Hey, thanks for your howto to mod the UT61E.

I used a JDY-10 module, which works so far.

Log 2021-01-07 17_07_25.txt.txt

I assume that the UUID is right (the first two zeros are actually there)
ut61E-app-uuid

but the app can't pick up the stream.
ut61e-app

The received binary streams seems to be correct. Currently I can't verify it with ble-serial. Neither ble-scan nor the direct connection with ble-serial works so far.

The UUID looks correct, but I don't know why this module exposes two characteristics. Is there a datasheet that explains this?

Can you post a logcat as well?
You can filter for this app by running: adb logcat --pid=$(adb shell pidof -s jk.ut61eTool)

Looks like it is not receiving any notifications. I assume this is because your module needs explicit enabling of notifications.
Possible reason: https://stackoverflow.com/questions/22817005/why-does-setcharacteristicnotification-not-actually-enable-notifications

I have added setup code that should fix this, please try this build: Application-release.zip
You have to rename the .zip to .apk again (GitHub does not allow the upload otherwise here) and you might have to uninstall the Play Store version first, if the installation does not work.
