Many thanks , Raphael.
I’m evaluating the module in base mode: $PQTMCFGRCVRMODE,W,2*29 # set receiver to base mode,which is the only way to output (rtcm) messages but at 1Hz; however it is not possible to save the output of RMC and GGA that are the (2) only ones to support a frequency higher than 1hz, also does not save even $PAIR432,1*22 # output RTCM3 MSM7 messages. I say this because it would be the only way to make it work with programs like rtklib; can You send a note & [ +] to the developers to correct the firmware.(2) edited but only raw data can do althougth unusable…
Thank you again for your valuable support.
