First and foremost, kudos to chunkyks for writing this interesting application. I have been looking for something like this that runs on *ix for quite some time, ever since I bought a eeePC 900A on sale & installed Xubuntu on it. I am by profession an analyst and the idea of logging this data for my own vehicles gives me a warm & fuzzy feeling.

I expect to make the jump, hardware-wise, with a purchase of the OBDII & GPS hardware, but would like to confirm a few things, first. (I have searched this sub-forum for a few of these terms and came up with bupkis.)

1. Is OBD GPS Logger wholly focused on output?

I read the module documentation and saw nothing about inputs to manipulate the OBDII status.

My point here is that, say I log some OBDII code, investigate & repair it. I would then like to clear the codes and/or the Check Engine light after the fact.

2. If my understanding is correct (no inputs, no code clearing, etc.), is there a recommended *ix-friendly application to clear codes and turn off the Check Engine light?

All the other software of this type I have investigated has run on Windows. I'd like to keep this all neat & clean and running on my itty bitty eeePC 900A (Xubuntu).

Thank you for your time. ]]> OBDII GPS Logger jfruser http://www.mp3car.com/vbulletin/obdii-gps-logger/137224-obdii-_inputs_-check-engine.html obdgpslogger takes forever to open serial port http://www.mp3car.com/vbulletin/obdii-gps-logger/137153-obdgpslogger-takes-forever-open-serial-port.html Mon, 09 Nov 2009 16:07:53 GMT i've got an obdpro and linuxice upgraded to 9.10. I run obdgpslogger -s /dev/ttyUSB1 which is my obdpro device and obdgpslogger reports "opening serial port, this can take a while". For the next 2-3 mins, it says that. I look at my obdpro and i can occasionally see a light flicker other than the normal power on light (i think it may be a Rx or Tx light on the PC side).

After the 3 mins, logger reports that it opened the device up correctly, the scantool failed to respond to command "00", spits out a couple sqlite create table errors and then goes silent.

I don't see it exporting dbus signals :( and nghost doesn't see them either.

any hints? are all the lights on the scantool supposed to light up?

My USB GPS device is pl2303. 1) Making gpsd work a) Copy /lib/udev/rules.d/40-gpsd.rules to /etc/udev/rules.d/40-gpsd.rules b) Edit /etc/udev/rules.d/40-gpsd.rules.... So, finally I have obdgpslogger and gpsd both working with udev hotplug, on ubuntu 9.04

My USB OBDII devices are FTDI.
My USB GPS device is pl2303.

1) Making gpsd work

a) Copy /lib/udev/rules.d/40-gpsd.rules to /etc/udev/rules.d/40-gpsd.rules
b) Edit /etc/udev/rules.d/40-gpsd.rules. Comment out the line for idVendor 0403 and idProduct 6001, and modify the two pl2303 lines so that the permissions will let gpsd access it:

Code:

# Prolific Technology, Inc. PL2303 Serial Port

SYSFS{idVendor}=="067b", SYSFS{idProduct}=="2303", SYMLINK="gps%n", MODE:="0666", RUN+="/lib/udev/gpsd.hotplug.wrapper"

# ATEN International Co., Ltd UC-232A Serial Port [pl2303]

SYSFS{idVendor}=="0557", SYSFS{idProduct}=="2008", SYMLINK="gps%n", MODE:="0666", RUN+="/lib/udev/gpsd.hotplug.wrapper"

c) Edit /lib/udev/gpsd.hotplug.wrapper
Take out the line

Code:

. /lib/udev/hotplug.functions

and put this there instead:

Code:

wait_for_file() {

        [ -e "$1" ] && return 0

        local count=0

        while sleep 1; do

                let count=count+1

                 [ -e "$1" ] && return 0

                if [ $count -gt 60 ]; then

                        return 1

                fi

        done

}

d) sudo dpkg-reconfigure gpsd
Launch on boot - yes
Leave the automatic device list empty
Should gpsd handle devices automatically - yes
Options to gpsd: "-F /var/run/gpsd.sock"

2) Make obdgpslogger hotplug work

a) Put this in /etc/udev/rules.d/40-ftdi.rules

Code:

SUBSYSTEM!="tty", GOTO="ftdi_rules_end"

ACTION=="add", SYSFS{idVendor}=="0403", SYSFS{idProduct}=="6001", RUN+="/usr/local/bin/obdgpslogger -ms /dev/%k"

LABEL="ftdi_rules_end"

b) Configure obdgpslogger to do what you want
Edit /etc/obdgpslogger [if it doesn't exist, just create it]. Set it to put the logfile in the right place:

Code:

log_file=/media/usbthumb/carlog.db

If you have a device that defaults to 38400 instead of 9600 [eg, an OBDLink], then you also need to put that in the config file:

Code:

baudrate=38400

The obdgpslogger half is covered in a bit more detail in doc/auto_launch in your svn checkout
