Issues with the Wi-Fi DCS App Ver 4.0 (Nov 2024)

Well, this is just a sample of one, but I did manage to add and operate two engines successfully.  It took two tries, the first time the second one added and started up, then I couldn't talk to it anymore.  I could still operate the first one however.  I cycled power and tried again and I was able to add and operate the two engines.  This is with the 4.0 DCS app, the WIU, and a Rev. L TIU.

I have DCS App v4.0.0 on my android, two WIU/TIU pairs.

In my case, after my android screen goes to sleep and I wake it by pressing the power button, any engines previously active become inactive.

If you change the settings for your app to allow it to use battery in the background, your phone will not disconnect from Wi-Fi and the DCS app will be allowed to keep communicating with the WIU even though your phone is "sleeping".

Optimized is the default option assigned to all apps, changing to Unrestricted will give the app more control to keep communicating.

Will this update do anything positive for my DCS Explorer?

Thanks,

No. Unless MTH makes the Standard upgrade available for the Explorer to allow more engines and access to all engine features, it will operate the same.

Thanks @gunrunnerjohn for doing some testing. I am having the same issues today (losing connection to the TIU with the "No WIU/TIU/WTIUs Found".)

I switched the WIU to the "MTH Wi-Fi Network" and the same issues persist. As I stated earlier, everything was functioning fine before I updated the DCS app to the new version 4.00.

I am using a Rev. L TIU updated to the latest V6.10 version and a WIU using the latest V1.10 version. I am running the DCS app on an iPhone that is using iOS version 17.7.

Is nobody else having this issue after updating the DCS app to version 4.0.0? Luckily, I still have an old handheld to use, or I would not be able to run trains. Hopefully this is a bug in the latest app version and an update will be released.

Well, one big difference, I have an Android phone.

I am not having any issues using the MTH Network and rev 4 of the app so far.  Two engines running.   Only difference for me is iPhone 13 with IOS 17.6.1.  

As far as I can tell, the app is set to allow background activity.

This needs to be changed from "Optimized" to "Unrestricted"

I'm afraid that battery setting does not make any difference.

There is no "unrestricted" setting but "not optimized" seems the same. After sleep and reawakening, the engines go inactive.

I hope the manufacturers continue to learn from this. Touchscreen Smartphone apps are no way to run a railroad.

There is on my phone.

Here's the Android info.
