HC-05 Bluetooth Module Serial Monitor Problem

  1. Normal practice is to connect Tx to Rx and Rx to Tx. Transmitters transmit to receivers, and receivers listen to transmitters.

  2. None of the pictures you post appear to have anything to do with what you are actually doing, and they are all meaningless.

  3. You are using the hardware serial pins 0,1 for software serial. This is not a good idea. You won't do any actual damage, but you won't get anywhere either. If you want to use software serial, use different pins like 5,6 - pretty well anything other than 0,1

Your intentions are unclear, but you might find the following background notes useful
