 ### Device Discovery
 
-Devices are discovered by scanning for BLE advertisements with the name prefix `MeshCore-`
+Devices are discovered by scanning for BLE advertisements with known MeshCore device name prefixes. These are currently:
+    - `MeshCore-`
+    - `Whisper-`
+    - `WisCore-`
+    - `HT-`
+    - `LowMesh_MC_`
+
+New device prefixes can be added in `lib/connector/meshcore_uuids.dart`.
