#60 Fedora 14 cannot connect

[Serge Droz]

Hello
I've recently upgraded to Fedora 14 x86_x64. No version of bt747 seems to be able to connect anymore.
There is an issue with the the lockfile under Fedora 14, but the latest rxtx RPM from fedora 14 is supposed to fix this.
In fact, I can connect, (the button changes to disconnect). But the GPS Device Data part takes ages to update, and only partial updates. Download does not succeed. I have no problem on my mac.
I've tried different version to no avail.

Any ideas?

Serge

Hi Mario,

thanks foor the answer. I hadn't seen this one. And it's not the problem. But it made me poke around a little more in the udev files, which brought me to the right solution.
Fedora 14 installs gpsd. After killing this process things worked as before. It seems, not to surprisingly, that the two applications cannot coexist .

So for Fedora 14 one must:
1) Install the redhat supplied rxtx RPM (currently in the updates-testing repository)
2) Comment out the rule in /etc/udev/rules.d/99-gpsd.rules corresponding to your device, so gpsd is not started

Thanks a lot for the quick response
Most appreciated.

Serge

Hi

Thanks for the update. I should add 'gpsd' to a faq somewhere.

I looked if it is possible to interface with gpsd - it might be but is not so straightforward. It seems to require building a native library using 'libgpsd' (http://gpsd.berlios.de/libgpsd.html ).
The high level interface does not seem to allow talking and receiving from the device as is required.
