Hi!

As noted by several users, upgrading to iOS 26 led to unstable Bluetooth MIDI connections with the DM48X.

With the release of a bluetooth module firmware update, this issue is now resolved. It only takes a few minutes to update your instrument:
  • Download the Bluefruit Connect app to your iPad or iPhone via the App Store.
  • Connect to the DM48X within the app (may occasionally show up as DfuTarg)
  • Update to the latest version (v0.9.0).
  • Ensure the update is complete before restarting your DM48X.
