NAME

rfcomm_sppd -- RFCOMM Serial Port Profile daemon

SYNOPSIS

rfcomm_sppd [-d device] [-m mode] [-s service] [-t tty] {-a address | -c channel}

DESCRIPTION

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. 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 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. -s service This is the service class that will be searched for on the remote device. 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.

FILES

/dev/pty[p-sP-S][0-9a-v] master pseudo terminals /dev/tty[p-sP-S][0-9a-v] slave pseudo terminals

EXIT STATUS

The rfcomm_sppd utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

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.
