Sound Box to Bluetooth communication.

[defor]

Has anyone done any analysis on the protocol and data being shared?

As the Bluetooth adapter works great as a stand alone throttle, I would very much like the ability to remotely operate a few small devices if this were available with a Pi or Arduino connected to the 3-wire communications port.

I'm assuming you are talking about the new Kato bluetooth throttle. I don't have one, so couldn't analize it, but the information available mentions that the system could support turnout control from the application in the future, so the possibility is there. (that would probably need turnout control boxes with digital input) I'm also assuming you would like to use the sound controls in the current application for triggering various events.

Correct- that’s what I’m curious about-

1) triggering events using the sound buttons

2) is it possible to display data using the sound even button labels, as they appear to be populated only once connected...?

 

my assumption is that there’s either an initial reporting out from the sound box When it’s powered up... although this would require the Bluetooth box to store this data about what’s connected to it.

 

OR

 

the sound box responds when asked “what is connected”

”what are your capabilities”

But only when the Bluetooth host device (phone) asks when needed.

 

The second option sounds far reasonable and would be a modern solution. 

 

Just some one brainstorming without any hard data at all

I think the comm. port is probably a 3.3 or 5V based serial port, probably with a dedicated protocol. If someone has both boxes and could take a look at the signal between the two (with a scope), that would help.
