Xiaoxiang BMS app/software update from wnsnty.xyz????

I downloaded the Carplounge 3.1.1015 and as far as I can tell it is identical to the xiaoxiang 3.1.1015 from the Overkill site. I guess that should not be a surprise, since they are the same version number.

I'll try the xiaoxiang 3.1.1026 version @WingNut has pointed to tomorrow. Thanks for that @WingNut !
 
I sent Steve a message about there being newer versions as discussed here. He updated his site download page to now have the 3.1.1026 version. It seems to have some additional info, but I also think it might be a little less stable. I had to kill and restart it a few times.
 
Hi guys. I'm running Android V3.1.1021 with two batteries and was wondering if there's a way rename the BT connection / the name "xiaoxiang" (shown in the attached screenshot) to something else like Batt1 and Batt2 so I can see which battery's data I'm looking at?

"Parameter View" has Manufacturer and "App Setting" has Device Model. Both of those fields can be edited.

Yes, but changing these has no impact on the text "xiaoxiang" on the dashboard.

Did you hit the commit button? I think it's in the upper right corner. It's been a while since I did mine and I'm not anywhere close to my trailer to test this.
 
The app gets the name from what's entered in the Manufacturer field under Parameter View on first use of the app. It becomes persistent for some reason and later changes don't take affect in 3.1.1026 unless you delete and reinstall the app. It will use the new name on first use of the reinstalled app. I've confirmed that works.

You can have only a single Manufacturer name on the app but can have a unique name for each battery pack's Bluetooth connection. App Setting - Device Model is for the name of each battery pack's Bluetooth connection.

Thanks @WingNut for clarifying this for me!
 
Clearing app data also works to get the new name to show. That's a bit easier/quicker than uninstalling the app. It works the same in v3.1.1015 and v3.1.1026 for me.

Strange behaviour. I managed to change the xiaoxiang to something else as per your instructions. However, I cannot seem to do this renaming anymore. Even if I uninstall the app and re-run the .apk, the first renaming persists. It doen't revert back to xiaxiang after re-running the .apk.

EDIT: aha. It seems that there's a limit to the number of characters. All good now - thanks again!
 
I have used both 1015 and 1021 versions on my Android 8 phone and they both hang, freeze and fail to connect to BT. I clear the cache, try again, maybe after 5 tries the app executes and I get BT connection and can set the parameters, talk about unstable. I will try the 1026 version. Pretty poor software overall. Wish I could code one but not my skill set.
 
Yeah, I think the Android version of the app could use some love. If anyone here has some Android app development experience, I'm sure we would all appreciate some effort. I've mostly gotten used to killing / restarting the app to get connected. I ended up staying on 1015 after giving up on the newer versions for their different but worse issues.
 
My xiaoxiang bms app will recognise the bms via Bluetooth but will never connect completely to show battery parameters. I have tried all versions of the app to no avail. I've tried carplounge bms and got same result. I then tried polinovel 2.0 app and just got basic battery status. Still no way to see parameters and set them. Somebody should kindly help please. Also my lifepo4 pack at 52.5v Screenshot_20210310-101330_CarploungeBMS.jpgScreenshot_20210310-101426_POLINOVEL 20.jpgwill automatically jump to 58v and above immediately the charge controller is turned on, show overvoltage and short down. Testing the battery terminals show 52.5v only hence I'm blaming the BMS.
