I'm hoping that someone can help me to get my HC-06 up and running. It appears the problem is that the HC-06 remains disconnected, however It is paired. The led on the HC-06 keeps flashing. The voltage to the RXD on the Hc-06 is .96 volts. The TX pin from the Arduino is connected to the 4.7 k resistor divider, the voltage at this resistor is 1.4 volts. When the jumper from the TX is the voltage measures 4.8 volts. I'm not sure what's bringing the voltage to 0.91 volts at the 4.7K/10K divider. Is 3.3 volts the minimal voltage that is required at the RX of the HC-06?

Just use a 1k and a 2k like everybody else does. If it is paired, that just means that the power supply to the HC-06 is OK.
