A connected coffee machine module that works with the OOCSI server
Just send an OOCSI request to the coffee_channel containing the following data.
- caffee_who int which is the unique identifier of orderer. Cannot be 0.
- caffee_amount int with the number of cups you want to order
- caffee_time_to_wait int time (in minutes) you want the coffee to be ready
- caffee_command String (optional) you can use the command "add" to order
Example request:
// order a coffee
oocsi .channel("coffee_channel")
// some kind of user identifier, cannot be 0
.data("caffee_who", int(random(1,99999)))
// the amount of coffee you want
.data("caffee_amount", 3)
// how long to wait for the coffee, in minutes
.data("caffee_time_to_wait", 2)
.send(); You can change or delete your order by sending an OOCSI request to the coffee_channel containing the following data.
- caffee_command String use "change" to change the order or "remove" to remove the order
- number int order number, can be retrieved from the status updates
- caffee_who int which is the unique identifier of orderer. Cannot be 0.
- caffee_amount int with the number of cups you want to order
- caffee_time_to_wait int time (in minutes) you want the coffee to be ready
Example request for changing an order:
// change a coffee order
int order_number = 1; // should be retrieved from the status update messages
oocsi .channel("coffee_channel")
// command
.data("caffee_command", "change")
// order number
.data("number", order_number)
// some kind of user identifier, cannot be 0
.data("caffee_who", 9001)
// the amount of coffee you want
.data("caffee_amount", 3)
// how long to wait for the coffee, in minutes
.data("caffee_time_to_wait", 2)
.send(); Example request for deleting an order:
// delete a coffee order
int order_number = 1; // should be retrieved from the status update messages
oocsi .channel("coffee_channel")
// command
.data("caffee_command", "remove")
// order number
.data("number", order_number)
.send(); You can receive status updates on your coffee order by listening to the coffee_channel. Different messages will be send containing the following data:
- number int which is the order number, this can be used to track, change or cancel the order.
- output_type int which is the identifier of output message type, ranging from 1 to 4.
- amount int number of cups ordered
- who int unique identifier of orderer
- message String description of output message
There are four different messages (output_types) that you can expect.
- output_type = 1: Order is confirmed
- output_type = 2: Order cannot be confirmed (e.g. because the queue on the module is full)
- output_type = 3: The order is being prepared
- output_type = 4: The order is ready
- output_type = 5: The order has been changed
- output_type = 6: The order cannot be found
- output_type = 7: The order has been removed
Example of receiving the messages:
void handleOOCSIEvent(OOCSIEvent event) {
int output_type;
int amount;
int who;
int number;
String message;
output_type = event.getInt("output_type", 0);
switch(output_type){
case 1: // output_type == 1
message = event.getString("message");
amount = event.getInt("amount", 0);
who = event.getInt("who", 0);
number = event.getInt("number", 0);
println("ORDER CONFIRMED:");
println("\t Amount: "+amount);
println("\t Who: "+who);
println("\t Message: "+message);
println("\t Order number: "+number);
println("");
break;
case 2: // output_type == 2
message = event.getString("message");
amount = event.getInt("amount", 0);
who = event.getInt("who", 0);
number = event.getInt("number", 0);
println("ORDER NOT CONFIRMED:");
println("\t Amount: "+amount);
