ninjatrace will be a live tracing system and drivers logbook for raspberrypis attached to a vehicles.

The architecture is based fully on distributed erlang/otp and everything else erlang and the BEAM provides out of the box.

A running ninjatrace application is either started as a server or a device.

Devices are raspberry pis that are mounted on the motorcycle (or other vehicle) that should be tracked by the system. A device generates data via multiple sensors (gps, thermal etc). Devices connect to at least one well-known server using erlang distribution.

Servers are supposed to manage all connected devices and provide an API to access the data produced by each device.

The executing user must have the rights to access the serial port /dev/ttyS0. Ideally by being a member of the uucp (or corresponding) group.

$ sudo gpasswd -a USER uucp

Quectel L80-M39 Settings The following stty serial settings must be provided for this device: $ stty -F /dev/ttyS0 raw speed 9600

$ rebar3 compile

First pem containing a certificate and the private key must be generated:

$ openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
$ cat cert.pem key.pem > merged.pem
