Firmware Updates - Information & Tips

 Firmware updates are vital as they include important updates to the system hardware to improve functionality.  The current firmware version is 6.88.153.

  • Firmware updates automatically begin when a driver logs into the mobile application, connects to the ELD, and gets to the app home screen.


  • Firmware updates can take up to 10 minutes to complete; ensure drivers have adequate time to complete the update before driving the vehicle.

    • During this time, the vehicle cannot move and the phone/tablet using Keller Mobile® must stay within bluetooth connectivity range

    • Note: Firmware updates complete in the background on iPhone® and iPad® devices.  The user can operate the mobile application and drive the vehicle as normal during this time. 


  • The firmware update will eventually get to 99% completion but then stay there for a few moments - this is normal

    • During this time, the ELD is being power cycled and Keller Mobile® is attempting to reconnect to the ELD once it is powered back up. 

      • Android™ users may be prompted with a bluetooth pairing request - they should press OK or Pair here, whatever the affirmative option is.  If the process to reconnect to the ELD takes longer than the application expects to, the user may be prompted with a message asking if the user would like to stop waiting.  Select Yes to stop waiting and return to the application dashboard. Then, tap on the ELD status icon in the lower left hand corner and reconnect to the ELD.


  • iPhone® and iPad® users will not be prompted during the reconnection process. This will occur in the background.


  • If a firmware update is expected, but a driver is not being prompted to update, make sure they are on the most recent version of Keller Mobile®.  The easiest way to do this is to go to the Google Play Store or the Apple App Store and see if there is an update available. If they are using a Compliance Tablet, go to Menu > System Menu > File > Check For Updates.


  • If the firmware update sits at a particular percentage for 5 minutes, please power cycle the phone/tablet, log back into the Keller Mobile® app and restart the firmware update. If it happens again, please reach out to Client Services.
