I have no idea what's going on here. Today, I ride my board on the same track for 6 miles for about 20 min and surprisingly, not a single disconnect. Then, I stop for a while to look at my phone and sure enough, connection is lost and 'reconnecting' appears on the screen. I wasn't even in motion. I just stopped to look at the app and boom - disconnected while just looking at it! After that point, it started dropping and reconnecting on a regular basis for the next half hour. Easily 5 to 6 times about 5 - 7 minutes apart.
For me, this is really an intermittent bug. I'm afraid that if I send it in to FM, the connection will be solid while they test it and say there's nothing wrong with it. But, when I get it back, sure enough it will drop on me.
My connection sometimes drops right at the beginning and sometimes not until an hour later! However, I still think the connection should never drop unless you go out of range, ow is powered off or phone is off. My OW+ has NEVER dropped.
@eckit for what it's worth:
ride style: goofy
phone location: both! sometimes I wear a jacket with a front breast pocket. Other times, it's in my back pocket.
float pads: no

I really do think it's a bad bluetooth chipset they have. It's possible they changed it and went with a cheaper chipset at a cost of performance. It's possible they haven't changed the chipset, but their hardware change has somehow affected it. Without a doubt, hardware version 4208 disables CnR. Maybe the circuitry they put in has somehow affected the bluetooth? Maybe it's just a bad production batch?
It's really scary to think about firmware updates with this issue. Knowing that the bluetooth connection is choppy and could drop at any time, you could easily brick if you tried updating your board's firmware and the connection dropped!
