L26-DR GNSS - $PSTMDRMMFB command (Dead reckoning) parameters

when should I send a validity flag as valid or not valid?


  1. It needs an application framework that can use a map matching system (for example, in a navigation system).
  2. Judge whether the location information output by L26-DR is valid through the host’s map matching system (including the location database of the map).

In addition, we can discuss the same issue in one post.
Thank you.
