app_rpt IAX Text Protocol
app_rpt application relies on IAX text frame to extend its protocol capabilities and exchange information with other nodes or clients. There does not seem to be any existing documentation for this. This page details the various type of commands in existence as observed "in the wild". This is based a compilation of reading the source code of app_rpt, and reverse engineering of known clients such as IAXRpt and WebTransceiver. As such it's likely to contain errors or misunderstandings. If you have knowledge in some of these areas, please contribute your edits.
T: Telemetry
Format
T <NODE_NB> <CMD>,<PARAMS>
- NODE_NB Node sending message
- CMD Telemetry command ALLCAPS
- PARAMS Optional comma separated list of command specific parameters
Complete
Example
T 51696 COMPLETE
Status
Report connection status for the node. Sent in response to *70 status DTMF command.
Format
T <NODE_NB> STATUS,<NODE_1>,0,<NODE_LIST>
- NODE_NB Node sending message
- NODE_1 Node reporting status
- 0 Unknown
- NODE_LIST List of nodes connected to NODE_1. Each node number is prefixed by a connection mode as follow:
- T Transceive mode, send and receive audio
- R Receive audio only
- C Connection is pending
Example
T 51696 STATUS,51696,0,TWH6GJL-P,R29277
Connected
Node connection succeeded
Format
T <NODE_NB> CONNECTED,<NODE_1>,<NODE_2>
- NODE_NB Node sending message
- NODE_1 Node initiating connection
- NODE_2 Other node connected to
Example
T 51696 CONNECTED,51696,29277
Disconnected
Remote node disconnected
Example
T 51696 REMDISC,29277
Removed Already Connected
Remote node is already part of the network. Note that it could be a direct connection or it could be the node is connected via other nodes.
Example
T 51696 REMALREADY
Connection Failed
Remote node can't be connected to.
Example
T 522540 CONNFAIL,51696
Version
app_rpt module version.
Example
T 51696 STATS_VERSION,161.327
Unknown
T 522540 ARB_ALPHA,123#
L: Linked
Sent periodically by a node to broadcast all node linked to it.
Format
L <MODE><NODE_NB>,<MODE><NODE_NB>,...
- MODE Each node number is prefixed by a connection mode as follow:
- T Transceive mode, send and receive audio
- R Receive audio only
- C Connection is pending
- NODE_NB Linked node
If no other nodes are connected, the list is empty and only L is sent.
K: Key
Sent by a node to update its keyed status
Format
K <TO> <NODE_NB> <KEYED> <LAST_KEYED_X_SEC_AGO>
- TO Destination to broadcast this message to. Usually * seems to indicate all connected nodes.
- NODE_NB Node reporting its keyed status
- KEYED 1 = node is keyed, 0 = node is not keyed
- LAST_KEYED_X_SEC_AGO Number of second since node was last keyed
Example
K * 51696 1 2
Key Query
Message to request other nodes to report their keyed state. Initiating this command results in all connected nodes replying with their keyed status.
Format
K? <TO> <NODE_NB> 0 0
- TO Destination to broadcast this message to. Usually * seems to indicate all connected nodes.
- NODE_NB Node requesting status? Could be * here as well
Example
K? * 51696 0 0
M: Message
Text message. Can be sent as node to node or broadcast to all nodes.
Format
M <TO> <FROM> <BODY>
- TO Destination node number. 0 indicates all connected nodes
- FROM Source node number
- BODY Message content
Example
M 0 51696 Reminder net starts at 10:00 pm PST tonight.
J: ?
Status message reporting repeater frequencies. Seems to be only used in the context of the WebTransceiver client.
Format
J Remote Frequency \n<FREQ> FM\n<OFFSET> Offset\n<POWER> Power\nTX PL <TXPL>\nRX PL <RXPL>\n
Miscellaneous signaling
There are several messages being exchanged that alter the behavior of the app_rpt application. It's unclear as to their purpose.
New Key
Seems that this is meant to be some sort of handshake. When a party receives this command it should send it back.
!NEWKEY!
New Key1
Seems that this is meant to be some sort of handshake. When a party receives this command it should send it back.
!NEWKEY1!
IaxKey
Seems that this is meant to be some sort of handshake. When a party receives this command
!IAXKEY!
it should reply with
!IAXKEY! 1 1 0 0
Disconnect
!!DISCONNECT!!
