Features
|
||||||
|
========
|
||||||
|
|
||||||
|
* Can be deployed almost anywhere in the world
|
||||||
|
* Designed to allow non-technical users to do all setup/maintenance
|
||||||
|
of deployed phones
|
||||||
|
* Many different phones running KalSMS can be connected to a single server
|
||||||
|
(each phone could forward messages for a different mobile network)
|
||||||
|
* Authenticates with password shared between phone and server
|
||||||
|
* Retries forwarding messages after a delay if there is an error
|
||||||
|
(e.g. due to temporarily broken internet or GSM connection)
|
||||||
|
* Notifies the server of the status of outgoing messages
|
||||||
|
* Forwards incoming MMS messages (pictures/video/audio)
|
||||||
|
* Shows log messages to user to facilitate troubleshooting
|
||||||
|
* Can prevent incoming messages from being stored in Messaging inbox
|
||||||
|
* Can forward messages already received in Messaging inbox
|
||||||
|
|
||||||
|
=============
|
||||||
|
Prerequisites
|
||||||
|
=============
|
||||||
|
|
||||||
|
* One or more Android phones (1.6 Donut or higher) that are
|
||||||
|
registered on a mobile network.
|
||||||
|
* A way for the phones to connect to the internet, either via Wi-Fi
|
||||||
|
or the mobile data service. (Even if using Wi-Fi, mobile data
|
||||||
|
service is required for receiving MMS messages.)
|
||||||
|
* A web server accessible from the public internet
|
||||||
|
|
||||||
|
==========
|
||||||
|
Installing
|
||||||
|
==========
|
||||||
|
|
||||||
|
The general process for installing KalSMS is as follows:
|
||||||
|
|
||||||
|
* Download and install KalSMS on an Android phone, e.g. via
|
||||||
|
http://envaya.org/sg/kalsms or by compiling it from source
|
||||||
|
and using "adb install" on a phone in USB debugging mode
|
||||||
|
* Open the KalSMS app
|
||||||
|
* Click the Menu button, then "Settings"
|
||||||
|
* Configure KalSMS to work with your server by entering:
|
||||||
|
* your server URL
|
||||||
|
* your phone number
|
||||||
|
* the password shared with the server
|
||||||
|
* Choose an interval to poll for new messages
|
||||||
|
* Check "Enable KalSMS?"
|
||||||
|
* Click the Back button to return to the main screen
|
||||||
|
|
||||||
|
Of course, you must also set up the server. It is assumed that
|
||||||
|
you already have some kind of HTTP server; follow the instructions in the
|
||||||
|
Server API section below to learn how to construct a resource that
|
||||||
|
communicates with KalSMS.
|
||||||
|
|
||||||
|
To test if KalSMS has been configured properly and can connect
|
||||||
|
to your server, open the KalSMS app, click the Menu button,
|
||||||
|
then click "Test Connection".
|
||||||
|
|
||||||
|
Additional recommended phone configuration:
|
||||||
|
|
||||||
|
* Prevent Wi-Fi from turning off when the phone sleeps, by
|
||||||
|
going to Settings > Wireless & Networks > Wi-Fi settings >
|
||||||
|
Menu key > Advanced > Wi-Fi sleep policy and select "Never".
|
||||||
|
(Otherwise, you will get connection timeout errors when forwarding
|
||||||
|
messages after the phone goes to sleep.)
|
||||||
|
|
||||||
|
==========
|
||||||
|
Server API
|
||||||
|
==========
|
||||||
|
|
||||||
|
KalSMS communicates with the server via HTTP POST requests which expect an XML response.
|
||||||
|
|
||||||
|
For convenience, KalSMS includes server libraries for certain languages to simplify
|
||||||
|
handling its POST requests and generating response XML.
|
||||||
|
|
||||||
|
These libraries and example code are available in the server/ directory.
|
||||||
|
|
||||||
|
-------------------
|
||||||
|
HTTP Request Format
|
||||||
|
-------------------
|
||||||
|
|
||||||
|
The following parameters are sent by all POST requests from KalSMS:
|
||||||
|
|
||||||
|
"version" ::= <integer>
|
||||||
|
The API version of the POST requests (currently "2").
|
||||||
|
|
||||||
|
This number will be incremented whenever the format of POST requests changes significantly.
