+# Telematics Recorder
+
+## Overview
+
+The telematics recorder demonstation application reads the OBD-II vehicle speed and
+engine speed (RPM) messages using the low-level CAN binding, and sends them as JSON
+messages to a MQTT broker for clients to use.
+
+## Configuration
+
+The application has several configurable parameters, which can be configured via the
+INI style file /etc/xdg/telematics-recorder.conf. The parameters are described in the
+following sections.
+
+### General
+
+General configuration consists of the following parameters in the "[General]" section:
+* log_level
+* cellular_enabled
+* gps_enabled
+* check_online
+* device_uuid
+
+#### log_level
+
+Sets the debug logging level, acceptable values are 1 or higher. If the parameter is not
+present, logging is disabled. The default value is no debug logging.
+
+#### cellular_enabled
+
+Enables or disables cellular modem usage, acceptable values are "true" and "false" (case-insensitive).
+The logic enabled by this parameter blocks on a check for cellular modem presence at start up, and
+sets the modem state to online when detected. The default value is disabled ("false").
+
+#### gps_enabled
+
+Enables or disables GPS usage, acceptable values are "true" and "false" (case-insensitive).
+When enabled, the current GPS position will be populated in the events sent to the MQTT broker.
+The default value is disabled ("false").
+
+#### check_online
+
+Enables or disables checking for online status, acceptable values are "true" and "false" (case-insensitive).
+When enabled, the the current network online status will be checked before attempting to send messages to
+the MQTT broker to potentially prevent filling the transmit queue of the MQTT client.
+The default value is disabled ("false").
+
+#### device_uuid
+
+A string representing a unique device identifier. It is used to identify the device in the MQTT messages.
+If not specified, the default value is "e4bbc0a8-f435-4326-9769-d4a2c9f3c18d".
+
+### MQTT
+
+MQTT protocol configuration consists of the following parameters in the "[MQTT]" section:
+* broker
+* port
+* keepalive
+* qos
+* retain
+* username
+* password
+
+#### broker
+
+MQTT broker hostname. Default value is "iot.eclipse.org".
+
+#### port
+
+MQTT broker port. Default value is 1883.
+
+#### keepalive
+
+MQTT protocol keepalive time. Default value is 60 seconds.
+
+#### qos
+
+MQTT protocol quality of service (QoS) parameter, acceptable values are 0, 1, or 2.
+Default value is 0. See "Quality of Service" in [https://mosquitto.org/man/mqtt-7.html](https://mosquitto.org/man/mqtt-7.html)
+for a description of the QoS settings.
+
+#### retain
+
+MQTT protocol message retain parameter, acceptable values are "true" and "false" (case-insensitive).
+Default value is "true". See "Retained Messages" in [https://mosquitto.org/man/mqtt-7.html](https://mosquitto.org/man/mqtt-7.html)
+for a description of the message retention mechanism.
+
+#### username
+
+MQTT broker username string if required. Default value is none.
+
+#### password
+
+MQTT broker password string if required. Default value is none, and only relevant in conjunction
+with the username parameter.
+
+### Event
+
+Event configuration consists of the following parameters in the "[Event]" section:
+* update_period
+
+#### update_period
+
+The period in seconds for sending messages to the MQTT broker, acceptable values are 0 or higher.
+A value of 0 means send a message to the broker for every CAN event that comes in. The default value is 10.
