This message now has the ability to simply change the free text message or to change the message and send it ASAP. The message_aggregator reference UDP server application exercises this feature by sending a new free text message on any edit and requesting it be sent by WSJT-X when editing is finished i,e, RETURN pressed or focus moved away. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@5445 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

* WSJT-X Message Formats
|
|
* ======================
|
|
*
|
|
* All messages are written or read using the QDataStream derivatives
|
|
* defined below, note that we are using the default for floating
|
|
* point precision which means all are double precision i.e. 64-bit
|
|
* IEEE format.
|
|
*
|
|
* Message is big endian format
|
|
*
|
|
* Header format:
|
|
*
|
|
* 32-bit unsigned integer magic number 0xadbccbda
|
|
* 32-bit unsigned integer schema number
|
|
*
|
|
* Payload format:
|
|
*
|
|
* As per the QDataStream format, see below for version used and
|
|
* here:
|
|
*
|
|
* http://doc.qt.io/qt-5/datastreamformat.html
|
|
*
|
|
* for the serialization details for each type, at the time of
|
|
* writing the above document is for Qt_5_0 format which is buggy
|
|
* so we use Qt_5_2 format, differences are:
|
|
*
|
|
* QDateTime:
|
|
* QDate qint64 Julian day number
|
|
* QTime quint32 Milli-seconds since midnight
|
|
* timespec quint8 0=local, 1=UTC, 2=Offset from UTC
|
|
* (seconds)
|
|
* 3=time zone
|
|
* offset qint32 only present if timespec=2
|
|
* timezone several-fields only present if timespec=3
|
|
*
|
|
* we will avoid using QDateTime fields with time zones for simplicity.
|
|
*
|
|
* Type utf8 is a utf-8 byte string formatted as a QByteArray for
|
|
* serialization purposes (currently a quint32 size followed by size
|
|
* bytes, no terminator is present or counted).
|
|
*
|
|
* The QDataStream format document linked above is not complete for
|
|
* the QByteArray serialization format, it is similar to the QString
|
|
* serialization format in that it differentiates between empty
|
|
* strings and null strings. Empty strings have a length of zero
|
|
* whereas null strings have a length field of 0xffffffff.
|
|
*
|
|
* Schema Version 1:

|
|
* Message Direction Value Type
|
|
* ------------- --------- ---------------------- -----------
|
|
* Heartbeat Out 0 quint32
|
|
* Id (unique key) utf8
|
|
*
|
|
* The heartbeat message is sent on a periodic basis every
|
|
* NetworkMessage::pulse seconds (see below). This message is
|
|
* intended to be used by server to detect the presence of a client
|
|
* and also the unexpected disappearance of a client. The
|
|
* message_aggregator reference server does just that.
|
|
*
|
|
*
|

* Status Out 1 quint32
|
|
* Id (unique key) utf8

* Dial Frequency (Hz) quint64

|

* DX call utf8
|
|
* Report utf8
|
|
* Tx Mode utf8
|
|
* Tx Enabled bool
|
|
* Transmitting bool
|
|
*
|
|
* WSJT-X sends this status message when various internal state
|
|
* changes to allow the server to track the relevant state of each
|
|
* client without the need for polling commands. The current state
|
|
* changes that generate status messages are:
|
|
*
|
|
* Application start up,
|
|
* "Enable Tx" button status changes,
|
|
* Dial frequency changes,
|
|
* Changes to the "DX Call" field,
|
|
* Operating mode changes,
|
|
* Transmit mode changed (in dual JT9+JT65 mode),
|
|
* Changes to the "Rpt" spinner,
|
|
* After an old decodes replay sequence (see Replay below),
|
|
* When switching between Tx and Rx mode.
|
|
*
|
|
*
|
|
* Decode Out 2 quint32

* Delta time (S) float (serialized as double)
|
|
* Delta frequency (Hz) quint32
|
|
* Mode utf8
|
|
* Message utf8
|
|
*
|
|
* The decode message is send when a new decode is completed, in
|
|
* this case the 'New' field is true. It is also used in response
|
|
* to a "Replay" message where each old decode in the "Band
|
|
* activity" window, that has not been erased, is sent in order
|
|
* as a one of these messages with the 'New' field set to
|
|
* false. See the "Replay" message below for details of usage.
|
|
*
|
|
*
|
|
* Clear Out 3 quint32
|
|
* Id (unique key) utf8
|
|
*
|
|
* This message is send when all prior "Decode" messages in the
|
|
* "Band activity" window have been discarded and therefore are
|
|
* no long available for actioning with a "Reply" message. It is
|
|
* sent when the user erases the "Band activity" window and when
|
|
* WSJT-X closes down normally. The server should discard all
|
|
* decode messages upon receipt of this message.

|
|
*
|
|
* In order for a server to provide a useful cooperative service
|
|
* to WSJT-X it is possible for it to initiate a QSO by sending
|
|
* this message to a client. WSJT-X filters this message and only
|
|
* acts upon it if the message exactly describes a prior decode
|
|
* and that decode is a CQ or QRZ message. The action taken is
|
|
* exactly equivalent to the user double clicking the message in
|
|
* the "Band activity" window. The intent of this message is for
|
|
* servers to be able to provide an advanced look up of potential
|
|
* QSO partners, for example determining if they have been worked
|
|
* before or if working them may advance some objective like
|
|
* award progress. The intention is not to provide a secondary
|
|
* user interface for WSJT-X, it is expected that after QSO
|
|
* initiation the rest of the QSO is carried out manually using
|
|
* the normal WSJT-X user interface.

|
|
*
|
|
* The QSO logged message is sent to the server(s) when the
|
|
* WSJT-X user accepts the "Log QSO" dialog by clicking the "OK"
|
|
* button.
|
|
*
|
|
*
|
|
* Close Out 6 quint32
|
|
* Id (unique key) utf8
|
|
*
|
|
* Close is sent by a client immediately prior to it shutting
|
|
* down gracefully.

* Id (unique key) utf8
|
|
*
|
|
* When a server starts it may be useful for it to determine the
|
|
* state of preexisting clients. Sending this message to each
|
|
* client as it is discovered will cause that client (WSJT-X) to
|
|
* send a "Decode" message for each decode currently in its "Band
|
|
* activity" window. Each "Decode" message sent will have the
|
|
* "New" flag set to false so that they can be distinguished from
|
|
* new decodes. After all the old decodes have been broadcast a
|
|
* "Status" message is also broadcast. If the server wishes to
|
|
* determine the status of a newly discovered client; this
|
|
* message should be used.
|
|

*
|
|
* Halt Tx In 8
|
|
* Id (unique key) utf8
|
|
* Auto Tx Only bool
|
|
*
|
|
* The server may stop a client from transmitting messages either
|
|
* immediately or at the end of the current transmission period
|
|
* using this message.
|
|
*
|
|
*
|
|
* Free Text In 9
|
|
* Id (unique key) utf8
|
|
* Text utf8
|
|
* Send bool
|
|
*
|
|
* This message allows the server to set the current free text
|
|
* message content. Sending this message is equivalent to typing
|
|
* a new message (old contents are discarded) in to the WSJT-X
|
|
* free text message field or "Tx5" field (both are updated) and
|
|
* if the Send flag is set then clicking the "Now" radio button
|
|
* for the "Tx5" field if tab one is current or clicking the
|
|
* "Free msg" radio button if tab two is current. It is the
|
|
* responsibility of the sender to limit the length of the
|
|
* message text and to limit it to legal message characters.
