[obdgpslogger] obdgpslogger on Mac OS X 10.6.8

[Matthew Hixson]

Hi, I've successfully built obdgpslogger, its modules, and gpsd on Mac OS X 10.6.8. Everything seems to be running except for one message from obdgpslogger and the fact that nothing gets logged to the sqlite database.

obdgpslogger -s /dev/tty.usbserial-0000103D -b 115200 -i temp,rpm,maf,throttlepos -t -d data.db
Opening serial port /dev/tty.usbserial-0000103D, this can take a while
Successfully connected to serial port. Will log obd data
Successfully connected to gpsd. Will log gps data
Couldn't get obd bytes for cmd 00
GPS acquisition complete
gpspos=48.391204,-122.252273,136.480000,0.004000,346.212800

Logging of GPS data continues at this point. There is no other indication that obdgpslogger isn't collecting data from the vehicle.

I'm using an OBDLink SX cable connected to my 1996 Hummer. I have verified, with a newer Macbook running OBD Auto Doctor, that data is being read from the truck.

Does the message "Couldn't get obd bytes for cmd 00" indicate that no OBD data is going to be read?

Any thoughts on what else to try?
 Thanks,
 -Matt
