Android Zwift not recognizing sensors


Samsung S22, most current OS update, most current Zwift app update. New phone, doesn’t recognize my Garmim HRM and Footpod (both bluetooth and Ant+ enabled). I allowed location and unpaired all other devices in bluetooth settings, uninstalled/reinstalled Zwift, nothing worked. Both sensors had worked on previous phone, batteries are fresh.

I searched this category, can’t find anything current. Does anyone have any suggestions?

does the garmin app recognise the hrm?

Two possibilities:

  • Make sure you have the ANT+ libraries installed on the phone. I’m doubtful this is the issue as you’re not seeing anything via ANT+ or BLE.

  • Strong suspicion: you still have another device or app attempting to steal control of the sensors. 99% of the time, this is the issue that leads to the symptoms you’re seeing.

See this very tongue in cheek thread: Pssst: Yes, you do have another device connected, dummy

Thx for the responses, much appreciated! I’m still trying to figure it out. Here’s what I’ve done since the responses. Turned off computer that runs Zwift when I’m home, unplugged the ant+ dongles too. Deleted wahoo app from phone, removed the foot pod and HRM sensors, from my Garmin 945, turned the 945 off, checked Garmin connect app on my phone, no sensors connected to it, forced a stop of the connect app, installed the ant+ apps suggested, did a phone restart at each step, launched Zwift after restarts, still not finding the sensors. Never had any issues connecting sensors to Zwift phone app in the past so I’m really stumped here. I’ll keep trying, open to any advice.

Samsung S22 doesn’t have ant+ radio inside. Older Samsung devices had one. Bluetooth in my case doasn’t work well with wahoo kickr. I don’t use Windows. Trying OTG cable with ANT+ dongle, doesn’t seem to pick up signals from Wahoo. …

you’ll need to install the Ant+ apps from here:

I think you need, Ant radio service, Ant+ plugin services and Ant USB service

The last Samsung with ANT+ was S20.

And the struggle continues…

I had given up on this, but now with Levels 21-30 available, I’m hoping to get sensors connected again.

Samsung Galaxy S22, installed Ant radio service, Ant+ plugin services, and Ant USB service. Turned off Garmin 945, and I’m at a work location so no trainer or PC connected to any sensors. Garmin Ant+ Footpod and Garmin HRM2-SS, both with new batteries. Latest Zwift update and Zwift Companion. All the advice above taken, and for the life of me I just can’t get Zwift on my phone to connect to my sensors.

Anyone have some magic sauce? I’m out of tricks and tips.

So what was the result of the ANT tester app that CJ suggested? Post up a screenshot of it.

The lack of HAL service means your device is not ANT compatible, confirming what a few posters above mentioned.

Thanks for deciphering that for me! So… if I buy a Bluetooth capable HRM and Footpod, would that get me back up and running? I’m guessing that’s cheaper than a low end iPad.

No reason why bluetooth wont work for you from a phone capability perspective - some people have issues with either protocol due to interference issues and those interferences impact ANT and BT slightly differently, which is why some people prefer one over the other.

From one Dean to another, thank you! I appreciate your advice and patience, this Forum is great! Ride on! I’ll throw you a reply when I get everything going again.

Usually I use my Mi A2 mobile (Android 10) and ANT+ to connect my Saris H3 and Coospo HRM, but earlier I grabbed my Poco F3 (Android 12) for a session, which only has Bluetooth as option.

Ended up having to ride just paired to turbo, the Coospo HRM could be seen to pair, but it wouldn’t stay paired.

Will try Bluetooth on Mi A2 next time and see what happens, might be something as simple as the HRM battery is on its way out.

Success! Bottom line, no Ant+ capability on my Samsung S22, and I would have saved time and frustration if I knew that. I thought by adding the Ant+ array of apps on the phone Ant+ capability would work, I was wrong. Bluetooth works like a charm. Thanks so much for those who got me here, always appreciated.


It’s not just ANT+ apps. Samsung for example dropped kernel support for ant+ all together, so dongle for phone isnt a solution any more. Bluetooth works but in my case preformance was terrible on my Wahoo kickr. That completely stopped me from using Zwift on Linux, since I used Lutris to install Zwift.

Great to hear that Bluetooth works 4 you. In my case it was crappy. It was dropping constantly.
