# GPS and Temperature montor.
## Pi setup
turn ssh server on
turn x off to save memory, boot to command line.
turn on i2c, 1 wire,
## gpsd setup
Could use the tty directly and parse the NMEA stream, however when this was tried with serialport the
cpu load was at 76%, whereas with gpsd its at 15%, so going with gpsd for the moment.
sudo apt-get install gpsd gpsd-clients
sudo adduser pi dialout
cat << EOF > /etc/defaults/gpsd
# Devices gpsd should collect to at boot time.
# They need to be read/writeable, either by user gpsd or the group dialout.
DEVICES="/dev/serial/by-id/usb-067b_2303-if00-port0"
# Other options you want to pass to gpsd
GPSD_OPTIONS=" --speed 4800 "
# Automatically hot add/remove USB GPS devices via gpsdctl
USBAUTO="true"
pi@raspberrypi:~ $

sudo systemctl stop gpsd.socket
sudo systemctl start gpsd.socket
gpsmon
## SMS
Tried to use gammu, but it was unreliable so sms handling is done in node which seems very reliable.
Used https://www.npmjs.com/package/serialport-gsm
See https://wiki.dd-wrt.com/wiki/index.php/Mobile_Broadband#Huawei for prefered user port.
use udevadm info --name=/dev/ttyUSB3 --attribute-walk to get the interface numbers.

## wwlan0
The modem as a cbc_ether device that shows up as wwan0 but there doesnt seem to be a
good way of configuring its router, so I disabled.
cat << EOF > /etc/modprobe.d/raspi-blacklist.conf
blacklist sr_mod
blacklist cdc_ether

# udev
Tried several times to create stable symlinks to devices, but found /dev/servial/by-id to work better.
this doesnt work.

# Modeswitch
Didnt need to modeswitch the E173 as it happens anyway, but if I did, here is some info.
12d1:1446 is the default
USB Modem 12d1:1436
If mode switing is required then its something like this.
sudo usb_modeswitch -v 0x12d1 -p 0x1446 -M 55534243000000000000000000000011060000000000000000000000000000 -V 0x12d1 -P 0x1436 -s 50 -m 0x01

sudo apt-get install ppp usb-modeswitch wvdial

To start ppp0, then ping 8.8.8.8, the packet latency should be different from wired.

## Upload data periodically
Perfiosly used go get github.com/google/skicka but that has a 400MB footprint installing go and takes forever to install
https://developers.google.com/drive/api/v3/quickstart/nodejs
now uses node drive.js which uploads from a crontab
## Crontabs
one of periodic upload.
## service
npm install pm2 -g
pm2 startup
pm2 start index.js
pm2 save
## Install node and npm
sudo apt-get install nodejs npm
## Install tracker code and sms responder.
git clone
cd tracker
npm install
# Todo
* [x] Use GPS tty directly in node to reduce cpu usage - total fail. node uses 76% using serialport and very simple processing, gpsd uses 15%, stick with gpsd.
* [x] Make gammu-smsd stable when USB fails or use gammu cli or go direct to tty - went direct to modem using seralport-gsm node module which is well supported and works.
* [x] Implement sync upload
* [x] Do periodic restart on gpsd which seems to hang, perhaps a periodic reboot would be better.
* [x] add systemd service for the tracker logger
* [x] decide how to sync time, probably ntpd on start if the gpsd doesnt do it.
* [x] create uploader in node and run periodically or on demand from sms message.
