There are two if conditions used inside the loop function. First condition checks if any command is given to HC05, if yes, then write it to Arduino Serial Monitor. The second condition checks if any ...

This is a n empty sketch with a loop. Connect arduino ground to its reset. This way we can bypass arduino. Connect esp Tx to arduino Tx and eap Rx to arduino Rx. Now in serial monitor you should be ...
