Re: [Bluez-users] rfcomm question 3

Hi Michael,

> a)Just include "rctest.c" by creating "rctest.h" in bluez-utils-2.14/test directory, and put the function prototypes related to listening on a RFCOMM channel and include the header files bluetooth.h and rfcomm.h in my main program

Are you kidding ?

> b)put the functions related to listening on a RFCOMM channel in my main program, and include the header files  bluetooth.h and rfcomm.h in the beginning.

Seems much better than the first idea. basically only do_listen and recv_mode
should be important in your case.

> So, which approach is more appropriate?

The second one.

> And for each approach, what variables need I to declare in the beginning of my main program?

Are you kidding ? (once more) .. this is not a bluetooth/socket API question
anymore but just C programming you are asking about. Are we here for that ?

> 2.My wish is to let the program to accept all mobiles that wish to connect to PC. Then how can I write the syntax so that if one mobile wish to connect to PC, the PC can accept it?

Take a look at the function do_listen ... the bind call.

        loc_addr.rc_family = AF_BLUETOOTH;
        loc_addr.rc_bdaddr = BDADDR_ANY;
        loc_addr.rc_channel = channel;
        if( bind(s, (struct sockaddr *) &loc_addr, sizeof(loc_addr)) < 0 ) {

should let you get connection from any device ....

> And how can I do to count and check the number of mobile terminals connecting with PC?
> 3.What online reference is good for me to get familiar with the matter that I asked in the previous two questions?

Some googleing with keyword like "socket programming" should be a good start.

Regards,

Alain
