Instable connection to smart trainer with Ant+ after firmware update to 21.22

I have used my Garmin Forerunner 955 to control my smart trainer elite suito.

The connection via ant+ worked flawless for the last year. After Firmware update of FR 955 to 21.22, the connection is very instable and the 955 is now useless as a Controller for the smarttrainer.

Description of the procedure:

  • The smarttrainer is found by the 955 immediately.
  • The connection is established and the smart trainer indicates a ant+ connection.
  • After start of the Workout, the smart trainer indicates that ant+ connection is lost and the power is no longer controlled by the 955. The 955 however does not indicates a lost connection.
  • The connection will not be re-established automatically.

What i have done already to fix the problem without any success:

  • Reboot FR955 and smart trainer
  • Factory reset of FR955
  • Update smart trainer Firmware 
  • Smart trainer works flawless with BT comnection to Smartphone
  • FR955 has same connection issues with other smart trainer (also elite suito)

Is this an issue with 21.22 formware  of the 955 or is it a hardware problem with my specific FR955.

    Did you check the stand-alone mode on your trainer?

    I had a similar issue, open a ticket with Elite, and they provided me with this link:

    https://elitesrl.zendesk.com/hc/en-us/articles/6877833313938-Stand-alone-mode-for-interactive-trainers

    I turned off the plugged option, and it's been working flawlessly since then.

    Hey many thanks for this advice. Will try if this helps and report here if this solves my issues.

    I have testet it today again witb no success.

    My e-training app reports an error when i try to enter the Parameter "stand alone/ plugged in trainer"

    I have tested it with both, the Android App and the Windows PC App from elite. All other parameter could be accesed and modified. 

    What i have tested now as well, is a connection with my Windows PC running mywoosh together with an ant+ dongle. This worked flawless without any Interuption.

    So my conclusion is again, that either the New fr955 Firmware or the fr955 Hardware is the problem.

    Has anyone else problems with ant+ connection to a smart trainer with the new garmin firmware?

    I learned that Elite trainers expect more frequent active control from ant+ devices than the forerunner sends.

    That was the reason for changing the plugged stand-alone setting. 

    I have no issues with my watch.

    I suggest you open a ticket with Elite to determine what's happening on both sides.

    Elite Support provided a json file as a work around for the known problem that the standalone Feature can not be deactivated.

    It works now. Power is adjusted again using the garmin watch. Even though the ant+ connection is still instable (green ant+ light flashing all the time).
