Hi all! i try the new version of Navigatrix (great work!) but when i connect my GPS (qstarz 818x-bluetooth) i see on the bluetooth-window is connect to serial port /dev/rfcomm0 and Qstarz GPS unknown 00:1c:88:12:3b:a1. On the bottom of the window the amount of data is changing and the two little icons are blinking... can you maybe give any help with this problem ( I'm absolute beginner!!! :( )

I'm not sure why it not picking up the gps. Bluetooth is a mystery to me.

This is a quick fix.

Open a terminal; (<ctrl><alt><t> at the same time...or Ray> Accessories> Terminal Emulator) and enter:
Code:
sudo dpkg-reconfigure gpsg
The window will open the gpsd reconfiguration script.

The first two screens are unchanged, hitting <Enter> advances you to the next screen.

The third screen is instruction for the gpsd where to look for a gps. Blank means look at everything. You could point to directly to your gps. 1) enter the location; 2)<tab> to change to <ok> and then <Enter> to activate the change.

<Enter> to pass through the rest of the options until the script closes.

Then follow it up with:
Code:
sudo service gpsd restart


Give that a go.

If it has been a while since the gps was last used it can take up to 15 minutes from a cold-dead start.

That will give me a chance to think of the next step.

another little problem is that i can't see the whole window from xgps on my small screen (acer aspire one AO 531h, with only 11 inch) i can only reduce or open it, but not resize, so i don't see all data on the bottom... is not very important.

It helps to know the gps tested and works out of the box with gpsd.

Inn Navigatrix the default is with the -b flag.

I've got a solution for your screen size...as soon as I find where I archived it.

It has already been done.

There are three flags set by default.
Quote:
-b

Broken-device-safety mode, otherwise known as read-only mode. A few bluetooth and USB receivers lock up or become totally inaccessible when probed or reconfigured; see the hardware compatibility list on the GPSD project website for details. This switch prevents gpsd from writing to a receiver. This means that gpsd cannot configure the receiver for optimal performance, but it also means that gpsd cannot break the receiver. A better solution would be for Bluetooth to not be so fragile. A platform independent method to identify serial-over-Bluetooth devices would also be nice.
-G

This flag causes gpsd to listen on all addresses (INADDR_ANY) rather than just the loop back (INADDR_LOOPBACK) address. For the sake of privacy and security, TPV information is now private to the local machine until the user makes an effort to expose this to the world.

-n

Don't wait for a client to connect before polling whatever GPS is associated with it. Some RS232 GPSes wait in a standby mode (drawing less power) when the host machine is not asserting DTR, and some cellphone and handheld embedded GPSes have similar behaviors. Accordingly, waiting for a watch request to open the device may save battery power. (This capability is rare in consumer-grade devices).

yeah, sorry...that's nothing. Those are just warnings that say an icon for the user interface is not where it should be. It really doesn't matter. But like a nagging conscience, it can't 'undo' the past, but it never forgets.

When you use the Menu to start the text editor it doesn't matter; you don't see those errors...one of the dirty little secrets of the GUI world.

There are 'warnings', 'errors', possibly on several layers, some even 'good'...and then there are 'fatal errors'; which tend to be 'not-good'.

If you modify the connections in OpenCPN you could be inviting more trouble. Hang in there, a solution can be found.

Hello Moi, i have try now to reconfigure GPSD service, on the window socket path i see : /var/run/gpsd.sock is this path right?

Now on the connexion window OPENCPN i see: red localhost2947 0 GPSD no

GoneTropo had a fix for Bluetooth gps and those wanting to go places.
Quote:
using the spare nx usb stick I connected the gps with BT Manager and then in terminal
nx@nx:~$ rfcomm
rfcomm0: 00:23:06:D7:8D:19 -> 00:1C:88:11:0C:02 channel 1 connected [reuse-dlc tty-attached]
Then removed the gps device in BT manager. Then in terminal
nx@nx:~$ sudo medit /etc/bluetooth/rfcomm.conf (as Moe said above)

# RFCOMM configuration file.
#
# # Automatically bind the device at startup
bind yes;
#
# # Bluetooth address of the device
device 00:1C:88:11:0C:02;
#
# # RFCOMM channel for the connection
channel 1;
#
# # Description of the connection
# comment "Example Bluetooth device";
}

Then in terminal
nx@nx:~$ hcitool scan
Scanning ...
00:1C:88:11:0C:02 iBT-GPS
nx@nx:~$ rfcomm
nx@nx:~$
At this point I rebooted and the gps was auto connected to rfcomm0 in BT manager
nx@nx:~$ rfcomm
rfcomm0: 00:1C:88:11:0C:02 channel 1 connected [tty-attached]
Xgps was happy and all is right with the world :D

Hi Moe!
I have do it as follow:
Code:
#
# RFCOMM configuration file.
#

 rfcomm0 {
#   # Automatically bind the device at startup
 bind yes;
#
#   # Bluetooth address of the device
 device 00:1C:88:12:3B:A1;
#
#   # RFCOMM channel for the connection
 channel   1;
#
#   # Description of the connection
#   comment "Example Bluetooth device";
 }


Than on terminal:
Code:
nx@nx:~$ hcitool scan
Scanning ...
   00:1C:88:12:3B:A1   Qstarz GPS


After reboot:
Code:
nx@nx:~$ rfcomm
rfcomm0: 00:1C:88:12:3B:A1 channel 1 connected [tty-attached]


But is the same problem, have not data on Xgps or OpenCPN...

:(

It's working now! i have make a copy on another USB stick, and do the script modifications (like above) and Open CPN receive the position!!
Many times when i change the options, the connexion will interrupt (??) and i have to closed and now opening CPN.
Another little problem is that i have loaded KAP Charts (made with GE2kap) but i can't see it, I see only black squares at this place
