First ride with Karoo. All sensors disconnected. Twice. :(

Hey Folks,

I just got my Karoo, and took it for it's first ride. I went on a lovely 53 mile ride along the Monterey coast. Unfortunately my Karoo didn't behave so well. Twice during the ride it lost the connection to all of my sensors at once:

• Scosche Rhythm24 heart rate sensor
• Garmin speed sensor
• Garmin Varia Radar
• Shimano Di2 shifters

Everything disappeared at the same time. The first time this happened I didn't know how to deal with it, so I rebooted the device. When it booted up, the last activity was recovered. Then I started a new ride, and an hour later the same thing happened. Rather than reboot it, I just made GPS the speed sensor of choice, and kept riding. Then when I got home I combined the two rides on Strava.

Has anyone else seen something like this happen? And most importantly, is there a way to prevent it from happening?

  Hi Ashish,

  Thanks for offering to help, and so quickly too.  :) I get the impression that your tech support team is very responsive (even during a pandemic). I really appreciate that!

  Anyway, I'll respond to the e-mail and troubleshooting steps that you sent me via e-mail.

  There appear to be a lot of differing ways the sensors can dropout, and the terminology and descriptions are not clear or consistent.

  1) Loss of individual sensors

  2)  loss off either BT or ANT+

  3) Loss of Both BT and ANT+

  4) loss before start of ride

  5) loss during ride

  6) intermittent and total

  7) Variations in sensor accuracy

  I am having problems erratically with toggling of ANT+ , noted as ride is being set up  and with sensor accuracy. The latter I am attributing to the sensors (HR & speed), not the Karoo. Something seems to be toggling the ANT+ radio off, and it is resolved with going into the Sensors App and turning it back on.

  I don't know if this could help, but I have no sensor disconnections using only ant+. I disabled bluetooth before ride, on my 3 latest rides, and got no problem. But today I connected bluetooth and ant+ before ride, and then I got all sensors disconnected on middle ride.

   

  I use this sensors:
  Garmin speed sensor
  Shimano di2
  Assioma duo
  Garmin HR
