I found I had to charge my Sprint for several hours first before it would successfully be detected by a Windows or Android device's Bluetooth pairing function. Normally, I think, the device goes from LED off (powered off) to blink to steady red when turned on; if it detects a pairing attempt, it blinks blue. Steady blue indicates successful pairing.
