Hi, I am looking to turn on multiple Bluetooth modules such as the HC-05 and HC-06 just so the can be discovered by my phone when scanning for Bluetooth devices. Can connect the power supply to the multiple Bluetooth devices or must I enable the HC-05/HC-06 devices with an arduino.
I plan to change the Bluetooth name of each device individually prior to turning them all on.

For what purpose? If the bluetooth device is connected to the Arduino, there must be a reason. Connecting multiple devices, and randomly turning some on, or off, doesn't make sense.

I can't see the point of this, but yes, Arduino's sole purpose is to provide power, and is otherwise uninvolved. Check the data sheets, I guess it can power three or four at the same time.

I am working on a Bluetooth related phone app that will interact with arduino based bluetooth hardware.
Step 1: of the testing/ development is for the phone to be able to scan and detect all available Bluetooth devices around it. I plan to use HC-05/HC-06. At the moment i just want to be able to pick up the HC-06 during a phone scan. Hence my question do I need an arduino now to activate the HC-05 now so it discovered by the phone or does just powering up the HC-05 allow it to be identified by the phone.
Step two; will be selecting one of the several bluetooth devices discovered by the and receive data such as tempeture from it, this I know will need an arduino to process and send the data to the phone
do I need an arduino now to activate the HC-05 now so it discovered by the phone or does just powering up the HC-05 allow it to be identified by the phone.
That there is something that cares about the output of the bluetooth device is irrelevant. It is the device itself that, when powered, handles the pairing and discoverability.
The Arduino would be doing nothing, so it is not needed.
