The folder doesn’t = contain any .c file except Makefile, Makefile.am and Makefile.in. ‘manager.c’ is present only in ‘bluez-utils-3.9/daemon’ folder, but = there is no ‘rfcomm_connect()’ implementation. Probably we are using = different utils version.

Thanks again for your time.

You probably made the socket's fd non-blocking. Either make it blocking,

or setup a watcher on the fd to wait for the link to be = created.

 

See rfcomm_connect() in = bluez-utils/serial/manager.c
