Hi,
My Suunto 9 crashes every time I enable the Shimano Di2 App in a cycling activity.
I managed to isolate the problem by starting a cycling activity with no sensors connected, that is, no GPS, HR belt/wrist, power meter, cadence/speed.
As soon as the Shimano Di2 App is enabled in a cycling activity, with or without other sensors connected, the watch crashes (and soft resets) after a couple of seconds from starting the activity.
Any other connected sensors combination in a cycling activity works without issue (GPS + HR belt + Power, or GPS + Power + Speed , etc.).
This behaviour is consistent and happens every single time I enable the Shimano Di2 App.
It started about a week or so ago but worked fine in the many cycling activities that I have recorded in the past with the Di2 App enabled.
I have tried without success:
Soft reset the watch.
Re-pairing all sensors.
Hard reset the watch.
I run the latest firmware in my Shimano Ultegra 12 speed set-up:
RD-R8150: version 4.2.3
FD-R8150: version 4.1.1
ST-R8170: version 4.2.2
BT-DN300: version 4.2.0
Any guidance would be much appreciated.
Cheers!
