Edge 530 sensor dropouts since installing 8.0 firmware

After installing the new 8.0 software/firmware on my Edge 530, I'm getting repeated sensor loss and then Found messages (about every 5-15 second) while on a ride.

It's only the connection to my SRAM eTap that's having this issue and it wasn't occurring with the 7.10 version.

There's no battery warning from the eTap and they (front and rear derailleur) are shifting just fine.

Other ANT+ devices are all Garmin and no dropouts seems to be occurring for any of them: Remote, HR, Vector Power Meter Pedals.

I'm going to try removing the device and rediscover it as well as fully charge the eTap batteries to see if that makes a difference.

Anyone experience anything similar with the new 8.0 version?

  • That may be a workaround but the problem did not exist before the 8.0 update. A proper "solution" would be a code fix that allows wifi to co-exist with other radio protocols as before. Might be a good clue for the engineers to look at.

  • the problem exists with 9.10 firmware.

    this is my latest firmware  and i have various dropouts with my sram's red etap 11s levers,which are finding/loosing the connection of the gears all the time.batteries are strong but the signal is going and coming about four times per minute.

  • I have experienced persistent and periodic drops from power pedals and cadence during indoor workouts, even turining off main power in my house and any battery powered wireless sources, including my iPhone. I also checked that neightbors were using low 2.4 channel number at very low rf power. So I think that the problem resides somewhere else (sensor mutual interference?). During the drops, my 530 was connected to polar HR, duotrap S, Assioma and Elite Direto trainer, using ANT+ for all of them.

  • yesterday, i downgraded the software to 7.10 and the problems remain the same.

    maybe the power pedals (Assioma) make conflict.

    anyway the Garmin software/firmware sucks.

  • I bought the Garmin recently (coming from Polar M460). In the first month of use in indoor and outdoor workouts, I had no problem with dropouts. It has only been happening for a few days. And I haven't done any firmware updates in this period (except the first update to 9.1). 

  • I was having the problem on 7.x firmware. Still having the problem. Nothing has changed.

  • I'm still having dropouts.

    I have contacted Garmin 2 months ago.

    I wrote back yesterday and they stil have no fix.

    VERY disappointed!!!

    Considiring swtiching to Wahoo.

  • I have Edge 530 (fw 9.1) and have constant dropouts with Varia RTL515 radar. Other sensors (speed, hr, favero power meter) work fine. Usually the first 15 minutes of the ride the connection is somehow stable but the longer the ride the more dropouts I get. I think I get "radar disconnected" message up to 50 times per hour... I also get ocassional phone disconection but other sensors work fine. I got a replacement Varia but still the same issue. I cannot believe Garmin isn't able to fix this for  9 months. Just unbeliveable...

  • I tried factory reset, firmware 7.1, removing all other sensors and phone, upgrading back to 9.1. Nothing helps. Still get constant disconnections.

  • Depressing to search on this issue and find this thread has been going for over 9 months and no apparent solution. Is it worth trying reverting to 7.1 or not?
