Sonos Era 100 has flashing green light but cannot be seen by Bluetooth

Yes, thanks, to borrow an Android 10+ phone for set up was to be my next step.

I presume that I can then have basic control over my speaker using the Sonos app on my android 9 phone.

You should, just make sure you keep your antique Sonos app as the current play store offered one won't load on the old phone.

I have an ancient android tablet, been out of support for years but still functions as my alarm-clock and to control my bedroom Sonos. 

I have the up to date Sonos app and was happily using this until a few days ago. My Sonos Era 100 speaker for no good reason stopped responding and it was then I did the reset etc.

I just hope that the new app gives me the basic functions with Android 9 when I get the speaker set up again.

I was able to download the Sonos S1 app, but it refused to set up the speaker.

ERA 100 is not compatible with S1.

How did you load the up to date 83.01.09 - 03/31/2026 app on your old device?

My out of support devices refuse to let me do that.

Or was it an older release as shown here?

I was running the new Sonos app and still am except it wont do a new Set Up to the Era 100.

I simply found the old Sonos S1 on Google Play, installed it and it worked. Except of course it is too outdated to set up an Era 1, haha.

I have a Samsung S8 on Android 9, but sorry I see no version information that looks like that at https://support.sonos.com/en-us/article/release-notes-sonos-app-updates

Not sure what you are looking for, but these are the app requirements: https://support.sonos.com/en/article/sonos-app-requirements

The version is in settings, genreal then about.

Too late now, but a factory reset is never a good idea, its only required if selling your device.
