- Changed the default database path in config.ini.example and related files from 'bot_data.db' to 'meshcore_bot.db' for consistency across modules. - Adjusted final hop proximity scoring parameters in config.ini.example to reflect updated distance normalization and thresholds, enhancing scoring accuracy for LoRa networks. - Updated documentation to clarify the shared database usage between the bot and web viewer.

|
One-off migration: copy packet_stream from a separate web viewer database
|
|
(e.g. bot_data.db) into the main bot database (e.g. meshcore_bot.db).
|
|
|
|
Use this when switching from split databases to the shared database so you
|
|
don't lose packet stream history. Run with bot and web viewer stopped.
|
|
|
|
Usage:
|
|
python3 migrate_webviewer_db.py <source_db> <target_db>
|
|
|
|
Example:
|
|
python3 migrate_webviewer_db.py bot_data.db meshcore_bot.db
