Yet another remark regarding instable BT connectivity. Paired the OH1, and after 10 min in the ride the heart rate stucked at 160. I checked the sensor status and the OH1 was disconnected. I could not reconnect. So I finished the ride w/o heart rate data (THX, that messed up the training effect data as well). At home the 1030 would not connect to the Wifi, and as it turned out, to the phone. I finally restarted the device, and it was back to normal.
Totally look forward to the next ride. NOT.
