HC-05 not working with some apps

Better than nothing, still don't understand why the other did not work. Worked great for me.

  • If I remove the 5V jumper will the motors go even slightly slower?

It should already be removed.
Are you saying that you have it on?

My HC-05 randomly loses connection but this happens rarely. By removing the 5v jumper, will it help the HC-05 in any way?

It should already be removed.

Stick to HC-05 problems only in this topic, now it's getting confusing.
