   L3 turns off while L2 keeps flashing when your phone has joined. A “No Internet” warning is normal; choose “Stay connected.”

   Use your phone’s browser, not the app. While connected to the module hotspot, open http://192.168.4.1/ or http://jkbms.local/.

   Enter your router’s 2.4 GHz WiFi name and password. Set a unique local device name, such as jkbms123, then select “Apply configuration.”
