Re: xap-x10 schema question about possible mistakes in the
schema

Hi Jose,
First of all, yes I do believe that is the 'current' X10 schema
but it was also created many years ago when xAP was new. Nowadays it is
not a particularly good schema design as it includes addressing
parameters within the message body (device = X10 address) , a more up to
date approach would use sub addressing, but it is viable.
If you wish to use (and update) it then fine but just to let you
know there has been another X10 xAP connector written that uses the xAP
BSC schema which is more universally understood by many xAP applications
but BSC is supporting only on/off/dim control.

I don't now use X10 myself so I've lost touch with the supported X10
interfaces and I am not sure about Extended code handling within this
updated application - maybe this post from UKHA helps a bit ?

*Hopefully Edward - who wrote the newer X10 connector will respond here
and clarify things a bit.
cheers Kevin

I hope somebody in the group can help me.
The first question is:
Is this the latest version for the xap-x10 schema? Where can I found the
latest schema?
The second question is:
The most used commands are ON, OFF, DIM, BRIGHT, ALL_LIGHTS_ON,
ALL_LIGHTS_OFF and ALL_UNITS_OFF, but the schema also has an annotation for
the other commands defined in the X10 protocol, these are:
•hail_req
•hail_ack
•preset_dim_1
•preset_dim_2
•status_on
•status_off
•status_req
•ext_data
But there is one command defined in the X10 protocol, that is not defined
in the xap-x10 schema, this is "EXTENDED CODE". This command
appear to be similar to "EXTENDED DATA" ("ext_data" in
xap-x10 schema), so I assume that "EXTENDED CODE" may be
"ext_code" in the xap-x10 schema, but it's not defined.
About extended data and extended code commands and events, there will be
necessary another field/s in the message body, because these commands has
two additional bytes of data (for example data and type).
This will be an example for a xap-x10 message body from an extended
command:
xap-x10.event
{
command=ext_code
device=A1 (list of X10 devices)
data=16 (8 bit value)
type=1 (8 bit value)
}
So, if I'm right there will be necessary to:
- add ext_code to the xap-x10 schema
- define the name of the fields for the data bytes for the extended code
and extended data commands and events.

Jose Luis
