title_body: Cannot configure ESC: BLHeli-Configuator connects but with blank screen
upvoted_answer: Try using BLHeliSuite32 instead, since it is a BLHeli_32. I don't think BLHeli configurator works with 32 bit ESC:s, correct me if I'm wrong.
  
  If that does not work, try having Betaflight configurator open WITHOUT connecting. This has helped me sometimes.
  
  If it still does not work, you might need to connect to the ESC without using passthrough (if possible) and try to reflash it with a newer BLHeli_32 version.
