You can use the import/export configuration in the Android app.

if you want only the configuration, read the part of the memory that corresponds to the littlefs filesystem. In case of the heltec v3 its

start 0x300000 and size 0x100000

You need to decode/mount the littlefs and find the proto files with the device settings
