SURE Bluetooth GP-GC021 problem?

Hi.
I recently bought an bluetooth device to communicate trought PC with my ATMEGA32 controller.
The module is manufactured by SURE eletronics (GP-GC021) 9600 bps.
I´m using a mini bluetooth dongle in my PC.
I ´m able to connect to the device and change some informations, the problem is that the device disconnects by itself just a few minutes after it´s connected, in the middle of a transmition or not.
I heard something about “DeepSleep” mode, i don´t know what is it and i don´t know if this is the problem, but i think that the device shouldn´t never interrupt the communication by itself after connected.
I just want to disconnect my device when i power it off or disable it in the bluetooth PC manager.
Somebody here har the same problem with this device or any other similar?
Thanks for now!!!

We’re mainly using the Blue Smirf products from SparkFun Electronics on the robots discussed on this list.

We’re using Microchip PICs or the Renesas parts programmed in AtomBasic, so no help there either.

I’d try an ATMEL support list, or one of the more general robotic lists.

I have the same bluetooth adapter.
They are very temperamental.

Right now i’m going nuts trying to get my brand new $20 high quality usb bluetooth dongle to even find the sure uart adapter.

My new usb dongle worked before with the adapter, but i tried searching for the uart adapter with my netbook with no luck, after that, my new usb dongle was no longer able to connect.
So i removed it hoping to re-find and reconnect it, now my usb dongle cant find it at all.

Pain in the butt it is.

I’m using a 3.333v regulator, and a 3.3v <-> 5v TTL converter from sparkfun, was working great until i tried to search for the thing with my netbook.
Now it just cant find it at all.
Damn, when the uart adapters work, they work great, when they don’t work, you’ll pull hair trying to figure it out.
Stupid netbook, no matter what i do, it doesn’t seem to like serial ports.

Hey how did you guys manage to talk to the GP-GC021 in teh first place ???

Schematic diagram would help.

Im trying to talk to a GL-6B which is of identical nature to GP-GC021 and I am having a hard time trying to discover it. All I did was to hook up the power, reset and rx tx to the micro.

here the link for manual, may be helpful.

as for me this one doesn’t look as good BT module for robotics (preffered application due to manual is audio)
try to connect it to PC via uart and make any configuration using hyprterm and AT commands (i’m not sure this one supports this option, but)
AT commands example here (other module but same BT core)
