Thank you for testing it out. That's right, I'm using PoweredUP app version 3.7.0 on my Android device.

Sure thing! Program: https://www.flickr.com/photos/194475369@N04/51701809348/in/dateposted-public/ Controls: https://www.flickr.com/photos/194475369@N04/51701528801/in/dateposted-public/

The hub's bluetooth will work perfectly while using a Lego remote, or using Lego PoweredUp app program. The problem only happens when using a custom program in the PoweredUp app. It's strange that I'm the only one it seems to be having this problem. I've checked my android phone's settings multiple times and everything is enabled for bluetooth/location, etc. (Other bluetooth devices work fine on my android phone). I just got a new Lego hub and tested it in my train. The same issue happens.

Problem: Powered Up hub Bluetooth disconnects shortly after running a custom program in the Powered Up app Details: I have the Crocodile locomotive that runs perfectly when I'm using the Lego Crocodile program. It will run without the Bluetooth disconnecting. Recently I made a small custom program in the Powered Up app and noticed that the Bluetooth was disconnecting frequently. I've tried a lot of different combinations to see if I could isolate the fault of the problem. 1. (Android device) Ran the Crocodile locomotive using the Lego Crocodile program and timed how long it would run before Bluetooth disconnected - Ran until I stopped it. 2. (Android device) Ran Croc using custom program and timed how long it took for Bluetooth to disconnect - Disconnects in about 30 seconds. 3. (iOS) Ran the custom program with my iPad and Bluetooth stayed connected longer, but still disconnected after about 2 minutes. 4. Got a reply from Lego Tech Support - Mostly checking settings, etc. (I checked settings and didn't find anything I needed to change). 5. Did some more testing - Verified with Android and iOS that the Lego crocodile program will run without Bluetooth disconnecting. Works perfectly (Ran the train for >5 minutes) 6. I tried putting iOS and Android device in different locations to see if that would make a difference; it didn't. I am <5 meters away from the hub. 7. My Android is up to date and so is the Powered Up app. I've probably tried some other things that I forgot to list. I've searched for others with the similar problem but I haven't found anything that matched. Any guidance on why the Bluetooth works fine when using the Lego crocodile program, but when using a simple custom one, it loses connection within minutes? I am planning to run a multi train set up with programmed stops, etc. Thank you in advance for any replies!
