@ook Thanks, have also tried both full and partial serial numbers (removing digits at the end).
I am doing this:
Phone (iPhone 13, iOS version 26.3.x)
Suunto App > Manage connection > Forget
Terminated Suunto App
Settings > Bluetooth > “Suunto Peak 9 Pro xxx” > Forget this device
Settings > Bluetooth > Off
On the watch (Suunto 9 Peak Pro)
Connectivity > Paired Devices > Mobile App > Forget
Connectivity > Discovery On (is usually off)
On the computer (MacBook Pro, M3 Max, late 2023, macOS 26.3.x)
Once:
Given VsCode access to Bluetooth. macOS have asked that should approve, I have manually enabled it.
In VsCode settings, supplied the serial number of the watch (both full and partial)
Turned Bluetooth on (the watch has been paired with the computer but this only works when using LightBlue, bluetooth is usually off)
In VsCode > Suunto Watch > Refresh, nothing is found
