Can you run an A-A engine lash up in the LionChief app both are powered.

I'm not really a fan of the phone apps, and there are others on the Forum who hopefully will chime in.  But this recent topic may describe the reasons for what you're seeing:

Bluetooth really is hit or miss.  You have to run  them one forward and one facing opposite direction. Only 1 engine displays on app if they are sold as a pair.

Hello I have the NYC Legacy Sharks 2133250. They are in my Legacy controller as Train #1. When I try to run them in the Lionchief app, it only shows the lead A unit with sound. Both units will run but the 2nd A unit will only connect nose to tail.

What am I doing wrong? Not reading the details in the manual specific to your set. You go to the product support page for your set https://www.lionelsupport.com/...GACY-Sharks-AA-Set_2

In your manual, Lionchief app usage starts on page 21 and has the same message as below.

What you are describing is perfectly normal.

Again, the app will ONLY ever show and list the lead unit, this is because the second A is NOT programmed to show up as an engine and instead you hope and pray it receives the commands that are being received by the lead engine. I didn't design this protocol- so don't shoot me, but yes, that's more or less how it works. Your remote or app connects to the lead engine, while the second A "listens" only, and follows the commands it sees being sent to the lead A.

You are experiencing the limitations of the Bluetooth system as implemented and designed by Lionel.

Also note, in your manual on page 41 regarding muliple unit operation under bluetooth.

Bottom line is still valid from that other topic:

You are experiencing the limitations of the Bluetooth system as implemented and designed by Lionel.

Just another reason why I'm glad I don't use Bluetooth and will stick with my Cab1Ls and Base 1L until they die, or I die.

Actually the opposite is true. Both units are powered A's and only the lead shows up. The second responds the same way so it must be pointed in the same direction as the lead. Therefore Lead A rear to 2nd unit nose.  Maybe someone can tell me different.

Thanks

All my Bluetooth AA sets operate  A<--- direction ---->A.  There is no way to change the way they face via Bluetooth.  Unless they put the wrong board in it.  How about a video of your issue?   Now in legacy you can operate it anyway you want.  Setting it one way in legacy will not change it in Bluetooth operations

Tom These work fine with my Legacy controller. When they are connected tail to tail in Lionchief they pull against one another. When connected tail to nose, they operate exactly the same and run together. My guess is because they are both powered the 2nd unit responds that way. Obviously a dummy would be only a light issue. I just thought it was odd that they are marketed as bluetooth control but not really. Are any of your AA bluetooth combos both powered? What am I missing?

Yes a few of mine are both powered and Bluetooth.  And they go the proper way. I'll try to video it

Here's a YouTube video of my Bluetooth alco FA set both moving in same direction

Amazing. I can't get mine to run that way.

Maybe there's something wrong with them
