Hello, I am writing an application and I would like to make it communicate with a T68i cellphone via a bluetooth connection. Yeah, I'm new to bluetooth development and protocols. The device is already paired with the Mac, so there is a serial port available for communicating and I could use the usual posix routines to open the port and do serial i/o. However, I would like to be able to communicate with it without preventing other applications from being able to use that serial port. As far as I know, the Address Book application does that. How is this achieved? Or does the Address Book application only open the serial port in a read-only mode with allows other processes to access it? But Address Book does send AT commands to the phone, so it can't be read-only... Any hints? Thank you very much!
