Yea thanks, I don’t get out much.... well, 1 hour a day but then only to the yard but I spend most of that time trying to not get shanked.

See @SquirrelMaster I'm telling you guys we need to just design the damn RDForum bunker. All of us here are on-board with the not-getting-shanked crowd. What are we waiting for.

Bumping this thread up in hopes of some knowledgeable people...

I have two of these StealthOne units installed in my E38 and E39 BMWs. I love them, BUT, they make the V1 run in legacy mode, so I cannot run the V1C with JBV1 at the same time as this unit is hooked up.

Has anyone picked apart the firmware code or know what about it is forcing the V1 to legacy mode? (Obviously it was designed and programmed before V1's ESP). I'm wondering if there is some code or communication protocol that I could update so it doesn't force legacy mode on the V1.

Thanks

Unfortunately the ESP specification calls for the V1 to go into legacy mode when a legacy device is detected on the serial bus (legacy devices pull up voltage during a specific window to announce themselves to the V1).

Without the StealthOne device being updated by the manufacture to support ESP and not the legacy remote display protocol, there's no easy way to run it with ESP devices.

Someone could make an ESP to legacy remote display adaptor (ESP to the V1, remote display protocol to the legacy device), but I'm not aware of anyone having made anything like that. V1 accessories are a niche of a niche, etc...

Adding any non-ESP device to a V1 "network" forces the entire network to use legacy mode. I presume this is because both protocols can't be used simultaneously on the same network. At the very least, it may be because V1 can't do both at the same time.

So this is an interesting way to approach the problem, since I've been wanting to figure out how to update the StealthOne interface/protocol to meet ESP standards so it won't force legacy mode. However, adding a device that translates or bridges the communcation, so the V1 only sees ESP, yet the legacy can still communicate seems to be an easier approach. Not sure how the latency would work with something like that, but I wonder if an Arduino could be programmed and used in this purpose...

I wish I had more time for stuff like this :(

This is exactly what's happening because the StealthOne follows the "Legacy standards" I imagine in communicating with the V1.

Further question to mikedotd:

Is the remote display communication very different between ESP and legacy remote displays? (i.e. if there isn't much of a difference in how the ESP vs non-ESP remote displays talk, could it be as easy as changing/reprogramming the StealthOne not to pull up voltage in that "legacy indicator" window?)

I'm not sure how the legacy remote display protocol works, I've only read the ESP specifications that also describe the desired behavior when a legacy device is detected. I *suspect* it's similar to ESP minus the time slice windows for 2-way communication with the V1, but that's only a guess that ESP was a progression of the original remote display and remote audio protocols.

You could definitely use an arduino for something like this, someone has already written an ESP library too: tz1/bluev
