Command Resource

---

The Command resource enables you to exchange machine-to-machine messages with SMS-capable devices. For example, you could use a Command resource to instruct a device to take a sensor reading.

While SMS is used as the transport, the SIM does not require an addressable phone number to receive a Command. This is the major distinction from KORE's Messages resource, which can be used for conversational messaging.

Any SMS message sent from a SIM to a pre-determined phone number — see Receive a Command from a SIM — is interpreted as a Command and sent to the Command callback URL of the Sim resource.

Commands can be sent and received using the SMS text mode or binary (PDU) mode. Text-mode Commands have a maximum length of 160 single-byte characters. Binary-mode Commands have a maximum length of 140 bytes.

To receive and process a Command sent to your device, you will interface with the modem directly, probably using AT commands. You should consult with the module manufacturer's documentation for information about receiving SMS messages.

---

Asynchronous resources

The Command resource performs asynchronous operations. To receive an asynchronous notification when a Command resource has finished updating, provide a callback URL, and optionally a callback method, GET or POST, when you create the Command.

---

Retention period

Commands are retained for 30 days from the time they are created. Commands older than 30 days will no longer be readable from this resource.

---

Possible values:

sms

ip

---

delivery_receipt_requested boolean

Whether to request a delivery receipt.

Possible values:

queued

sent

delivered

received

failed

---

direction enum<string>

The direction of the Command. Can be to_sim or from_sim. The value of to_sim is synonymous with the term mobile terminated, and from_sim is synonymous with the term mobile originated.

Possible values:

from_sim

---

date_created string<date-time>

The date and time in GMT when the resource was created specified in ISO 8601 format.

---

date_updated string<date-time>

The date and time in GMT when the resource was last updated specified in ISO 8601 format.

---

url string<uri>

The absolute URL of the resource.

Status values

Status	Description
queued	The Command is queued in our network waiting to be sent to the SIM.
sent	The Command has been sent to the SIM.
delivered	The Command has been delivered to the SIM. For to_sim Commands only.
received	The Command has been received from the SIM. For from_sim Commands only.
failed	The Command has failed to be transmitted.

---

Create a Command resource

Creating a Command resource sends the command to the SIM.

Callback values

Outgoing Command delivery is asynchronous, so we recommend that you pass a callback URL when you create the new Command.

When you provide a callback URL, we call it when the attempt to send the Command completes.

If the CallbackMethod parameter was set to POST, or not provided, the callback parameters are delivered as HTML form parameters. If the CallbackMethod parameter was set to GET, the callback parameters are delivered as a query string.

Send a Command to a Sim.

POSThttps://programmable-wireless.api.korewireless.com/v1/Commands

Body

application/x-www-form-urlencoded

Command*string

The message body of the Command. Can be plain text in text mode or a Base64 encoded byte string in binary mode.

Simstring

The sid or unique_name of the SIM to send the Command to.

CallbackMethodenum

The HTTP method we use to call callback_url. Can be: POST or GET, and the default is POST.

GETPOST

CallbackUrlstring (uri)

The URL we call using the callback_url when the Command has finished sending, whether the command was delivered or it failed.

CommandModeCommandMode (enum)

The mode to use when sending the SMS message. Can be: text or binary. The default SMS mode is text.

textbinary

IncludeSidstring

Whether to include the SID of the command in the message body. Can be: none, start, or end, and the default behavior is none. When sending a Command to a SIM in text mode, we can automatically include the SID of the Command in the message body, which could be used to ensure that the device does not process the same Command more than once. A value of start will prepend the message with the Command SID, and end will append it to the end, separating the Command SID from the message body with a space. The length of the Command SID is included in the 160 character limit so the SMS body must be 128 characters or less before the Command SID is included.

DeliveryReceiptRequestedboolean

Whether to request delivery receipt from the recipient. For Commands that request delivery receipt, the Command state transitions to 'delivered' once the server has received a delivery receipt from the device. The default value is true.

Receive a Command from a SIM

To receive a Command from a SIM — called a "mobile-originated" Command — you should create or update an existing Sim instance and provide a CommandsCallbackUrl property. Optionally, you may also include a CommandsCallbackMethod property.

When a SIM sends an SMS message to the reserved phone number 2936, a Command resource will be created, and your Commands Callback URL will be invoked. The callback request will include the following parameters.

Parameter	Description
CommandSid	The SID of this Command.
SimSid	The SIM this Command was sent by.
SimUniqueName	The sending SIM's friendly name, if it has one.
Command	The body of the Command message. In text mode, this value can be up to 160 characters of text. In binary mode, this value is a Base64 encoded byte string with a maximum size of 140 bytes.
Status	Will always be the string received.
ApiVersion	The version of the API that your initial request was made to.
AccountSid	The SID of the Account that this Command belongs to.
CommandMode	A string representing which mode the SMS was received as. May be text or binary.
