The voltage used by bluetooth module is between 2.7v-4.2v, so its output could not get 9v.
The module hasn’t DTR port, it use Tx and Rx to send or receive data from other bluetooth.
The CTS and RTS port is controlled by the module itself as the indication for the user, but they
could not controlled by user directly.
If you really want to use the bluetooth to control your circuit, probably you need to add a simple MCU.
