@zucchero Who makes the IC7?
(Edit: Actually, nevermind my response here — if you previously got power (watts) data over, and it stopped, then my explanation won’t help as it must have been using CPS)
I know for the Schwinn IC4 (also called the IC8 in some markets and is also the Bowflex C6) it has two ways to send cycling data.
The first is by “Bluetooth FTMS (FiTness Machine Service)” and this protocol sends power (watts) and cadence (rpm). This is used in apps like Zwift, Fulgaz, Rouvy, MyWhoosh, etc. However, this protocol is not supported by Suunto nor any other smartwatch maker I know.
The second protocol is by “Bluetooth CSCS (Cycling Speed and Cadence Service) which only sends cadence data and not power. This protocol is primarily for the use of the Peloton app, that does not support FTMS (and indeed, has no way to get cycling power from non-Peloton bikes). If you see cadence but not power then Suunto may be using this protocol with your IC7.
There’s another protocol “Bluetooth CPS (Cycling Power Service)” which obviously does send power (watts) and cadence (rpm), but the Schwinn/Bowflex bikes do not send use this (despite estimating power) and only use FTMS. If your bike uses CPS then Suunto should be able to get that data.
