HC-05 Bluetooth problems...

Using Arduino Networking, Protocols, and Devices

Hi there.

I am having problems with my HC-05 bluetooth module.

If i power it up and connect RX to arduino TX and TX to arduino RX. I can send values and the arduino reads them just fine.

The problem is that I can't get the bluetooth module into command mode so I can set its name and change passcode etc I set the PIO11 (pin number 34) high (to 3.3v) but I cannot then see the virtual bluetooth serial port any more? and it won't open the port?

Is there any way that I could use the arduino to send AT commands to the bluetooth module?

This is the module: http://cgi.ebay.co.uk/Wireless-Bluetooth-Transceiver-Module-RS232-TTL-2-4GHz_W0QQitemZ170610903066QQcategoryZ34165QQcmdZViewItemQQ_trksidZp5197.m7QQ_trkparmsZalgo%3DLVI%26itu%3DUCI%26otn%3D4%26po%3DLVI%26ps%3D63%26clkid%3D8150326821526789705#ht_1494wt_1084

Any help would be really nice.
