More possible commands!

[pedasmith]

Thanks so much for this bit of code!

On my 2-4-2 LionChief, I've found additional commands!

**4b 0 0 ** disconnects from the train]
**4c 0 ** sets the volume of the steam chuffs; 0=quiet 7=loud. Value is just the bottom 3 bits?
**51 ** sets the lights on and off 0=0ff 1=on

I'd like to recommend an addition to the docs: "Note that the speaker for at least some Lionel trains is in the tender; if it's not hooked up, the train will not make any sounds." I was tearing my hair out about why nothing was working until I read the manual and learned that I actually had to hook up the speaker.

The spoken commands for my train are:
The spoken commands are:

00 Random command taken from the list.
01 "This is the operator. Please hold at your location. / Copy. We're holding"
02 "This is the operator. You're clear to proceed. / Roger. We're good to go."
03 "You are clear to depart on signal indication. / Copy that. Clear outbound."
04 "You're clear to proceed. / Yes sir, we're clear to depart."
05 "Train is moving yardmaster. / Have a good run. Out."
06 "Are we clear through the diamond? / Copy that, clear through my limits. "
07 "Dispatcher, we're on time. Are we clear all the way? / Roger that, out."
08 "Please hold at your location. / Copy, we're holding."

sets lights on off? just command 51 or 50?

If you look in my DEV branch i forked you will see i mapped all pitchs. mapped all volumes. Overall Volume. Bell Volume, Whistle Volume, and chug/engine Volume.

I'm not sure about smoke on/off yet. ( i don't have an engine that supports those features)

def set_bell_pitch

0x44020eX where X=> -2...2=> 0xfe,0xff,0,1,2

def set_horn_pitch

0x44010eX where X=> -2...2==> 0xfe,0xff,0,1,2

Here's a link to a Windows C# app that, among other things, can now control a Lionel LionChief train.

Turning the lights on and off are both done with command 51 with a single byte as a parameter: 0=off and 1=on.

Your dev branch isn't visible to me. I'm happy to see the horn pitch, and will add it to my app in a few minute.

checked in my changes to be more visible. My python doesn't look as nice as your C#. I was actually thinking of doing a .NET project. I actually wanted to do it in .net core and run as a docker image for trains. Goal is to be able to run low power raspberry pi to control trains/layouts ect.

Your changes aren't showing up in github? I still only see the one branch, and its last change was 14 months ago.

Sorry I might have been confusing. The changes are in the forked repo under my account not Property404's.

Cool, that all works. I've discovered that command 44 can always take both a volume and pitch for all devices.
In your setup, when you set the bell or horn pitch, you're also setting the volume to a fixed amount (0x0e). You can instead set both the volume and pitch at the same time. The pitch also affects the engine noises and the voice of the person talking.

You've got an accidental typo in https://github.com/idaband/lionchief-controller-raspberrypi in the README.md -- when you give the horn pitch: 44 02 0e XX, and the bell pitch: 44 01 0e XX the horn is number 01 and the bell is 02 (you have them swapped around).

[Property404]

Very cool! Glad some people are finding my code useful

Added commands to the README here: https://github.com/Property404/lionchief-controller/tree/devel

Mind giving it a pass over to see if it's correct?

Also, is horn 1 and bell 2, or bell 1 and horn 2?

[idaband]

@Property404 Yes, thats correct now. Horn is 1 ONE. Bell 2 Two.
@pedasmith had it correct. He also discovered the same thing I realized that setting the pitch is setting the volume.
What I want to learn is how to query for the current settings.

That list looks good. I've figured out how to get some of the data from the train! You have to turn on notify for the 08590f7e-db05-467e-8757-72f6faeb14d3 characteristic. Then write command 01 (plus the starting zero and the final CRC, of course) and the notify will get a single report on the train status. I get stuff that's 8 bytes long:

Example data: 00 81 02 05 01 03 0C 0F
[0] 00
[1] 81 (is an opcode; writing 01 gets opcode 81 in return.
[2] 02
[3] speed
[4] direction 01=fwd 02=reverse
[5] 03
[6] 0C
[7] 0000 11

My Lionel_LionChief_Custom.cs has a comment in the beginning with all of the stuff I've pulled out. There are many commands you can pass in that result in something being notified. The parameter is used in some of the commands. Command 20 can return rather a lot of data depending on the parameter, but so far none of it ever changes.

I'd very much love to figure out how to get the lionel model number from the Bluetooth. So far nothing actually includes it.
