Net::GPSD3::Return::DEVICE - Net::GPSD3 Return DEVICE Object SYNOPSIS
DESCRIPTION
Provides a Perl object interface to the DEVICE object returned by the GPSD daemon. METHODS
class Returns the object class string Returns the JSON string parent Return the parent Net::GPSD3 object device Name the device for which the control bits are being reported, or for which they are to be applied. This attribute may be omitted only when there is exactly one subscribed channel. driver GPSD's name for the device driver type. Won't be reported before gpsd has seen identifiable packets from the device. subtype Whatever version information the device returned. path native 0 means NMEA mode and 1 means alternate mode (binary if it has one, for SiRF and Evermore chipsets in particular). Attempting to set this mode on a non-GPS device will yield an error. activated Time the device was activated, or 0 if it is being closed. Note: I expect this to change to either a boolean or a timestamp in the 3.5 protocol. cycle Device cycle time in seconds. mincycle Device minimum cycle time in seconds. Reported from ?CONFIGDEV when (and only when) the rate is switchable. It is read-only and not settable. flags Bit vector of property flags. Currently defined flags are: describe packet types seen so far (GPS, RTCM2, RTCM3, AIS). Won't be reported if empty, e.g. before gpsd has seen identifiable packets from the device. bps Device speed in bits per second. parity N, O or E for no parity, odd, or even. stopbits Stop bits (1 or 2).

gpspipe - tool to connect to gpsd and retrieve sentences SYNOPSIS
gpspipe [-h] [-d] [-l] [-o filename] [-n count] [-r] [-R] [-s serial-device] [-t] [-T timestamp-format] [-p] [-w] [-v] [-D debug-level] [server [:port [:device]]] DESCRIPTION
gpspipe is a tool to connect to gpsd and output the received sentences to stdout. This makes the program useful as a pipe from gpsd to another program or file. gpspipe does not require root privileges, and can be run concurrently with other tools connecting to the local gpsd without causing problems. The output will consist of one or both of the raw NMEA or native gpsd sentences. Each line can be optionally time stamped. There is also an option to exit gracefully after a given count of packets. Optionally a server, TCP/IP port number and remote device can be given. If omitted, gpspipe connects to localhost on the default port (2947) and watches all devices opened by gpsd. gpspipe may be run as a daemon, but requires the -o flag for writing the output to a file. OPTIONS
-h makes gpspipe print a usage message and exit. -d causes gpspipe to run as a daemon. -l causes gpspipe to sleep for ten seconds before attempting to connect to gpsd. This is very useful when running as a daemon, giving gpsd time to start before attempting a connection. -r causes raw NMEA sentences to be output. -R causes super-raw (gps binary) data to be output. This overrides NMEA and gpsd output modes. -s option causes the collected data to be written to the specified serial device with settings 4800 8N1. Thus gpspipe can be used with -s and -r options to emulate a serial port hardwired to a GPS that gpsd is managing. -o option causes the collected data to be written to the specified file. Use of this option is mandatory if gpspipe is run as a daemon. -w causes native gpsdsentences to be output. -t adds a timestamp to each sentence output. -T sets the format of the timestamp. See strftime(3) for the available placeholders. Setting this option implies -t. -p enables dumping of profiling information in JSON. -n [count] causes [count] sentences to be output. gpspipe will then exit gracefully. -v causes gpspipe to show a spinning activity indicator on stderr. This is useful if stdout is redirected into a file or a pipe. By default the spinner is advanced with every messages written; specifying -v more than once will double the number of messages required to rotate the spinner. -V prints the version, then exits. At least one of -R, -r or -w must be specified. EXAMPLE
When gpsd is running gpspipe -r -n 100 will send one hundred raw NMEA sentences to standard output, then exit. SEE ALSO
