Hi there, I have my hc-05 wired up to my arduino using just the four pins, gnd, vcc, rx, and tx. I've tried both my hc-05's now, and they both have the same issue on my windows 10 computer. On my mac, I was able to stay connected. Why might the hc-05's disconnect only after a few seconds?

HC-05 Disconnecting After 2 seconds

You mentioned before using the 3V.
I think it's inadequate.
Can you power from "5V" and GND (disconnect rx, tx and en for now)?
Does it stay 'connected' then?
