ERG mode with Tacx Neo don't work with last update

**netangel** · January 25, 2019, 8:19am

This will not work, I’ve tried this way at the point I’d realized the current version is broken.
You can get previous version easily on internet (e.g. https://www.apkmirror.com/), but Zwift also has “data package” about 300 mb, which it downloads on install. Old version is not doing this, and you will get “Data validation error” in the app.

Hey Vincent!

I have a big problem with the last update 1.0.32519 on HTC U12+ (Android 8.0) and Tacx Neo.

Before this update all work very good with ERG mode. Since this update if ERG is ON or OFF that doesn’t change the resistance.

At the start of the workout, the resistance turns on for a minute, then turns off
1.84
Tacx Neo
4.The problem occurred some time after the Beta update. According to the information of friends who use the PC there was an update on the ZVIFT servers, but this is not certain)

With the new Software update all is working well on my configuration. I made a short test for Workout mode and Training mode (uphill and downhill).

Tacx Neo smart
Samsung Galaxy S8

Inclusive the additional new feature to change the world!

Hi Vincent, I’m using Neo 2 with Samsung S6 all was fine until latest firmware update. Very frustrating !!!

**runfje** · January 28, 2019, 6:52am

With the latest update I can confirm that it’s working again! I had resistance control working yesterday on my Tacx Bushido and Lenovo Tab 4 10 Plus.

Hello everyone !
I confirm that with the last update (available since 1 or 2 days) everything works perfectly!
Thanks zwift, even if it was a bit long

**Christopher_Dale** · January 29, 2019, 1:48pm

What update is this, as my Neo is up to date at version 0.0.18?

**Cedric_Richard** · January 29, 2019, 4:57pm

latest update of zwift beta ! no neo

**Ben_L** · January 29, 2019, 7:30pm

I’m pleased to confirm I had a successful structured group ride this evening so it all seems back in order.

**Oleg_Dubrovsky** · February 1, 2019, 11:18am

Hello all.
After updating the Android Beta, the work of Neo is restored. Gradients and coatings work.

Now cadence doesn’t work after 10 min riding… No problems with my ipad Air, but it doesn’t works with my Samsung Galaxy Tab S2 9.7 LTE… Cadence stops after 10min… F***

**Brand_One** · February 4, 2019, 1:00pm

Happy to report that resistance changes are now working on vortex.

**Hansi_Lazarus** · February 4, 2019, 3:25pm

Today started my last month, beeing a beta-idiot who pays 15 € a month, for not working software…

**John_Plampin** · February 4, 2019, 7:45pm

Hill resistance now working BUT cadence fails quickly. Its a separate BT cadence sensor and works fine via Garmin, Rouvy or Tacx utility.

**Vincent_Williams1** · February 4, 2019, 8:29pm

Hey John, does your cadence drop to zero immediately or gradually drop down? Does your cadence sensor act like this every time you start up Zwift?

**John_Plampin** · February 4, 2019, 9:23pm

It started accurately and lasted for maybe 5 minutes then went to zero. Occasionally it showed the cadence for a split second, but didnt start working after repairing devices. I’ll do some more tests tomorrow

**John_Plampin** · February 5, 2019, 7:42pm

Some more testing done but cadence is always unreliable
In the pairing screen the sensor is found, its box goes blue with the green tick but if I pedal I get 1rpm displayed - then intermittently a realistic cadence shown (eg 85) for a split second.
I also had the same on the pairing screen but with “No Signal” shown over the sensor box.
Tried a group workout and cadence showed 1rpm with the occasional realistic split second measure shown. The workout was constantly telling me to spin faster !!!

I’m using a Tacx Smart Flow with a Halfords BT/Ant+ cadence sensor, Samsung S9, all software up to date on all devices.

**Vincent_Williams1** · February 6, 2019, 1:34am

Thanks for the heads up John, we’ll be looking into this!

**Chay_Mckenzie** · March 10, 2019, 5:37pm

After using zwift android since November 18. Today I’m having this same issue. No resistance on hills. Erg mode not working/ holding power.

**Rob_Nishman** · March 18, 2019, 10:43pm

Erg mode was cutting in and out on me on my Tacx neo. It was not a software problem. The rear wire plug going into the tacx device was not fully plugged in. I pushed the plug in fully and erg mode started working perfectly again. Sometimes the extension cord can get moved around doing things like vacuuming and jiggling your Tacx plug around a bit causing the plug to pull out just enough to cause a problem. worth checking as a quick fix.
