Raspberry Pi 2 Green station.

[ArnouldJ]

Hello, 

I want to restart my green station and use a raspberry pi 2 to transmit data. anyone have a tutorial for using a raspberry? Thank you in advance for your assistance.

I don't have a tutorial, but i would be starting with the openwrt tracker:
https://github.com/KiNgMaR/blitzortung_tracker_openwrt
It's compiling nicely on my x86 debian, so it should also work on the raspi;

fetch the package:

Code:

git clone https://github.com/KiNgMaR/blitzortung_tracker_openwrt.git

go to the subdirectory and build the tracker:

Code:

cd blitzortung_tracker_openwrt/package/blitzortung_tracker/src && make

after it compiled, you should have an executable blitzortung_tracker which can be invoked by a script in /etc/init.d/ so it will run on startup. Some example init-scripts are supplied by the package.

Sorry for the late response. I'll try your advice and I'll let you know. Thank you.

The configuration of my Raspberry Pi2 and over and I just finished compiling the tracker that seems to work. Only I do not know which lines to edit in the initscript to operate the tracker with my station. 

Here is the script:

Code:

#!/bin/sh /etc/rc.common
# (C) Copyright 2012 Ingmar Runge <ingmar@irsoft.de>

START=97
APP=blitzortung_tracker
PID_FILE=/var/run/$APP.pid
EXTRA_COMMANDS="check"
EXTRA_HELP="        check Probes if the tracker is running and tries to start it if it isn't."

blitzortung_start() {
    local section="$1"

    local enabled
    config_get_bool enabled "${section}" enable 1
    [ "${enabled}" -eq 0 ] && return 1

    local GPS
    local BAUDRATE
    local GPS_BAUDRATE
    local SERIAL_DEVICE
    local USERNAME
    local PASSWORD
    local REGION

    config_get GPS "${section}" gps
    config_get BAUDRATE "${section}" baudrate
    config_get GPS_BAUDRATE "${section}" gps_baudrate
    config_get SERIAL_DEVICE "${section}" device
    config_get USERNAME "${section}" username
    config_get PASSWORD "${section}" password
    config_get REGION "${section}" region

    if [ "${SERIAL_DEVICE}" = "auto" ]; then
        for f in $(echo "/dev/ttyUSB0 /dev/usb/tts/0 /dev/ttyUSB1 /dev/usb/tts/1" | tr " " "\n"); do
            if [ -e "$f" ]; then
                SERIAL_DEVICE=$f
                break
            fi
        done
    fi

    [ ! -e "${SERIAL_DEVICE}" ] && echo "Serial device not found." && return 1
    [ -z "${USERNAME}" ] && echo "Empty username." && return 1
    [ -z "${PASSWORD}" ] && echo "Empty password." && return 1

    # not checking BAUDRATE, GPS_BAUDRATE and REGION because LuCi's should take care of getting those right
    # and those using the uci command line should know what they are doing.

    start-stop-daemon -S -x /bin/$APP -p $PID_FILE -m -b -- -L -bg $GPS_BAUDRATE -bt $BAUDRATE $GPS $SERIAL_DEVICE $USERNAME $PASSWORD $REGION
}

start() {
    config_load "${APP}"
    config_foreach blitzortung_start blitzortung
}

stop() {
    start-stop-daemon -K -p $PID_FILE -s TERM
    rm -f $PID_FILE
}

check() {
    if [ -e $PID_FILE ]; then
        # check if process accepts signals / is running:
        kill -0 `cat $PID_FILE` >/dev/null 2>&1
        if [ $? -eq 0 ]; then
            echo "Tracker running."
            return
        fi
    fi

    echo "Tracker not running, starting..."
    start
}

I guess that init script is openwrt specific. Depending on the distribution you're running on the RasPi you should find some example init script.
You'll find the parameters need to be set by running ./blitzortung_tracker --help  ;

Code:

****** Blitzortung.org Linux Tracker XT 3 OpenWrt ******

Usage:
./blitzortung_tracker [options] gps_type serial_device [username password region]

Main parameters:
 gps_type         : gps type (SANAV, Garmin, or SiRF)
                    use '-' for no initialization
 serial_device    : serial device (examples: /dev/ttyS0 or /dev/ttyUSB0)
 username         : username (example: PeterPim)
 password         : password (example: xxxxxxxx)
 region           : region (1 = Europe, 2 = Oceanien, 3 = USA, 4 = Japan)

Common options:
 -bt baudrate     : tracker baudrate (alternative: --baudrate)
                    possible values:
                    4800, 9600, 19200, 38400, 115200, 500000, 2500000
                    default = 115200
 -bg baudrate     : gps baudrate (alternative: --baudrate_gps)
                    possible values: 4800, 9600, 19200, 38400 (default = 4800)
 -s               : activate SBAS "WAAS/EGNOS/MSAS" (alternative: --SBAS)
 -p port          : activate HTTP Server on <port> (alternative: --server_port)
                    Note: Do not forward this port to the internet unless you
                    know what you are doing!

Hi, 
I'm trying to run on the same wat on an raspberry pi the tracker, but I think I do something wrong in the command line. 

I use now ./blitzortung_tracker -bg 9600 SiRF /dev/ttyUSB0 user password 1
But I see nothing happened, any tips?
