I'm using the example drivers/onewire/mail.js .

The instructions

  sensor.resolution = 9;
  res = sensor.resolution;
  trace("res - should be 9 :", res, '\n');

must configure the resoluton of the sensor and the example works but only during the test
If the device is not shunt down the setting is lost
In other words the configuration is done only in the RAM of the sensor and not in the internal EEPROM.
Can you verify it? maybe is only a issue of my sensors, but I test a lot of them (from unique seller)
Thank you
