rfcomm_sppd -- RFCOMM Serial Port Profile daemon
rfcomm_sppd [-d device] [-m mode] [-p psm] [-s service] [-t tty] {-a address | [-c channel]}
The rfcomm_sppd utility is a Serial Port Profile daemon, providing serial access over an RFCOMM connection to a remote device. rfcomm_sppd can work in client or server mode. In client mode, rfcomm_sppd initiates an RFCOMM connection to the service at the remote address. In server mode, rfcomm_sppd registers the service with the local SDP server and listens on the specified RFCOMM channel for an incoming con- nection, or the first unused channel if none was given. The options are as follows: -a address Client mode. Specify the address of the remote RFCOMM device. The address can be specified as BD_ADDR or name. If given as a name, then the rfcomm_sppd utility will attempt to resolve the name via bt_gethostbyname(3). -c channel In server mode, specify the RFCOMM channel number to listen on. rfcomm_sppd will register the service with the local sdpd(8) daemon. Note that registering services with sdpd(8) is a privileged operation. -d device Use the local device with the specified address. The device can be specified by BD_ADDR or device name. See btconfig(8) for a list of available devices. If no device is specified, the connection will be set up on a system determined device. -m mode Set connection link mode. Supported modes are: auth require devices be paired. encrypt auth, plus enable encryption. secure encryption, plus change of link key. -p psm Specify the "Protocol/Service Multiplexer" value to be used for the RFCOMM protocol. In client mode where Service Dis- covery is being used, this value will be ignored. -s service Name of service class to connect to or register. If no service is given, the default "Serial Port" service class will be used. Known service classes are: DUN Dialup Networking LAN LAN access using PPP SP Serial Port In client mode, the service class may be given as a channel number, for instances where the remote device does not pro- vide Service Discovery. -t tty Slave pseudo tty name. If this option is given, rfcomm_sppd will detach from the controlling process after the Bluetooth connection is made, and operate over the named pty(4) pair. Otherwise, stdin/stdout will be used.
/dev/pty[p-sP-S][0-9a-v] master pseudo terminals /dev/tty[p-sP-S][0-9a-v] slave pseudo terminals
The rfcomm_sppd utility exits 0 on success, and >0 if an error occurs.
rfcomm_sppd -a 00:01:02:03:04:05 -s 1 -t /dev/ttyp1 Will open an RFCOMM connection to the server at 00:01:02:03:04:05 on channel 1. Once the connection has been established, rfcomm_sppd will detach and /dev/ttyp1 can be used to communicate with the remote serial port on the server, e.g. with the use of cu -l /dev/ttyp1 In order to use rfcomm_sppd to automatically create a secured link for pppd(8), use pty "rfcomm_sppd -a 00:01:02:03:04:05 -s DUN -m secure" in your pppd(8) configuration file.
