====== LANBridge CFLink Protocol ======

The following documentation is for the LANBridge device CFLink protocol messages.\\
The LANBridge also has an on-board RS232 port, for which documentation is available in the [[on-board-rs232-port-protocol|On-Board RS232 docs]].

===== Common Definitions =====

The following communication slots exist on a LANBridge:

  * ''1'' = CFLink slot
  * ''2'' = On-board RS232 slot
  * ''3'' = UDP Broadcasting slot (not available for subscriptions, can only be enabled/disabled via [[hardware:cflink:lanbridge-cflink-protocol#udb-udp-broadcasting-configuration|UDB command]]
  * ''4'' - ''10'' = Reserved for future use
  * ''11'' - ''20'' = Configurable as TCP or UDP communication
===== Queries =====

==== WHO - Device discovery ====

The ''WHO'' query is used to discover what device is at a specific address.\\
The ''WHO'' reply will be automatically broadcast as a notification to the CFLink network when a device is powered up or reset.

=== Data ===

The ''WHO'' query does not have any associated data.

==== SUB - Configure Slot Subscription ====

The ''SUB'' (Subscription) command is used to configure a slot subscription. A subscription is a way to send/receive data between two communication slots on the LANBridge automatically.\\
\\
When subscribing to the CFLink slot, a subscription can be refined to communicate only with a device at a specific CFLink ID and optionally which module.\\
\\
When subscribing to the CFLink slot, a subscription can also handle automatically manipulating the incoming data to wrap it in CFLink protocol formatting, and stripping the CFLink formatting before sending the outgoing data.\\
\\
This allows TCP/UDP communication slots to send basic commands like ''P01:0|P02:0'' and have it automatically wrapped into a CFLink command targeted at a specific device and module to open relays in this example.
And the same in reverse, taking CFLink protocol message and only sending the data segment.\\
\\
See the [[hardware:cflink:lanbridge-cflink-protocol#common-definitions|Common Definitions]] for a list of available communication slots.

> [F2]<ID>[F3]TLANSND[F4]<SLOT#>:<DATA>[F5][F5]
</code>

  * **<SLOT#>** = The communication slot number to send data to. Known as the 'target slot'.
  * **<DATA>** = The actual data to send to the target slot. Hex bytes should be defined in \xFF format. eg. A carriage return is written as \x0D

<code>
// In an effort to reduce network traffic on the CFLink bus, the reply will not contain the <DATA> sent, only the slot it was sent to.
< [F2]<ID>[F3]RLANSND[F4]<SLOT#>[F5][F5]
</code>

=== Example ===
<code>
// Send a command to an ethernet device connected to slot 11, for LANBridge on CFLink ID [02]
> [F2][02][F3]TLANSND[F4]11:Hello World!\x0D[F5][F5]
// Reply
< [F2][02][F3]RLANSND[F4]11[F5][F5]
</code>

=== Error ===

  * 100 = Invalid Slot Number
