Verify /dev/rfcomm0 is rwx using ls. Also try "cat /dev/rfcomm0" and/or "wc /dev/rfcomm0" to see if they give errors. You might also want to try the above with "strace" preceeding the command just to see the open, and/or with "sudo"
I normally have to start "rfcomm connect 0 <btaddr>" before it goes live - there is a way to give the address in a config file and maybe do it automatically but I've always done it from the command line. This program must automatically create /dev/rfcomm0. Simply pairing the device and doing mknod will not associate the network pipe with the device node. -- Cannot open /dev/rfcomm0: Permission denied after upgrade to 9.04 https://bugs.launchpad.net/bugs/374782 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
