3dr solo rtk rinex record PPK

hi, like to install the rtk kit to 3dr solo, but i like to record the rinex on the fly with time marks and do PPK. Can i do this or the solo only do rtk on the fly?? Thanks¡¡¡

I would also really like to know if this works. Have you gotten any traction or responses from anyone to be able to do this?

That would need some firmware changes, I am not sure how well Solo is supported right now in PX4 or Ardupilot stacks but that should probably be a better place to ask.
