My speed sensor flashes red one time and then does nothing. Perfect new battery doesnt help. Leaving battery out to reset doesnt help. Anyone any idea to fix this? Thank you!
Hi ! New to the forum and this is my first post.
I have the same issue with the speed sensor 2 since after the last ride my Garmin 530 tried to update the software of the sensor. It started updating and…
Update: I contacted Garmin. Problem is known. They are working on it. New update for sensor to solve issue should come via Edge. I answered that updating the sensor is difficult as connections between Edge…
I had the same issue - the sensor was still on version 2.30 and kept disconnecting and reconnecting every few seconds, with a flashing red light.
I don't recall initiating a firmware update but today my Edge 530 notified me that a software update (4.10) was available for the sensor. It was a real struggle to apply the update but I managed it and now the connection seems stable and it's not blinking red.
It took me 5 or 6 tries before the update was actually applied...
I used the Edge because I had no luck completing the pairing over BT with the phone.
i guess your issue was different.
IMHO when red light blinks every 10 secs seems to be a fatal one.
You can't communicate with the sensor anymore and so this can't be fixed with any update, just like Ivica Angjeleski described.
Pretty strange that it can even happen.
Because risk for wireless fw update is so high... there should be some fallback/plan B.
ANYHOW, Garmin should replace all such bricked speed sensors regardless they are out of warranty already.
Simply because it's clearly their fault and destroyed fully functional sensor with the official update.
BTW, battery is drained in this situation like ***.
Fresh battery is dead in 24 hours for sure.
GARMIN, please, it requires clear statement here!!
