    Hi Adam et al.,

    I have a Lezyne Macro GPS (yr 10) which I am coming to like as I learn how to use it. I also have a Magene GEMINI 210 cadence sensor ($20 china version). While my Macro sees it I can not get it to record any data. Is there any way to get this to work? 

    Thanks Doug, in Canada

    Hello ccdame,

    I have 2 of those cheap sensors and a Micro C GPS.
    I can get it to work as speed or cadence with ANT+, it gets recognized and displays data.
    If I search for them as BTLE, in both modes it gets recognized, but will not display any data. It will say connected but always at 0.
    Both sensors works on ANT+ or BTLE with third party android apps, but it will only work on ANT+ for the Lezyne.
    Another issue I find is that it lags big time while using those sensors, and on both modes, it has a low value cut off. In cadence, it will jump to 0 bellow 28 to 30 rpm.
    The most disturbing one is the speed, bellow 4.8 to 5 kph it will jump to 0. This combined with the 5 seconds lag before even starting to display data always mess up the distance data of my ride.

    Hi Akira,

    The first and most important question here is: are those sensors on the list of supported sensors linked above? If they are not, there's not much troubleshooting we can do.

    If it's a combined speed and cadence sensor, make sure that it's paired under speed/cadence and not separately.

    Additionally, if a sensor is reporting weird numbers, that is the numbers the sensor is reporting. Our devices only display what they're told.

    I know those are not listed, that's why I'll get a Wahoo or Garmin later, at least for speed. I've seen people saying magnetless sensors have a lag as to when you start getting data displayed on the screen, as much as 5 seconds.
    If those Garmins or Wahoos will record on low speeds, say 1 or 2 kph, then it would be ok for me. If they cut to 0 on say 5 kph then I would use GPS instead as sometimes while off road I would drop speeds on climbs bellow 5 kph, this combined with the 5 sec lag will not even record long climbs for me as it has happened with these cheap not listed sensors.

    Hi Akira,

    Since I'm currently using an FSA Powerbox, I can't use our speed/cadence sensor because I'd have redundant cadence readings. As a result, I'm using a Wahoo magnetless speed sensor, and I've never seen a 5 second lag in readings.

    If you are only moving 1 or 2 km/h, GPS might not think you're moving either. You would be better off with a speed sensor.

    Good to know. Ill try getting the wahoo one as it is both ant+ and btle compared to the garmin one.
