     <p>A repeater is the fixed radio that stays installed to relay traffic for the mesh. A companion is a second node you use to reach and manage that repeater from the MeshCore mobile app. The flow here is: build if needed, flash and configure over USB, test companion-based setup, then deploy the node.</p>
