Update Firmware Using the Physical Controls

About this task

We regularly publish new firmware versions that improve the functionality of the Song Meter Micro 2. If your recorder is running an outdated version of the firmware, the Status Screen will display a message alerting you to the new version. We recommend making sure your recorder is on the latest firmware at the start of each deployment.

Normally, the recommended way to update the Song Meter Micro 2's firmware is via the Utilities menu (see Load a Configuration to a Paired Recorder from an SD Card). However, if you are unable to pair with the recorder, the procedure below will allow you to update the recorder's firmware without using the Song Meter Configurator app.

Procedure

  1. Set the On/Off switch to Off.
  2. Remove one battery from the battery tray. Leave it removed for at least two minutes while you complete the following steps.
  3. Save the latest firmware file to a microSD card:
    1. Download the current version firmware file from our Downloads page at https://www.wildlifeacoustics.com/account/downloads/sm-micro.

      The firmware file name is formatted as sysmicro-X.Y.smm.

      You must have a user account on wildlifeacoustics.com to access our Downloads page. Only an email address is required to create a user account.

    2. Connect a microSD card to your computer.

      If your computer has a built-in SD card slot, you can use a microSD-to-SD adapter. Otherwise, you can use a USB SD or microSD card reader.

    3. Copy the firmware file to the top level of the microSD card.

      "Top level" means the firmware file must not be inside a folder on the card.

      There must be only one firmware file on the card.

    4. Eject the microSD card from your computer's operating system before physically removing the card.
  4. Insert the microSD card into the Song Meter Micro 2's microSD card slot.
  5. After one battery has been removed for two minutes, proceed to the next steps.
  6. Press and hold the STATUS/PAIR button. Keep holding the button for the following steps:
    1. Reinsert the missing battery.
    2. Switch the On/Off switch to On.

      All three STATUS LEDs will light up solid green.

  7. Release the STATUS/PAIR button.

    The STATUS LEDs will flash various patterns for several seconds, then the LEDs will show solid Red, Green, Green from top to bottom.

  8. Press and release the STATUS/PAIR button.

    The STATUS LEDs will flash red three times, then the firmware upgrade will take place.

    The STATUS LEDs will flash green three times to indicate a successful update, then the Song Meter Micro 2 will reboot.

  9. After the recorder reboots, open the Status screen to confirm that the new firmware version is listed.
