Hi all,
I would like your opinion on something. Im currently doing a school project and it requires me to use a Bluetooth headset as the receiver for my tone. I am then to perform signal converison. However, the Bluetooth headset would not function when it's charging. There are 3 wires from my Bluetooth headset. 2 outputs and one ground. Since it wont be able to function when it's charging, im having difficulty grounding it. When the output is observe on the oscilloscope, it needs to be grounded to form a close loop else the output cant be observe. When the headset is connected to my circuit, the ground from the headset needs to be separated from my power source ground. To observe the output from the osilloscope, the headset ground needs to be connected to the oscilloscope. Both are not connected to the power source ground. Does it mean im nt grounding my headset at all?![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
