NAVIO+ and RAW data output

Hi all,

Could someone please give me a step by step guide on how to capture RAW GPS data from the NAVIO+, convert to RINEX and then post process using RTKLIB or any other suitable tool?

I ran the SPI enabled version of RTKLIB on the RPi last night and set it to log to file both the ROVER and and REFERENCE information, however when I attempt to convert these to RINEX using RTKCONV or CONVBIN I am unable to get a file that a solution can be generated for.

Thanks izy
