I have a base and rover M8P set-up and connected to my Windows 10 laptop (which has be configures to >1 GNSS using the selection guide for GNSS USB drivers).
I am following the instructions set out in section 21 "logging" of the u"-blox M8 receiver description" manual. Which includes creating a new file in UBX - LOG - CREATE and recording data using UBX - CFG - LOGFILTER.
I have been able to get the rover to receive and store data to the flash memory when attached through the USB to my laptop. I have not been able to disconnect the rover from the USB and for it to begin to log and save data to the flash memory once it is powered up on its own battery supply- which is what I would like to do.
I have tried various combinations (apply all filter settings and log once per wake up) of set-ups in the UBX - CFG - LOGFILTER but with no success. I assume it could be another setting that I have not been able to find to enable this. Does anyone have any suggestions on how I could rectify this?