|
||||||
|
This allows the server to support phones running different API versions at the same time.
|
||||||
|
If a deployment has many phones running with KalSMS, the server should update its code first,
|
||||||
|
then the phones can be upgraded to the new version of KalSMS as convenient.
|
||||||
|
|
||||||
|
"phone_number" ::= <text>
|
||||||
|
The phone number of the phone running KalSMS, as entered under Menu > Settings.
|
||||||
|
|
||||||
|
This allows the server to differentiate between KalSMS clients if multiple phones
|
||||||
|
are running KalSMS.
|
||||||
|
|
||||||
|
"action" ::= "outgoing" | "incoming" | "send_status"
|
||||||
|
The request action determines the purpose of the HTTP request:
|
||||||
|
|
||||||
|
"outgoing":
|
||||||
|
Poll the server for outgoing messages
|
||||||
|
|
||||||
|
"incoming":
|
||||||
|
Forward an incoming SMS or MMS message to the server
|
||||||
|
|
||||||
|
"send_status":
|
||||||
|
Update the server on the status of sending an outgoing message
|
||||||
|
|
||||||
|
The other POST parameters sent depend on the request action.
|
||||||
|
|
||||||
|
HTTP Headers sent by all POST requests from KalSMS:
|
||||||
|
|
||||||
|
"X-Kalsms-Signature" ::= <text>
|
||||||
|
A signature of the request to verify the phone and the server share the same password
|
||||||
|
(though it doesn't protect against MITM snooping or replay attacks).
|
||||||
|
|
||||||
|
The signature is calculated by the following algorithm:
|
||||||
|
|
||||||
|
1. Sort all POST parameters (not including file uploads)
|
||||||
|
in alphabetical order by the name of the field.
|
||||||
|
|
||||||
|
2. Generate an input string by concatenating:
|
||||||
|
the server URL,
|
||||||
|
each of the sorted POST parameters with their corresponding values, and
|
||||||
|
the password,
|
||||||
|
with a comma in between each element, like so:
|
||||||
|
|
||||||
|
"<serverURL>,<name1>,<value1>,<...>,<nameN>,<valueN>,<password>"
|
||||||
|
|
||||||
|
3. Generate the SHA-1 hash of the input string in UTF-8
|
||||||
|
|
||||||
|
4. Encode the SHA-1 hash using Base64 with no line breaks.
|
||||||
|
|
||||||
|
Additional parameters sent in POST requests with action=incoming:
|
||||||
|
|
||||||
|
"from" ::= <text>
|
||||||
|
The phone number of the message sender.
|
||||||
|
|
||||||
|
"message_type" ::= "sms" | "mms"
|
||||||
|
Whether this message is an SMS or MMS.
|
||||||
|
|
||||||
|
"message" ::= <text>
|
||||||
|
The message body of the SMS, or the content of the text/plain part of the MMS.
|
||||||
|
|
||||||
|
Additional parameters sent in POST requests with action=incoming and message_type=mms:
|
||||||
|
|
||||||
|
"mms_parts" ::= <json_array>
|
||||||
|
Metadata for each part of the MMS. Each item in the JSON array is an object
|
||||||
|
with the following keys and values:
|
||||||
|
|
||||||
|
"name" ::= <text>
|
||||||
|
The name of an additional form field where the content of the MMS part
|
||||||
|
is sent as an attached file.
|
||||||
|
|
||||||
|
"cid" ::= <text>
|
||||||
|
The Content ID of the MMS part. This allows the server to resolve
|
||||||
|
references in the SMIL part of the MMS
|
||||||
|
(e.g. <img region="Image" src="cid:805"/>).
|
||||||
|
|
||||||
|
"type" ::= "application/smil" | "text/plain" | "image/jpeg" | ...
|
||||||
|
The Content Type of the MMS part.
|
||||||
|
|
||||||
|
"filename" ::= <text>
|
||||||
|
The filename of the MMS part, as sent by the sender phone,
|
||||||
|
e.g. "Image001.jpg".
|
||||||
|
|
||||||
|
(Additional fields with the content of each MMS part. Text parts
|
||||||
|
are encoded in UTF-8.)
|
||||||
|
|
||||||

|
||||||
|
response XML).
|
||||||
|

|
||||||
|
The current status of the outgoing message.
|
||||||
|
|
||||||
|
"error" ::= <text>
|
||||||
|
A description of the reason for the error, if the message
|
||||||
|
failed to send; or, an empty string if the message
|
||||||
|
has been sent successfully.
|
||||||

|
||||||
|
--------------------
|
||||||
|
