couple of side questions:

1. Any idea why an .rbf built from the LME software exits when complete but a makecode rbf doesn’t?
2. Any know if there is a command code to read the bricks name. for BT that is pretty easy as it get set in the BT enumeration. I’m not sure how to get it via USB or Wifi without asking the brick. I looked through the opUiRead sub codes and didn’t see anything for name. Maybe a read line would do it?
