Is it possible to communicate wirelessly, directly with a USB adapter on my computer to a UNO with a HC-05 Bluetooth module? I am having problems doing so and realized (maybe) that these modules are meant to be used on the UNO but to talk with other HC-05s or other Bluetooth devices and not the host computer (wirelessly). Are they always used on the Arduino but tethered to the IDE with a USB cable?
I’d like to communicate to the UNO wirelessly (the UNO will have its own power supply). Do I need to accomplish this using another UNO tethered and powered by a USB cable (slave/master)? On-line examples don’t explain this.
