Did you find a way to optimize these out in the past?\r\n\r\nWell, I guess they were just not included.  We don't need BLE stuff, so I assumed it wasn't linked in.\r\n\r\n> p.s. would you happen to have a map file from an older micro-python build that we can compare to?\r\n\r\nUnfortunately not... I was deleting everything trying to get it to compile with the latest changes!"}}
