GPSD difficulties xubuntu

injijagwalaafq · 10-21-2019, 05:52 PM

I am trying to setup gps on a ubuntu based cap pc system. I have gpsd and gpsd -clients installed via apt. I have been trying to follow these instructions. My GPS reciver is a usb device.

lsusb gives the following

Code:

Bus 001 Device 006: ID 058f:6254 Alcor Micro Corp. USB Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 007: ID 1546:01a7 U-Blox AG
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 003: ID 0557:2213 ATEN International Co., Ltd CS682 2-Port USB 2.0 DVI KVM Switch
Bus 003 Device 002: ID 0557:8021 ATEN International Co., Ltd CS1764A [CubiQ DVI KVMP Switch]
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 003: ID 0cf3:3004 Atheros Communications, Inc. AR3012 Bluetooth 4.0
Bus 002 Device 002: ID 0cf3:3004 Atheros Communications, Inc. AR3012 Bluetooth 4.0
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

This tells me that my reciver is USB007.
Attempting to run

Code:

stty -F /dev/USB007 ispeed 4800 && cat </dev/USB007

gives the following:No such file or directory.

Running gpsd -D 5 -N -n /dev/ttyUSB007 the system says the the daemon is already running. after stopping the daemon and re running the above command it seems to execute normally. However, I am unable to run the next test command, which is telnet into the device.

So I am a couple of kinds of lost and frustrated. If there is a homer Simpson (mega idiot) proof method I am listening.

Thanks

Knowing the model number might help but look at the output of the dmesg command after you plug in the device. I would guess if the receiver is automatically recognized the device ID is /dev/ttyACM0.

That seems to have felt with that issue. Running gpsd -D 5 -N -n /dev/ttyACM0 made the console dump endless gobbly gook. I guessing that is raw gps data. Progress. I hit control c and then ran chips. It seemed to attach the device. It did not report getting any signal. At least not that I could tell. No surprise considering that i am inside on the ground floor.

Am i going to have to run that command every time the system starts up?

Thanks

Whether the globally goob is meaningfully depends on what dialect the receiver outputs. If it was binary or text and if gpsd recognized the data. If moving the receiver to a window does not result in a signal indicator the additional troubleshooting is required.

I assume you are running a recent Ubuntu version and therefore using systemd. You casystems on how to write system script to start gpsd at boot.
