What port is NMEA data transmitted on? FloatHub Support Team August 05, 2016 23:17 Follow Your FloatHub device will transmit NMEA data over WiFi. This can be used by many chart plotting and navigation packages/applications. The default port is 2319, although this can be changed via FloatHub's web interface on the "Other Settings" page.

Select "Only Private NMEA" to restrict connections in this way. Edited by FloatHub Support Team August 05, 2016 23:17 Please sign in to leave a comment.
