Learning HC-05 but cannot get past basics

@Nick_Pyner

OK, it was worth a try. And do I understand correctly that you have never had a problem with the data on the serial monitor?

Yes, that's correct

@cattledog

Is it a pattern of 2 rapid flashes (on, off, on, off, takes ≈ 1 second) then a pause (off) of several seconds?

Yes, that's correct

@groundFungus

Would you be willing to change the HC05 back to 9600 baud and try with software serial.

Yes, will do it momentarily.
