Tech FAQ

  • I purchased a USB stick and OTG cable to enable ANT+ communication on my Android device, but the app I downloaded still won’t connect to my ANT+ devices. Why isn’t it working?
    • There are several reasons why you may be having problems:
      • Not all devices support all external USB accessories.  Your device may not have USB host support or a full implementation that allows connecting to all classes of USB devices, such as an ANT USB stick.  Due to the wide variation of hardware available, please refer to other online sources to determine if your device has proper USB host support.
      • Only certain ANT USB stick models are supported.  Check the model number on the back of your USB stick.  ANTUSB2 and ANTUSB-m models will work (assuming the above device requirements are met).  ANTUSB1 sticks are not supported. 
      • ANT USB support requires the installation of the ANT USB Service, in addition to the ANT Radio Service and ANT+ Plugins.  If you cannot find the ANT USB Service on the Google Play store for your device, it means that your device is not reporting that it supports the USB Host feature.
      • Not all applications will support external ANT USB accessories.  There are two reasons for this:
        • Apps may require features that are not available on the USB hardware.
        • Some apps are still using legacy ANT libraries that do not recognize external ANT devices. To be compliant, apps must use newer versions of the ANT libraries that have implemented USB support.  Please contact the app developer directly to encourage their efforts to update their app for USB compatibility.
      • Some phones will not detect the USB stick if it was connected to the OTG cable before it was plugged into the phone. Plugging the OTG cable into the phone and then the USB stick into the OTG cable may work.
      • It is also possible that you may have a hardware issue with the USB port, OTG cable or the USB stick itself.  For example, some OTG cables are known to have compatibility issues.  If you suspect a hardware issue, please contact the manufacturer for support.
