The otatool pytest calls dut.serial.close() and then immediately launches otatool_example.py as a subprocess that re-opens the same serial port via esptool. This fails intermittently because: 1. pytest-embedded's QueueFeederThread still holds a reference to the serial port file descriptor when close() returns, causing 'argument must be an int, or have a fileno() method' error. 2. The OS has not fully released the serial port by the time the subprocess tries to open it. Add a delay after serial close and retry logic for the subprocess to handle transient serial port contention. Made-with: Cursor
