    Yes, I have this also. On the ride to my work, the cadence sensor is working.
    If I leave the Karoo on during the work day, the cadence sensor will not work on the ride home.

    That's unfortunate. But, I guess I'll double check all the active connections next time before resuming my ride. Thanks for confirming.

    Hey Christopher, Karoo should have picked up the connections once resuming the ride.

    Please share the details such as FIT file of your ride, Serial number of your Karoo(From Settings > About > Status > Serial number) with us at support@hammerhead.io

    On numerous occasions over the months I've had the device, I've had to manually un-pair and re-pair sensors to get them back "online". It was happening fairly regularly with my Garmin hub-based speed sensor. It just happened with my TICKR HR strap. Shows as "connected" in Sensors page, but wouldn't report HR while in ride. It's like the Karoo sees it, but no longer knows how to talk to it.

    I've had some issues with my TICKR HR strap as well, but I'm 99% sure it is a TICKR battery issue.  Mine would report correctly at the beginning of a ride and then would start to freeze and only update HR intermittently.  I'd be maxed out and HR is reporting something like 120 bpm, so practically useless.

    I mounted up my old Bontrager Node in conjunction with the Karoo to see if readings were the same on both and, yes, they were.  Both would report and then freeze, only updating intermittently every couple of minutes.  Put a "new" battery in the TICKR and had the same results.  Decided to try a third battery and HR reporting is now working perfectly again. 

    No brainer, but do be sure you have a GOOD battery.  Seems like even a new battery can be weak right out of the package.  This probably applies to speed/cadence sensors as well.

    Thanks, but I've ridden many times in the last months with both my Karoo and a Garmin. The Garmin doesn't seem to have the same issue with dropped or lost sensors. I've verified this with a Stages power meter, too. It can affect both ANT+ and BLTE connections, although ANT+ has been more troublesome for me.

    Hey Doug, Sorry to see this issue on your Karoo, Sensor disconnecting mid-ride or not connecting at all is indeed troublesome for some users on selected sensors. Unfortunately, this is a known issue reported with the software team and they are working to get this fixed in next upcoming releases. The only workaround we have right now is to Pair and re-pair the sensor.

    I may have spoken too soon.  Morning commute and my TICKR was intermittent again.  Not sure if related to FW update so did a factory reset and re-pair.  Will report back after my commute home.

    On the upside, TBT worked perfectly this morning.

    I have the same problem. HR sensor disconnect when (Long time) autopause. Geonaute bluetooth HR.

    HI Claes - could you unpair and pair them before your next ride?

    I have the same problem.  I just did a century, and lost my heart rate and cadence 15 miles in.
