  I am unable to update the firmware in my Aranet4 CO monitor because I get the error message that the device can't update firmware while calibration is in process. This happens, of course, when calibration is completed. There is no calibration in progress. How do I get the device to stop thinking it's calibrating so I can update the firmware?

  Hello xenu007, and thank you for your question.

  Please check the switch described in the Aranet4 manual on pages 3 and 4. 

  Please find the manual here: https://assets.aranet.com/documents/Aranet4_HOME_TDSPC0H3_User_Manual.pdf

  please try to perform manual calibration without teh app like described on page 3. If after this still you can not update, please remove batteries for 15 minutes and try the upgrade.

  please let us know if you have any questions.

  I tried the manual method three times, and the only thing that happened was the unit restarted-- but no calibration. I turned off the unit for over 15 minutes, and nothing changed. It still indicates that the unit is calibrating when I attempt to update the firmware.

  Dear xenu007

  Please try the following steps:

   

  •             Take off the batteries of your Aranet4 device for 15 minutes.

  •             Make sure the Bluetooth switch at the back of the Aranet4 is ON.

  •             Uninstall the Aranet4 app on the phone.

  •             Delete Aranet4 from the Bluetooth-paired list on your phone.

  •             Restart your phone.

  •             Install the Aranet4 app from the Google Play Store or App Store.

  •             Connect the Aranet4 sensor to your phone using the Aranet4 app; you should be prompted for a 6-digit PIN code
