Unfortunately no. I also stumbled over this sentence but I think they mean the update rate of the current probe, i.e. they did measuer the supply current 10 times per second. > > Is there any GTA04 board, which already has a W2SG0084i installed? Yes, about 50 or 80 (I don't remember the exact figure) since the W2SG0004i was EOL and could easily be swapped. Unfortunately we don't have a mapping to serial numbers. > If > so, we could try to query/set the output rate according to chap. 5 "NMEA > Input Messages", using the message ID 103. That one unfortunately only allows to specify the reporting rate in multiples of 1 second, i.e. up to 255 seconds. But not 1/10 sec. > Also chap. 6.2 "OSP Input > Messages" look interesting, especially message 0x81. > > Cheers, > Lukas Maybe someone knows a good technical contact to Wi2Wi? I only have very indirect support though a distributor.
