Hi,
I bought the bluetooth module HC-05 along with its associated circuitry. I didn't connect the UART pins. I turned it in communication mode and the name of the device was seen in the mobile when I searched and tried to pair. I entered the passcode, it accespted and said pairing succesful in the mobile, but after two seconds, the pairing is lost and in the module, the LED for showing the succesful pairing is not turned on at all.
Is it because I haven't connected the UART pins? or may there be some fault in the board?
Can somebody kindly help me out here???
