Troubleshooting Bluetooth Connection

Fix the most common pairing and audio problems with Stem 2.

3 min read. Updated June 25, 2026


Most connection issues with Stem 2 come down to pairing state, battery, or interference. Work through these steps in order. (Stem 1 connects over USB, not Bluetooth — see “How to Connect Stem 1”.)

Stem 2 will not appear

  • Make sure Stem 2 is charged and powered on (hold power ~3 seconds).
  • Confirm it is not already connected to another phone or computer.
  • On first power-on the center LED pulses for pairing — open your device’s Bluetooth menu and tap Stem2.
  • Turn Bluetooth off and back on on your device.

Audio cuts out or stutters

  • Move Stem 2 closer to your device to reduce interference.
  • Step away from crowded Wi-Fi and other Bluetooth devices.
  • Charge the speaker — low battery can weaken the connection.

Stems will not split

Splitting runs on a live Bluetooth stream and needs Wi-Fi plus a linked StemFM account. Make sure audio is actively playing, then hold the STEM button (the small circular button by the track buttons). If the animation turns red, the split failed — check your Wi-Fi and account link and try another track.
