Yes, I am using a GoFree WiFi to transmit halo radar
data to a PC running openCPN quite successfully. It has not been slow at all (No missing radar spokes with both ranges running) after I enabled the multicast mode in the GoFree router. Based on the info in the advanced set-up guide from Simrad
, multicast is disabled by default to keep the radar data from clogging the GoFree bandwidth in case you have many devices using the router. Since the radar data is really what I want, I enabled multicast and the radar data passes through at high speed. I have also made sure there are no slow WiFi devices on the net as the router defaults to the slowest transmission
rate of any connected device.
My GoFree is hardwired to the radar control box
, and hardwired to the chart plotter, but is wireless to the OpenCPN PC (Windows 10, 802.11N) The usual connection is to hardwire directly from the radar box to the chartplotter
, but the GoFree passes the traffic correctly (as it should)
I can control the radar from either the PC or the chartplotter
. The display changes on both displays when I make a change on either one. I see no reason the set-up shouldn't work
with the other Simrad
radars and other Wifi Routers as long as multicast can be enabled.
