nRF Connect Device Manager version 3.4.1
Updated At: 2026-08-26
Changes: This version fixed a bug in our SQL script causing some chunks not to be sent to the nRF Cloud.
nRF Connect Device Manager version 3.4.0
Updated At: 2026-08-13
Changes: In version 3.4 we changed the order in which firmware images are confirmed on multi-core devices, making sure the app core image gets confirmed first. Some implementations of McuManager were complaining about this reporting "Downgrade prevention", which clearly wasn't the case. All good now.
nRF Connect Device Manager version 3.3.1
Updated At: 2026-07-13
Changes: In this version we improved the Observability feature. It now correctly identifies an invalid Project Key and notifies the user.
nRF Connect Device Manager version 3.2.0
Updated At: 2026-06-19
Changes: This version includes minor updates and bug fixes.
nRF Connect Device Manager version 3.1.0
Updated At: 2025-12-10
Changes: This version adds an option to update a device with a Firmware Loader.
nRF Connect Device Manager version 3.0.3
Updated At: 2025-10-14
Changes: This is a bug fixing release. We improved how a network error is reported when nRF Cloud OTA returns unexpected status. Also, DFU with Direct XIP was fixed for multi-core devices.
nRF Connect Device Manager version 3.0.2
Updated At: 2025-10-07
Changes: This is a bug fixing release. We fixed an app crash when Image 2 was selected in Test, Confirm or Erase commands. Also, erasing slots for Images 1, 2 or 3 now sends the correct slot number.
nRF Connect Device Manager version 2.7.0
Updated At: 2025-08-14
Changes: This version adds support for DFU using Firmware Loader mode.
We also fixed the Schrödinger's DFU bug, which caused an update to be reported both as a success and a failure. The bug is now dead.
nRF Connect Device Manager version 2.6.0
Updated At: 2025-07-09
Changes: This version adds 2 checkboxes to Image / Advanced / Reset. If you feel lucky, you can now try to force reset or even reset to bootloader. But most probably, you won't notice a difference. Sorry! As a consolation prize we also updated the scanner screen a bit. Will you find 3 differences?
nRF Connect Device Manager version 2.5.0
Updated At: 2025-03-31
Changes: In this version we added support for Fast Pair firmware update intents.
