As of the latest update 13.31 and Bluetooth 28.85 the Fenix 8 will not recognize the Bowflex. The Bowflex is Bluetooth only.
The Fenix 8 would connect to the Bowflex with previous software, 12.35 and Bluetooth 28.84 specifically, but would drop connection every 90 secs.
The Bowflex connects to a Venu 3s and another brand bike computer without any issues. It would also connect to a Fenix 6 Pro without any issues.
A ticket was open opened with Garmin Support about the previous issue with no resolution. I use this Bowflex to supplement my training. I’ve been out with an injury, unrelated to sports, and I looked forward to riding and tracking my progress on this Bowflex. $1100 and I can’t track an indoor ride. This needs to be addressed or I need a different device.
