Re: [gpsd-dev] OS X dropped. How I think about our platform priorities

Your characterization of what's going on seems off; see my recent mail.

And I don't think there's any justification for claiming that this is
necessarily a mac bug, even though I think it's 90% likely.

I haven't received my USB GPS from Gary yet (@ Gary - where's my GPS? ;^) ), so I did some more testing with the bluetooth receiver...

I did a clean install of Ubuntu Desktop LTS on a PC that has Intel WiFI & Bluetooth built-in. Ubuntu was patched to current. I cloned and built the current gpsd. After working through the Linux bluetooth BS, my results on the Linux PC match ** EXACTLY ** my results on the Mac. My issues are NOT related to running on Mac OS X.

My issue may be related to the documented (in gpsd docs) issue with some bluetooth GPS receivers. To get my bluetooth GPS to work at all, I seem to have to remove power form the GPS (no battery in the GPS), wait (several minutes), and possibly power down the Ubuntu system - not reboot (this step is not confirmed to be required, as I may have not been waiting long enough after the GPS power removal).

@ Eric - The Ubuntu system is available to you. The hostname is "miner1". The credentials I sent you earlier will get you on that system. I will leave the GPS and system in a state that **should** work on the first attempt.

Below is a log from the session of both working & then failing. In the log below, when gpsd was working, the client connecting was 'cgps'. cgps never receives any data and just exists.
