Dear Friends: I have just bought a Bluetooth device HC-05 from J-Deal. When I'm trying to program it with AT commands, I found out that the connector doesn't has any KEY pin or PIN34 pin. It only has RXD, TXD, GND, VCC, Status and EN pins. None of them has continuity to PIN34 measured with a multimeter. Any of you can tell me where to connect the HIGH to PIN34 to program it? Thanks in advance for your quick reply. Eduardo
Go back and check again. While you are at it, check to see if there is a button near EN and, if so, press it. The modules comes on different breakout boards these days. Yours might be labelled ZS-040. Check the Martyn Currey website, he seems to cover this best. STATUS is just another LED as an option to that on board.
