Re: [gpsd-users] Earthmate and the Zodiac Driver

[Scott Nolde]

Did the Earthmates require you send back EARTHA prior to getting the binary data?  If so I'm not seeing it sent back.

Here's some -D6 output since I've not yet finished the new world stuff:

so your "test load" file is a pipe which has at the other end a perl
script. But I'm getting ahead of myself.

I doubt it. Sadly my Earthmate is dead. It could probably be
recovered, but again, I'm ahead of myself.

gpsd:PROG: switch_driver(Generic NMEA) called..

so when you get "selecting Delorme EarthMate", the loss would seem to
be immediate.

static void earthmate_event_hook(struct gps_device_t *session, event_t event)
contains:
   if (event == event_identified) {
       (void)gpsd_write(session, "EARTHA\r\n", 8);
       (void)usleep(10000);
       (void)gpsd_switch_driver(session, "Zodiac Binary");
   }

which would tell you something interesting:
   gpsd_report(LOG_PROG, "switch_driver(%s) called...\n", type_name);

But we never see a switch to Zodiac.

So you don't need him. You don't even need a perl script. Your test
input is a file containing a bunch of
EARTHA
strings. Until you see "selecting Zodiac Binary", he's not going to be
happy regardless.


Given in order to get there you would have had to have seen an
accepted packet first:
       gpsd_report(LOG_RAW + 3, "Accepted packet on %s.\n",
                   session->gpsdata.dev.path);
which is gpsd_poll which is at the start of gpsd's event loop, but the

gpsd:DATA: packet from /dev/cuad0 with {ONLINE|DEVICEID|PACKET|DRIVER}

call is further down in that loop, something between that and the
completion of that loop is the presumably the problem.
