| eb500 bluetooth module (Updated With USART Code...Need help) |

hi guys, I'm currently making the bluetooth integration with my robot after finished my sensor problem. I'm using this bluetooth
http://www.a7eng.com/products/bluetooth/productpages/eb500-ser.htm.
Actually I don't have any experience on setting the bluetooth using pic16f877a. But I found a bluetooth driver that I think can be use in my project.
http://www.ccsinfo.com/forum/viewtopic.php?t=31248&highlight=bluetooth.
But I found out that the driver may be used for serial port bluetooth module. Is there any other drivers for this module? I already search at the another forum, but got no result.
Also I just want to know on how to write up a code for the pic to create a connection (handshake) between module and laptop. I heard that we can set it by only adjust the ic settings at the module or do some basic stamp which I don't know what software should I use to program the basic stamp. hopefully someone can give me some idea on how to do the connection between laptop and module.
