Forerunner 255 and HRM dual 771641.

I have a brand new forerunner 255. Ive managed to connect my HRM duel 771641. But it always disconnects itself. I ve to reconnect it manually. It doesnt stay connected more than 5 seconds. The belt is all new, with new battery.

After you paired it once, it will be always connected automatically if you start an activity. No connection without activity is possible.

Is it a device that has ANT+ and Bluetooth connectivity? Because it has happened to me before with dual devices that the two connections seem to "fight" one against the other. Disabling in the watch one of the two connections makes it stable. Use the Bluetooth one, it's supposedly more efficient than the ANT one.

Best,
