    My Garmin Cadence sensor (paired with an Edge 25) is now only reading occasionally, most of the time the Edge can’t find it.

    I’ve tried clearing sensors from the Edge and repairing but half the time it can’t pick up the sensor, despite trying to wake it by shaking it for 5 seconds, and despite confirming the battery is healthy (green LED flashes for 5 seconds when I re-insert battery).

    I typically ride with bluetooth on out of forgetfulness anyway, and I’ve tried turning off my phone WiFi/data, but no success.

    Does anyone have any experience with this?

    The Garmin picks them up instantly and they just work!

    Good Luck!

     

    Thanks, that was going to be my next question. The re-boot and re-pair only worked on the kitchen table last night, no pairing on bike this morning.

    My speed sensor is actually a Wahoo and it’s been fine, so I guess I’ll give them a shot for the cadence sensor too.

    I had an old style cadence/speed sensor that simply died… I replaced the battery but no joy.  Oddly it still flashed its lights in test mode, but no output to the head unit.  Replacement one has been as good as gold for years, so just bad luck.

    Only time will tell, even when it wasn’t working, it still occasionally gave a readout.

    Frustratingly I’ve lost the receipt so it will be bad luck otherwise as I’ll be shelling out for a new one! Good to hear your replacement has kept on working, and at least this time I’ll keep the receipt…

    Cleared all sensors from the head unit, re-paired cadence sensor, and everything *seems* hunky dory.

    If it drops out again I’ll replace the battery.

    Cheers

    Hopefully your fix will work.

    Easiest thing Is to put a fresh battery in, if that fixes it great, if not, only £2 and a couple of minutes down.
