Craches on venu. Just giving me and small iQ icon and nothing happens :( really wanted this to Work with zwift

Works well on Garmin Venu and but the companion Android app required means you only have 8 mins of recording before you are met with the pay wall. I upgraded and it's been great for virtual cycling in RGT Cycling and Zwift. One Criticism is that the position of the data fields isn't very central on my Venu

Very hit hand miss as to weather Zwift picks up and shows the option to pair with this. When it does, it works roughly but it doesn't transmit HR at all. Shows on my watch but can even get it show to on Zwit but once paired Zwift just says "No Signal". The buttons in the companion app for Android to increase and decrease stride length need to be MUCH BIGGER. I'm constantly having to manually adjust the stride length to get it to match the speed I'm actually doing.

2020/05/18, BIPR

You're right we can make the buttons bigger. It was formerly not designed to adjust step length multiple times. Maybe the Manual Mode would be better for you if you want precise speed recording...? For HR, did you tried to pair only HR ? Sometimes Zwift has trouble managing two sensors (HR and speed) with the same address ?

No transfiere cadencia de reloj a treadmill smart speed para ios

2020/05/18, BIPR

You're right, we don't have a Companion app for iOS, you need to use it with Android Treadmill Speed Transmitter app.

2020/05/14 | バージョン3

Una lastima que no funcione en un fenix 5 y en un fenix 5s. Instale en fenix 5 y reinicie aún así a los 3 segundos salió el cartel iq!

It does run, but it does not broadcas and then it crashes within couple of seconds before i get completed activity notification on the Garmin Connect. Vivoactive 3 Music, its not working (not detected in zwift as HR device, nor in Strava)

2020/05/18, BIPR

Hi, you need to use it together with Treadmill Speed Transmitter on an Android phone.

2020/05/09 | バージョン3

it can run on my vivoactive HR but cannot transmit data to my p10+.

2020/05/18, BIPR

The Vivoactive needs to be paired with the phone and Garmin Connect installed. You need to use the Treadmill Speed Transmitter app in Garmin mode.

Cant understand what is S ON, S OFF, S CONT

2020/05/18, BIPR

S means Saving, if you want to record a workout to Garmin connect or not...

I and my wife have a 935. In my watch the app is working perfectly. But my wife's watch shows the IQ! message after 3s. I already did all that you recommended, but it didn't work.

2020/05/18, BIPR

Thanks for the feedback, we are working on the IQ! to understand what happens with some devices.

2020/04/24 | バージョン3

It works well for Fenix5 with arcade fitness but zwift cannot detect the HR speed transmitter. Any new fix?

2020/04/25, BIPR

Thanks for your feedback. It is much more easy with Arcade since we manage both emitter and receiver... With Zwift, you need to connect through the Companion app on a separate phone : The Windows direct connection is not completely reliable.

2020/04/23 | バージョン3

Don't work with fenix5 always create Speed T to much. Please quickly fixed this bugs.

2020/04/24, BIPR

This is not a bug on our side and this is why we advise to connect through the companion app. There is no way for us to fix this as it is due to automatic mac address change implemented by phone manufacturer. It occurs when Zwift connects to the device to see if speed is available. We implemented the conection procedure differently with Arcade Fitness, if you want to try...

Work perfectly before. But now i get IQ with exclamation mark on my VA4

2020/04/24, BIPR

You need to start the watch app before anything else. Try to reboot the watch, sometimes, it helps... As we didn't publish a new version, maybe a firmware update or something else caused this issue to appear...

Francesco Tiralongo
2020/04/22 | バージョン3

Do not work on my Fenix 5. I followed all your indications for resolve the problem but the problem still persist... bad. Unistalled.

2020/04/24, BIPR

I am a bit surprised, although the exclamation mark issue can sometimes occur on 5+, 5x, 5s, we have fully tested the app on a Fenix 5 and had no issue with it...

2020/04/20 | バージョン3

Hola....instalé Swift en mi PC...tengo un forrunner 935...instalé la app....puedo vincular todo como para ver mis datos de entrenamiento en Swift....!? Como debo hacer...!? Gracias

2020/04/24, BIPR

Everything is explained here : You need to connect through Zwift Companion on a separate phone than Treadmill Speed Transmitter

L’application qu'il me manquait sur ma Garmin 235. Est-ce compatiblie iOS?

2020/04/24, BIPR

Merci Michael pour ce retour. Nous n'avons malheureusement pas d'appli compagnon iOS et n'irons pas dans cette direction dans la mesure où Garmin a affiché qu'ils intégraient l'envoi de données nativement en Bluetooth Low Energy dans leur dernière génération de montres.

I've installed IQ App, Android App and I can see speed, cadence and heart rate on app. I can also connect Zwift to the app (speed, cadence and hr sensors) but data is not transmitted to swift (although it's displaying fine in Android app).

2020/04/18, BIPR

Feel free to come back to us per mail. We advise to use connection through companion app on a separate device instead of Windows direct connection. Furthermore, there is a few thing to check in order to make the connection work, you can have a look at :

The app still looking for gps location which is bad. It should be locked on accelerometer sensor insted of gps. Your manual full version app really works well on my zwif by using phone. Plss fix this. Im using fenix 6.

2020/04/18, BIPR

Thanks for your feedback, it may search for GPS but speed should be estimated based on cadence and step length. Could you please come back to us per mail to give us a bit more details and we'll fix this.

Sergio Rocha
2020/04/15 | バージョン3

Same problem as everybody. App works on phone and watch. But as soon as it starts on my 645 Music, I get the IQ with exclamation mark. Yes, I did reboot both, and the same problem happens.

2020/04/14 | バージョン3

Doesn’t work with garmin Charlie...iQ exlamation point mark after 3 seconds in which i see hr/bpm/cadence Can you explain me how to use zwift and if i can upload on zwift the hr data i collect from garmin charlie. Thanks

2020/04/15, BIPR

Please try to start the watch app first and reboot your watch after app installation. If it still doesn't work that means that there is probably an issue with this watch model.

2020/04/14 | バージョン3

L application fonctionne bien chez moi pour Zwift. Pour infos, j'utilise l app « treadmill speed transmitter » sur un galaxy s9 (+appli garmin connect), l’appli « HR Run transmitter » sur ma Garmin Fenix 3 HR et enfin l’appli Zwift sur un galaxy S6

2020/04/15, BIPR

Merci pour votre retour. Bon exercice pendant la période de confinement.
