NMEA activation is synchronized on all devices connected to the same Wi-Fi router (NMEA gateway, multiplexer, onboard router). Therefore, disabling NMEA on one device, such as your smartphone, disables NMEA on other devices in use, such as tablets or computers.

You have two options in the above case:

1. Disconnect your smartphone from the Wi-Fi router to continue using Navimetrix in Internal GPS mode. You will no longer receive the data stream and your position will be that of your smartphone.
   • If your NMEA router is simultaneously connected to the internet via a Cellular SIM card, you should not disable NMEA on your smartphone because synchronization also occurs via the internet.
   • Offshore, offline, you can disable NMEA unless your router is connected to a Starlink antenna.
2. Close NavimetriX on your smartphone.
