No NVS output #5

Hi. I am trying to connect a NVS evaluation kit to RtkGps using a Motorola Moto G. The USB device is detected and I get green icons for the input stream, but then I see no SNR, no sky plot, anything. Many thanks - Ricardo.

Hi Ricardo , Could you get data from your evalutaion kit ?

courdi95 commented 9 years ago

I am interested also by the way you are using this eval kit.

By default, the NVS BINR protocol is has is 8-O-1 parity and is likely not getting understood by RtkGPS. Check out page 8 of 91 (Data Transmission Line) - http://www.nvs-gnss.com/support/documentation/item/download/39.html

Thanks @jmrickerby but I have set exactly that config in RtkGPS and it still does not work. I do not understand your statement "is likely not getting understood by RtkGPS". It works perfectly on a PC. Cheers.

rpiriz - RtkGPS is not rtklib. With rtklib on the PC, you can configure the 8-Odd-1 parity setting on the Input - Serial configuration. To the best of my knowledge, serial settings are not working in RtkGPS. (Don't let USB distract you, the serial data format still needs to be configured. I got an eval firmware flash for the nv08-csm with no parity, and it works with RtkGPS - but it's not an ideal situation.)

@jmrickerby : thanks for the info. I will ask NVS for a firmware with no parity to see if that solves the problem. Kind regards.
