Arduino Ciao DDP Meteor Connector

A DDP Connector to call remote functions of a Meteor server from an Arduino sketch.

You can install Ciao in your Arduino following this guide

Installation and configuration of the connector

1. Insert the host address and port of your Meteor server in the file ddp/ddp.json.conf

2. Copy the DDP Connector folder named ddp to the Arduino Ciao connectors folder (/usr/lib/python2.7/ciao/connectors)

3. Copy the DDP Connector configuration file named ddp.json.conf to the Arduino Ciao conf folder (/usr/lib/python2.7/ciao/conf)

Examples

In all examples you need to include the Arduino Ciao Library and start it on the setup():

#include <Ciao.h>

void setup() {
  Ciao.begin();
}

1. Insert a document into a collection named "Sensors"

void loop() {
  int val = analogRead(0);
  
  String id = "ArduinoSensor";
  String remoteFunction = "/Sensors/insert";
  String parameter = "[{\"_id\": \""+id+"\", \"value\": \""+val+"\"}]";

  Ciao.write("ddp", remoteFunction, parameter);

  delay(500);
}

2. Update a document with id "ArduinoSensor" into a collection named "Sensors"

void loop() {
  int val = analogRead(0);
  
  String id = "ArduinoSensor";
  String remoteFunction = "/Sensors/update";
  String parameter = "[{\"_id\": \""+id+"\"}, {\"$set\": {\"value\": \""+val+"\"}}]";

  Ciao.write("ddp", remoteFunction, parameter);

  delay(500);
}

3. Update or Insert a document with id "ArduinoSensor" into a collection named "Sensors"

void loop() {
  int val = analogRead(0);
  
  String id = "ArduinoSensor";
  String remoteFunction = "/Sensors/update";
  String parameter = "[{\"_id\": \""+id+"\"}, {\"$set\": {\"value\": \""+val+"\"}}, {\"upsert\": true}]";

  Ciao.write("ddp", remoteFunction, parameter);

  delay(500);
}

4. Remove a document into with id "ArduinoSensor" into a collection named "Sensors"

void loop() {
  int val = analogRead(0);
  
  String id = "ArduinoSensor";
  String remoteFunction = "/Sensors/remove";
  String parameter = "[{\"_id\": \""+id+"\"}]";

  Ciao.write("ddp", remoteFunction, parameter);

  delay(500);
}
