Update Firmware on RM5 Units

Before updating the firmware, ensure that you are updating to a newer version. If the firmware version to be applied is older than the unit's current version, this action will downgrade the unit's firmware and may cause application errors. AI generally recommends using the latest version of firmware on all remote monitoring units.

As of Bullhorn Tools v3.0.30009, firmware update files are automatically downloaded to the mobile device when the app is launched and the device is connected to a Wi-Fi or cellular network. A manual update check may also be performed from the firmware download page.

    Once the firmware update has been uploaded to the RMU, the firmware update will complete on its own. If Bullhorn Tools disconnects from the unit at this point, it will not be able to reconnect until the update is complete. The technician may leave the site at this point and configure the unit using Bullhorn Web.

    If the technician remains at the site, Bullhorn Tools will restore the unit settings at the conclusion of the update process.

    During the firmware update process, the blue Wake/Config LED will indicate the status of the unit:

    • The LED will blink slowly while the firmware is updating

    • When the firmware update is complete, the LED will turn off, and then turn back on, showing a solid blue light

    • After about one minute, the LED will blink rapidly. At this point the user may perform a magnet swipe and reconnect to the unit

  8. If Bullhorn Tools reconnects to the same unit, it will restore the settings saved at the beginning of the firmware update.
