I have 2 S1 Pro with battery inside. I connected S1 Pro with my iphone and when I open Bose Connect App, I saw S1 Pro speaker. but App can't auto connect it, I drag to connect S1 Pro but I still can't. Please, help me.
Lets try clearing the paired Bluetooth devices list and see if that helps.
To clear the speaker's memory of previously paired Bluetooth devices:
Turn the speaker on
Press and hold the Bluetooth button for about 10 seconds. (Note: The Bluetooth button will be either lit [connected] or flashing [trying to connect]. After holding the button for 10 seconds, the light turns off briefly to confirm the device list is cleared.)
Remove the S1 from your phone's Bluetooth device list
