Frequently asked questions
Should I always update to the latest version?
It's recommended but not mandatory. Minor and patch updates (v1.9.x → v1.10.x) are safe. For major updates (v1.x → v2.x) you might want to wait until the community has tested.
Do I lose my settings with an update?
No, settings are preserved. Only with a full erase (factory reset) do settings disappear. Backup via the app is possible.
Can I downgrade to an older version?
Yes, you can downgrade by flashing older firmware via flasher.meshcore.co.uk. Note that newer data formats may then not be compatible with older firmware.
How do I know which version I'm currently running?
In the MeshCore app: Settings → Device → Firmware version. Or via the web interface if your device has WiFi. Via CLI: type "version" command.
What is the difference between Companion, Repeater and Room Server firmware?
Companion is for personal devices with screen. Repeater is for network nodes without screen that relay messages. Room Server is for fixed locations with extra features like ACL and guest management.
