I know that I need to pull pin #34 high on the HC-05 "chip" (AKA PIO11) while powering ON the chip in order to put it into AT mode. Can I leave that pin high while programming, or does it need to go back to ground immediately after it is in AT mode in order to program?
From the datasheet I interpret it as that I can leave it high while programming the chip, then put it back to low when I re-power the module for normal use.
Looking for confirmation. Thank you!
