Just got the UT800 and paired it to my Edge1000. I took it for a 25km test ride and have experienced 6 disconnections from the Edge. It re-connected 3 times a minute or two later but it failed the other times. What is disconcerting is that the light remained off during the failed re-connections. I had to power it back on to re-connect to the Edge.
Anyone else?. This never happened with the HL500.
Edge firmware at 14.10 & UT800 firmware at 2.10. Also connected at the time was: Garmin RTL500, Wahoo Tickr, Stages power meter & Garmin speed sensor. Bluetooth off.
