hope zwift comes up with an update soon to resolve this. its been a few weeks already.
using windows.
kickr trainer auto detects when the zwift program is launched.
the HRM connects but there is no signal. HRM is working fine as i can connect it to the wahoo app.
zwift program hangs quite often too.
I have exactly the same issue. Tacx trainer which works perfectly with an iPAD when I try with my windows PC the trainer connects and I get the no signal message. I have tried all the suggestions I can find on the forum and none seem to make any difference. I take it there is no word of zwift fixing this it is very very frustrating
Hi all.
Not sure whether anyone else has found a solution but I think I’ve made some progress on this tonight after several frustrating days.
I have a Wahoo Kickr Core transmitting via Bluetooth to a Macbook Pro. Heart rate is separate via an Ant+ dongle.
After using the companion app and having intermittent success I’ve gone back to scratch and firstly tried removing the laptop and just using the Zwift android app on a Samsung S20 which connected immediately and without any issues.
That made me think that the issue was with my Macbook bluetooth rather than the turbo or Zwift.
I loaded Zwift on the laptop and got the dreaded 'No Signal screen when trying to connect.
I went into Bluetooth at this point with Zwift still open and saw that the turbo was constantly being connected and disconnected by the laptop over and over. Very odd!
I then deleted all devices and debugged the bluetooth on the Macbook. Follow these instructions and I’m certain there will be a similar process for Windows:
Fingers crossed!! I’ve restarted the laptop several times now and the Wahoo is connecting to Zwift via the laptop without any issues. The Bluetooth icon on the menu bar now has an ellipsis through the centre indicating a connection having gone through the logging in procedure on Zwift.
I’m going to slowly start connecting other bluetooth items such as Garmin watch and headphones and see whether it remains stable but well worth a go.
Hello guys, I found the solution after 3 days and trying everything! It occurred to me to replace the battery of the Ant + module (in my case an Elite Turno trainer) and now it works as it once did! Hope I was helpful!
This fixed my issue. Thanks!
Having this issue today. Worked fine yesterday and months before this. i’ve been using BT Wahoo HR, Kickr Power and Wahoo cadence sensors with no issue before today.
WTF Zwift?
i rebooted Kickr and laptop to no avail
Same issue here my spped and cadence sensors are connected but red “no signal” message on zwift app. Phone and watch both recognize these sensors. First time having this issue on zwift app.
Same here, new kickr & tickr. Does work with the app, zwift says connected but no signal. Connecting to Windows 10.
When i connect via the companion, all works accept cadence.
Bit disappointed having spend a lot of money in devices and tools to make this work…
Same problem for me as everyone else. In my case it’s with a Kickr and iPad. Zwift Cimpanion states that Zwift are aware of the problem which is with BLE.
I’ll try riding with my MacBook Pro.
Same issue here. With new kickr worked great for a couple of weeks. Frustrating.
Update: on iPad - I uninstalled and re-installed Zwift app and that seems to have solved it. For now at least.
Problem fixed on iPad with a new Zwift app released yesterday.
Still got this problem. Brand new Elite Suito on Windows 10 and haven’t been able to complete a single workout yet because the signal keeps dropping out.
I think with that trainer you can go Ant+ instead and avoid the perennial difficulties Zwift seems to have with Bluetooth connectivity. Just make sure the dongle itself is close to the trainer (less than about 2m seems to be important based on many comments here). Dongles are cheap and even if you have to get a USB extension cable to get it close to the trainer it would be worth it to avoid the bluetooth issues.
Turned out to be a faulty power cable on the trainer. Some great support from my local bike shop and its all good.
Hi All, I recently got myself the Concept 2 Model D PM5 rower. I cant seem to connect / pair Zwift to my iphone or ipad with the rower. But I used an android and its picked it up via bluetooth. Unfortunately just as most of you it comes up as ‘No Signal’. Any idea how I can fix this?
Yes! So much money and then “no signal”. The first weeks all was fine and then the pain started.
First, the problems started on the MacBook.
Then I switched to an AppleTV. At first everything was fine and then the problems started again.
Now I have the “no signal” problem on the AppleTV, MacBook and iPhone! Arghhh
Have now opened a support ticket with Wahoo.
This really makes me angry!
Today it failed again in the middle of the race!
I had no chance, I had to disconnect the power from the Kickr to make it work again!
No stable Bluetooth connection on a device for 1,200€?
This is really not funny @WAHOO
Hi Jorn, How does it work with the app?
Fyi, i have switched to Ant+ for my Windows pc and since then no issues.
But check the app first, people i know using apple (macbook) bluetooth have no issues.
Another addition to the piles of people having similar issues here.
I have the most recent version of Zwift on my Macbook Pro and use the most recent version of the Companion app for iPhone XS. The Macbook Pro is an early 2015 model and on Catalina (not on Big Sur), but was running fine until around mid way through last year (there are only issues with my HR monitor).
My setup is:
For a number of months, I have been unable to get a reading with my heart rate monitor and the pairing screen of the Zwift app for my Macbook Pro either reads zero or “No Signal” when I try to pair. Here, this is the case with both BT and ANT+.
In fact, I have purchased a new heart rate monitor and a new ANT + USB stick to try to resolve the issue. This has not made a difference.
For clarity, the heart rate monitor works when paired with the Zwift app for iPhone and with my Wahoo Elemnt Bolt cycle computer. As such, this is clearly not an issue with the heart rate monitor and, given I have just purchased a new ANT+ USB dongle, it does not seem to be an issue with that.
Separately, when using Zwift on my Macbook Pro, I use the Companion app on my iPhone to “control” and chat, etc.
Based on feedback from Zwift, I took the following steps:
This did not work and the same “No Signal” comes up on the MacBook.
This did not work and the same “No Signal” comes up on the MacBook.
For clarity, this was not a problem before when in the same room and using the same equipment. There is not an issue with either BT or ANT+ on my Kickr 2018, Favero Assioma power pedals, or any other devices I may wish to connect to my MacBook.
Separately, I noticed another issue that ERG mode does not appear to work correctly when I leave the HR monitor connected in “No Signal” mode (I tested this today and ERG would not activate on the Kickr until I unpaired the HR monitor).
Any ideas anyone?!
