HC-05

Help: Weird HC-05 behavior

Hi. I'm having problems with the HC-05 and I hope someone can help. I've wired it up to an FTDI USB<->Serial connected to my PC just to test it out.

1. If I send it an AT command, it seems to enter an infinite loop where it sends OK back. If I power off & on, send it AT+VERSION, it enters an infinite loop sending the version info and OK. Basically, any AT command gets infinite responses.

I am at my wits end! Ive spent the last three or so hours trying to get this to work with no avail.

Hi,
