HC-05 transceiver, which can be found for less than $10 on ebay with the breakout board.
