Wireless Bluetooth module is intended to be used in conjunction with our Bluetooth slave module (ARDU0004). When the module is correctly connected to a 3.6 to 6V supply and a slave is within range, the master module will automatically pair with the slave module. This means a serial to serial connection over a wireless Bluetooth link can be made without requiring any software interaction.
Please note that if you require a module for connection to other Bluetooth devices such are a PC, smart phone, etc., please purchase our slave module instead (ARDU00004).
