[BUG] Echelon Stride says found but no metrics are received by QZ

[vcampbell1985]

Describe the bug

Echelon Stride seems to connect via Bluetooth but no metrics are received by QZ.

To Reproduce
Steps to reproduce the behavior:

1. Turn on my Echelon Stride treadmill.
2. Open the QZ app on my iPhone - I have the Stride saved under profiles with virtual Bluetooth device disabled and manual device set to the treadmill.
3. QZ automatically finds the Stride and shows it as connected.
4. Press Start on the treadmill.
5. The treadmill runs normally, but QZ continues to show 0.0 and does not receive any speed or distance metrics.

Expected behavior
As it already connected easily to my echelon connect 4s, I expected it to do the same on the echelon stride and receive live workout metrics (speed, distance, incline if supported, time, etc.) so I could use the treadmill with the app.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: [e.g. iOS]
• Version [e.g. 22]

Smartphone (please complete the following information):

Additional context
Issue started while trying to connect my Echelon Stride treadmill to QZ on an iPhone 14 Pro.

QZ detects the treadmill automatically and shows it as connected via my Bluetooth, but no workout metrics are received. The treadmill operates normally, but QZ stays at 0.0 for speed and distance.

I have already tried:

• Restarting the treadmill and iPhone.
• Clearing the Bluetooth cache.
• Removing and reconnecting Bluetooth devices.
• Reinstalling QZ.
• Confirming the treadmill's built-in display is working normally.
• Generating and attaching the requested debug log.

The debug log is attached to this issue.

Hi there, sorry I currently don’t have an android device. Only iPhone and iPad.

Mmm Ok the unlock mechanism actually requires an android device. I will check in these days if I can do something about ios to ios

I will let you know

In the meantime maybe you or some friends could borrow even an old android device to test? Roberto Viola I sometimes trade time with my daughter to help.
