Hello,

 

I’m using two Era 100s in a stereo pair mode, and one of them is connected to my bluetooth devices. Both speakers are updated to the latest software, and I usually don’t have issues with the bluetooth playback.

 

However, I noticed that after I restart my WIFI router, I lose the sound in bluetooth mode. I can connect and disconnect my bluetooth devices with audible confirmation chimes/status LED from the Era 100 that’s being used as a bluetooth connection point. However there’s no sound playing in this case. I tried toggling the bluetooth button on the back of the speaker, and I confirmed all my bluetooth devices see the connected Era 100 speaker just fine. What’s interesting is that WIFI music playback is not affected after the WIFI router is restarted.

 

What fixes the issue is to force a power restart by disconnecting power plugs and reconnect.

 

What I don’t get is that the bluetooth module shouldn’t be affected by WIFI connection status change due to a router restart.

 

This seems like a software bug, rather than a hardware issue. Has anyone experienced something similar? Is Sonos aware of this issue?

 

PS. It seems rather obvious miss to not include a hardware power/restart button or a restart option from the app, given how most of issues can be fixed with a restart…. Not every set up will have easy access to physical power outlet..

 

Thanks.

Hi ​@bwk1224, welcome to the Sonos Community!

I’m sorry to hear that you’re having Bluetooth issues with your Era 100s. Are you able to check the Bluetooth connection of the device (like you would on a phone or computer) to see if it’s still active and showing? Also, do you have other Bluetooth devices you can test with and, if so, do they also have this issue?

I’m not sure why the Bluetooth connection would be impacted as the connection should stay even after a network reboot, but it seems like you can replicate this fairly consistently. In this case, I’d recommend submitting a diagnostics both before and after you reboot your router and play via Bluetooth. Record both diagnostics numbers and then reach out to our support team for further troubleshooting. 

Regarding having a reset option in the app, this has been requested a few times already and I’d be happy to forward this thread as another request. Our devices are designed to stay powered on all the time and have minimal power draw when powered on, while reboots are generally done when troubleshooting with the device nearby. If you need to reboot your devices often enough where this type of option is needed, then that could indicate deeper issues with your network. I’d assume that’s the reason a reboot option isn’t in the app, but that doesn’t mean it’ll never be added, I just think it’s unlikely.

I hope this helps and our team can see why you’re getting no audio via Bluetooth.

 

Hi bwk1224 !

I’m experiencing exactly the same issue, but in my case it’s with a XGIMI Mogo Pro+ projector and a stereo pair of Sonos Era 100s.

The Bluetooth connection seems to work fine initially—the LED on the speaker turns blue, and I hear the connection chime when pairing with the projector. However, when I start playing a video, no sound comes through at all, even though everything appears to be connected properly.

I’ve double-checked that the audio output on the projector is correctly set to "Bluetooth" and not the internal speaker, so that’s not the issue.

It’s incredibly frustrating, especially because the only fix seems to be a full power cycle of the speakers, which isn’t always convenient depending on the setup.

I completely agree that this seems like a software bug, and I really hope Sonos can acknowledge and address this. Bluetooth should not be affected by a WiFi event like a router restart, and yet it clearly is.

It would be great if Sonos could look into this and consider a fix in a future update—especially for users relying on Bluetooth setups like this one.

 

Hi Clemarch,

 

I totally feel your frustration with the bluetooth issue. 

 

Have you tried assigning fixed IPs to your ERA 100s in your router settings? This would allow ERA 100s to be not assigned with random IPs when your router restarts. I tried this on my setup, and it seems like the bluetooth issue occurs less often these days.

 

I’m guessing the bluetooth streaming part of the program crashes when a wifi reconnects with a different IP. I’m not saying the fixed IPs fixed my issue 100%, but it’s better now.

 

I hope Sonos is aware of the issue and working on a proper fix.
