Hi,
I am looking for BT module or IC which can be configurable. I got couple of HC-05 module, which can't be configuable. (AT Commands are not working for me).
I got one more option as CC2640, from TI.
Which BT module will be configurable to talk with each other.

yeah, you are right. But i brought the module which can not be configurable. PIN no-34 isn't connected to any pin which is used to enable and disable the AT commands.
Did you tried this module?
Because i tried and many ppl also. if you google it then you will get to know, what i meant to say.

Are you sure that there is no connection to pin 34 on the board ?

This is a picture of one of my Bluetooth modules.

Pin 34 is the bottom connection on the left hand side of the board and you can see the first part of the track going to what loohs like an SMD capacitor. Does your board look the same ?
I have never had a problem with HC-5 modules. I did have trouble with the HC-6 modules until I found out that
all the characters in the AT command have to be sent quicky. (Faster than you can type.) I got round this by using the serial tool on the Arduino IDE. Also typing the command into notepad then doing a copy and paste to a terminal emulator program worked.
