3.1.9 NTWB1 Connections & NMEA Repeaters
The NTWB1 can make simultaneous TCP and UDP connections but only
the TCP connected device will receive data from the NMEA connection of
the NTWB1.
However, data from other devices can be simultaneously passed to other
devices connected to the NTWB1 via UDP while the TCP connection is
active. This means if you have a device running software which can act as
an NMEA repeater such as OpenCPN running on a PC, you can have a TCP
connection for the NMEA data from the NTWB1 to OpenCPN and then re-
broadcast the NMEA data via UDP to the other devices connected to the
NTWB1. In OpenCPN, create a separate 'output' network connection with
IP address of 169.254.1.255, UDP protocol and a port number in the range
49152 to 65535 The other WiFi devices will need to listen to the port set
in the new output connection of OpenCPN with UDP protocol and IP
address 169.254.1.1
