How Do I Use Bluetooth on My Sonos Era 100?
- Speaker not set up on WiFi first (required)
- Not in Bluetooth pairing mode
- Phone Bluetooth off / out of range
Problem Description
You're using or troubleshooting Bluetooth on your Sonos Era 100 — it won't pair, won't enter Bluetooth mode, or switches unexpectedly. Unlike older Sonos speakers, the Era 100 has both WiFi and Bluetooth, but it must first be set up on WiFi in the Sonos app before Bluetooth is available.
Why This Happens in Real Homes
The Era 100 has Bluetooth on top of WiFi, but Sonos requires you to set the speaker up on WiFi in the app first — Bluetooth isn't available on a brand-new, un-set-up Era. Once it's on WiFi, you use the Bluetooth button on the back to pair a phone directly.
Start by finishing WiFi setup, then hold the Bluetooth button until it enters pairing mode and connect from your phone. If it won't pair, make sure it isn't already connected to another device and that Bluetooth is enabled for it; a not-yet-WiFi-set-up Era is the most common "no Bluetooth" cause.
Symptoms
- Bluetooth will not pair
- Cannot enter Bluetooth mode
- Bluetooth option missing
- Switches off Bluetooth
- Will not connect to phone
- Bluetooth audio drops
- No Bluetooth button response
- Paired but no sound
Recognize these? Here's what usually causes it.
Common Causes
- Speaker not set up on WiFi first (required)
- Not in Bluetooth pairing mode
- Phone Bluetooth off / out of range
- Already connected to another device
- Bluetooth toggled off in the app
- Firmware out of date
- Interference on 2.4GHz
- Paired to a stale device
Most fixes happen in the first 3 steps.
Smart speakers are always listening for the wake word when unmuted. Review and delete your voice history regularly in the app privacy settings. Never place the speaker in bathrooms or near water sources as moisture can permanently damage internal components.
Step-by-Step Solution
Set up WiFi first — Bluetooth requires it
The Sonos Era 100 must be set up on your WiFi network through the Sonos app before Bluetooth works. You cannot use the Era 100 as a Bluetooth-only speaker out of the box. Complete the full WiFi setup in the Sonos app first. After that, Bluetooth is available as an additional input. This is a Sonos design choice — the speaker needs WiFi for firmware updates, Sonos app control, and multi-room grouping.
Put the Era 100 in Bluetooth pairing mode
Press the Bluetooth button on the back of the Era 100 (it has a Bluetooth icon) until you hear a chime — this puts it in pairing mode. On your phone, tablet, or laptop, go to Bluetooth settings and look for the Era 100 in the available devices list. Select it to pair. The Era 100 supports Bluetooth 5.3, so it connects quickly and maintains a stable connection at up to about 30 feet.
Switch between WiFi and Bluetooth sources
The Era 100 can play from WiFi (Sonos app, AirPlay 2, Spotify Connect) and Bluetooth, but not simultaneously. When you start Bluetooth audio from a paired device, it takes over the speaker. To switch back to WiFi streaming, start playing from the Sonos app or use AirPlay — the WiFi source takes priority and Bluetooth audio stops. You do not need to disconnect Bluetooth manually.
Pair multiple devices
The Era 100 remembers multiple Bluetooth pairings but can only actively stream from one device at a time. To pair a second phone or tablet, put the speaker back in pairing mode (press the Bluetooth button) and pair from the new device. To switch between paired devices, disconnect Bluetooth on the current device and start playing from the other. The speaker reconnects automatically to the most recent device that starts playback.
Bluetooth vs WiFi audio quality
Bluetooth audio on the Era 100 uses the SBC and AAC codecs. WiFi streaming through the Sonos app, AirPlay 2, or Spotify Connect delivers higher quality audio because WiFi has much more bandwidth than Bluetooth. If audio quality matters, use WiFi whenever possible. Bluetooth is best for quick playback from a guest device, playing audio from apps that do not support Sonos or AirPlay, or using the speaker when your WiFi is down.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Place your speaker in a central location at ear height for best voice pickup. Avoid corners and bookshelves which muffle the microphones. If you have multiple speakers, set up multi-room audio groups so music plays in sync across rooms.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
