Check your phone’s WiFi settings to ensure WiFi is enabled and that it’s trying to connect to the correct OBD2 adapter network.

Verify the Adapter’s WiFi Signal

Make sure the adapter is emitting a signal. Sometimes, a simple reset can resolve the issue. Unplug the adapter from the OBD2 port and plug it back in.

Troubleshooting Your Android Phone’s WiFi Connection
