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 is great for you but comical from Garmin. if you have the latest FW on the brand new unit, the chances are that you'll have the same issue. Whatever you do, don't install the latest FW if you are offered a choice !

  • Thank you for working with your local support team to get that exchange set up. If this does not resolve your issues, this is still an ongoing internal ticket and we hope to have positive news to share soon. 

  • I know that now, like everyone else. The 530 was new at the start of January, so had a few FW updates since then. 

  • Yeah this is what the local support team said more or less. If it did not resolve the issue, then to get back on to them Thumbsup

  • Both of my garmins are from may 2020, never had a problem since v8. It had no issues before. I don't think build date has anything to do with this. 

  • Scroll up. Going back to 7.1 resolves all the dropout and Bluetooth issues. This is true for all the 30 series devices except for the original 1030 which uses a different firmware base. Garmin knows they broke this and they will likely eventually resolve it. In meantime 7.1 works as you would expect. 

  • I just had a second occurrence of the frequent "##### Found" messages, this time the message was related to the Garmin speed sensor. However, I was also getting pauses on TrainerRoad which uses a Ant+ dongle to receive the signals from the bike sensors. I ended up changing the battery in the Speed sensor (one of the newer ones that doesn't require a magnet) and it solved both problems: no more pauses in the TR workouts and no more "Found" messages on the Edge 530 head unit.

  • I've logged a ticket with support and am tracking with some sort of diagnostic mode enabled. Would you believe it, I've had no dropouts today !

  • Interesting, I ran for a while with the ANT+ debug/logging turned on, it didn't seem to affect battery life or performance, if it fixes that issue or works around it, great, but hopefully it might provide them with some data, if it does occur,

  • Today i had Di2 sensor dropouts and a stable HRM. Will record a few rides and see what happens.
