The easiest Arduino Uno Bluetooth shield for your Arduino Uno project is SeeedStudio Bluetooth Shield. Simply by plugging the Bluetooth Shield on your Arduino Uno and it has been ready for use. SeeedStudio bluetooth shield work using serial communication. You can choose two pins from Adruino Uno (from pin D0 to D7) to be used as Software Serial Port – Transmite Data (TX) and Receive Data (RX). You can choose RX and TX pins by sliding ‘jumper pin’ on the port that you want (D0 to D7).

You can still use all the Arduino pin bluetooth although this shield cover Arduino Uno board. This Bluetooth shield provides 2 grove connectors (digital and analog) for you to install the grove module.
|PIO1||Status instruction port of Bluetooth module can be read by Arduino A1 port: low-disconnected, high-connected.|
|BT_RX||UART Data input of Bluetooth module.|
|BT_TX||UART Data output Bluetooth module.|
|Two Grove connectors||One is Digital (D8 and D9), the other is I2C/Analog (A4 and A5).|
You can set this shield bluetooth become a master or slave. For a tutorial and sample programs (source code program) you can also read on this blog.
You can connect this bluetooth shield with the other one (2 different bluetooth shield). You can also connect a Bluetooth shield with a laptop or computer. You can also connect a Bluetooth shield with the smartphone.
