One of my Android devices connects immediately, but how can I make my other Android device connect faster?
Difficulty logging in again.
I just upgraded to a device with Android 6.0 but now I can't detect the Wind Instrument?
Android drops my connection after a few minutes, even with good signal strength. Can I prevent that?
Is there a PIN code for pairing with Bluetooth 4 or 5 (Bluetooth Low Energy)?
No, the Wind Instrument does not need PIN codes, and they are not asked for on iOS. On Android, if you do the Scan and Connection using the SailTimer API-WMM app (not in Settings), you should not see any message asking for a PIN code. Also make sure that Location Services is on (since GPS data is needed for calculating Apparent/True wind, wind angle and Magnetic/True North).
